Greubel Forsey | Art of Invention – Double Balancier Convexe: A-Sculpture of Time

Greubel Forsey | Art of Invention – Double Balancier Convexe: A-Sculpture of Time

The foundations are laid and development continues. After unveiling its Balancier Convexe S2, Greubel Forsey continues to establish its new and assertive identity. The Double Balancier Convexe
is its latest expression.


With every invention, Greubel Forsey has added a significant milestone to the history of watchmaking. The Double Balancier, patented in 2007, is one of them. It was first demonstrated in an
EWT (Experimental Watch Technology) prototype, with two superimposed regulating organs inclined at 20°. A second iteration followed soon after, this time in a six piece unique edition with the
two regulating organs positioned in different three-dimensional planes and inclined at 35°.

Finally, in 2016, Greubel Forsey presented the invention in its current, double-patented form: the two balance wheels are dissociated, inclined at 30° and separated by a constant spherical differential which calculates their average timing rate.


Today, Greubel Forsey unveils a new timepiece emphasizing the architectural dimension of its 6th invention that is the Double Balancier. The three regulating organs (two balance wheels, one differential) occupy more than half of the dial and provide unprecedented depth. The timepiece is contrasting, highly technical and more
contemporary than ever.

Double Balancier Convexe


The timepiece gets its name from the convex profile of its 43.5 mm titanium case. It’s plunging lines that hug the curve of the wrist raised significant technical challenges, requiring the
sapphire crystal and above all the movement to adopt to this unique shape.

This new composition showcases its movement spectacularly. The gear train emerges from below the surface of the seemingly semicircular black-treated titanium bridge and extends into
the hour and minute hands which tower above it.

The semicircle itself is rendered asymmetrical by an opening for the barrel cover, central hours and minutes indication, and by an opening which provides space for the small seconds indication below it. The engraved and lacquered minute indexes are nested within the three-dimensional chapter ring, but the polished hour indexes surpass it, plunging deep into the movement.

Double Balancier Convexe

Each hand has its own geometry, finish and color, depending on the role assigned to it. The hour and minute hands take on a curved profile and are filled with Super-Luminova, complementing that of the hour indexes. The small seconds and 4-minute hand indicating the rotational speed of the spherical differential are in polished blued steel while the power reserve is indicated by a polished and openworked hand with a red tip.


In the lower half of the Double Balancier Convexe, each regulating organ is sculpted individually. The two balance wheels, although identical in shape and function, occupy different planes and thus offer a complementary spectacle. The center bridge is in itself a showcase of the creative excellence of Greubel Forsey: multi-level, openworked and black polished with several
interior angles, it carries the hour and minute hands above the movement. The inclined escapement platforms are straight-grained with handpolished beveling and countersinks, while the
differential bridge and balance wheel bridges are flat black polished with further hand-polished beveling.

Every single component is hand finished to Greubel Forsey criteria and thus stands out on its own, and at the same time it contributes to the striking overall æsthetic of this timepiece.

Double Balancier Convexe


The bridges and mainplate of the Double Balancier Convexe are in frosted and black treated titanium. A new font has been adopted for the power reserve and different elements throughout this timepiece. On the barrel cover, we discover relief-engraved text, circular-grained with polished chamfer, describing the properties of the two coaxial barrels in series with rapid rotation (one revolution in 3.2 hours). They drive a 374-part movement, endowed with a 72-hour chronometric power reserve materialized by an openworked hand.

The integrated and profiled lugs reinforce the compact and ergonomic character of this timepiece. They extend onto either a textured rubber strap or titanium bracelet. Last particularity: the
Double Balancier Convexe, like most of the contemporary creations of the Atelier, is now water resistant to 100 meters – a detail that does not mislead on its vocation to be worn daily, in all circumstances.

RaceBird flies for the first time with successful test on River Po

RaceBird flies for the first time with successful test on River Po

E1’s innovative electric foiling raceboat took flight for the first time on the River Po close to San Nazzaro in northern Italy, with the RaceBird prototype successfully completing a series of tests and performance runs with ex-powerboat champion Luca Ferrari behind the wheel.

The RaceBird engineers conducted a number of technical tests and systems checks to assess the overall performance and reliability of the boat and the various electrical components.

The testing schedule, which will continue for several weeks, will consist of straight-line tests, qualifying runs, and race simulations, with the focus on set-up and performance analysis and gathering data on the foiling and handling characteristics in different racing conditions.

The single pilot RaceBird vessel is the brainchild of Norwegian designer Sophi Horne and was co-created together with Brunello Acampora and the expert engineers at Victory Marine and SeaBird Technologies. The RaceBird is powered by a 150 kW Kreisel battery and an outboard motor produced by Mercury Racing, with the boat quickly lifting onto its foils with the benefit of instant torque and acceleration.

E1 organisers also used the opportunity during the test to evaluate different elements of the racing format, including trialling autonomous buoys and cornering profiles, as well as testing the positioning of onboard cameras to be used in the world feed broadcast.

The UIM E1 World Championship was founded by Alejandro Agag and Rodi Basso with a mission to build a new and exciting racing platform on the water, based on future electric technologies to protect and restore our urban waters and coastal areas.

The debut season of the E1 World Championship is scheduled to get underway in Spring 2023. However, fans won’t have to wait long to see the RaceBird flying on the water, with the first public display set to be announced soon.

Alejandro AgagCo-Founder & Chairman of E1, said: “Putting the RaceBird on the water for the first time is a pivotal moment for the E1 World Championship. We’re now one step closer to making electric racing on the water a reality. I remember very well the same scenarios we encountered during the early stages at both Formula E and Extreme E, and just like on those occasions this is a major breakthrough on E1’s journey. Seeing the RaceBird fly proves to me that we can use this exciting, new sporting platform to drive technological innovation in the marine industry and create something spectacular for fans in the cities we visit.”

Rodi BassoCo-Founder & CEO of E1, added: “Seeing the RaceBird flying on the water for the first time was an emotional moment for myself and many others who have been working on this project over the past few months. It’s been a huge team effort to get to this point and it wouldn’t have been possible without the help and support of our partners at Victory Marine and SeaBird Technologies. Special mentions should also go to Kreisel and Mercury Racing for their work on preparing the battery and outboard.

“So far, the RaceBird has exceeded expectations especially with the performance, agility and cornering capabilities. The current performance levels are exactly where we wanted them to be, helping to promote exciting foil-to-foil racing close to the shoreline. In the coming weeks, we’ll continue to run further tests and gather the necessary data. I’m really looking forward to showing it in public for the first time, which we’ll be announcing more on shortly. This test marks the first page of a new chapter in the electrification of the marine industry, focusing on accelerating future technologies for the benefit of our waters.”

Sophi HorneRaceBird designer & Founder of SeaBird Technologies, said: “I’ve been waiting for this moment for almost three years! To finally get to this point is a huge sigh of relief but I’m also very proud of what we’ve managed to achieve with the combined efforts of SeaBird and Victory Marine. Watching the boat being lowered into the water and drive off… that will stay with me for a long time.

“It’s been so amazing to watch my design develop into a fully operational raceboat. We still have some work to do, but for the first round of tests, we really couldn’t have asked for more. With the RaceBird, I wanted to create something unique that stood out from the crowd and got heads turning from an aesthetic standpoint. Seeing it now in motion gliding on the water, I think we’ve managed to achieve that.”

Una pieza de tu tiempo: ¿Qué significa regalarle un reloj a una mujer?

Una pieza de tu tiempo: ¿Qué significa regalarle un reloj a una mujer?

Desde el siglo XVI, los relojes han sido un lujo que tiene mucho más valor sentimental que simplemente dar la hora. Hoy en día, regalar un reloj todavía tiene mucho significado. Si ese regalo es de un hombre a una mujer, es aún más significativo.

Si ha recibido uno de nuestros relojes de lujo de alta gama como regalo del hombre especial en su vida, es posible que se pregunte qué significa. Para ofrecer una idea, hemos resumido solo algunas de las maravillosas razones por las que los hombres han comprado a sus novias, prometidas o esposas un reloj Backes & Strauss.


Los relojes de pulsera han sido un accesorio de moda imprescindible desde que se hicieron populares a principios del siglo XX. Tan pequeños como son, dicen mucho sobre el usuario, y los diseños clásicos pueden complementar incluso al seguidor de la moda más dedicado.

Nuestros relojes han sido diseñados para usarse durante décadas y se vinculan con los gustos cambiantes en el mundo de lo que está de moda. Cuando recibe el reloj perfecto, obtiene el resultado de pensar detenidamente en su gusto y estilo de vida específicos. Con suerte, recibirá un accesorio que complemente su estilo general y lo haga lucir mucho más fabuloso.

Ya se trate de un cronógrafo aerodinámico o de un espumoso reloj de oro rosa con una correa delicada, cada reloj Backes & Strauss tiene un carácter propio. Al igual que tú. La persona que compró su reloj habrá considerado su esencia y su reloj debe expresar esto.


Incluso las suntuosas obras maestras artesanales con incrustaciones de diamantes que creamos son artículos utilitarios. Por muy avanzados que seamos tecnológicamente, ¡la gente todavía necesita relojes!

Es bueno mantenerse organizado, y esto significa llevar un registro del tiempo a lo largo del día. Pero como muchas mujeres pueden estar de acuerdo, no siempre es la tarea más sencilla hurgar en su bolso para encontrar su teléfono celular. Un rápido vistazo a un hermoso reloj en su muñeca es mucho más fácil y mucho más satisfactorio. Además, proporciona un recordatorio sutil pero constante de la persona especial que también le regaló su reloj.


No hay nada que se pueda comparar con abrir un regalo de lujo y Backes & Strauss hace que esta parte del proceso sea especialmente agradable. La suntuosidad de nuestros diseños se extiende a cómo se empaquetan nuestras piezas, ¡y nos aseguramos de que cada segundo que pase con uno de nuestros artículos cuente!

Al igual que las joyas, existe el exquisito suspenso al abrir la caja para revelar lo que hay dentro y luego la pura alegría por la belleza que encuentras. Ya sea un regalo de cumpleaños, un regalo para la temporada navideña o simplemente porque, cuando le regalas un reloj a una mujer, también le estás regalando un símbolo de opulencia y esplendor.


Otra metáfora significativa que entra en juego con un reloj de regalo es la de darle tiempo a alguien. Este es un bien del que todos desearíamos tener más con los que amamos. Alta relojería pueden incluso convertirse en reliquias preciadas, transmitidas a la próxima generación de mujeres poderosas de la familia para marcar hitos importantes. En ese sentido, el fuerte valor sentimental de su reloj no tiene límite de tiempo: debe ser disfrutado por las generaciones venideras.

¡Usar su nuevo regalo puede incluso ayudarlo a llegar más a tiempo! Después de todo, te eleva y te hace lucir más pulido y profesional. Esto contribuye en gran medida a prepararlo para los desafíos que enfrenta todos los días.


No hay nada descartable en el regalo de un reloj. Después de todo, han sido cuidadosamente diseñados para usarse, usarse y disfrutarse todos los días. También son una de las únicas cosas que se pueden usar todo el tiempo y darle a alguien un reloj significa que pensarán en ti más a menudo.

Un reloj de pulsera le recordará a una mujer a la persona que se lo regaló cada vez que se lo ponga, cada vez que lo mire durante el día o la noche. Y luego, una vez más, cuando se lo quita antes de ducharse, bañarse, nadar o para descansar bien por la noche.

Para las parejas comprometidas, los relojes pueden ser un regalo poético y romántico que simboliza el tiempo que pasan juntos. Los relojes clásicos son ideales como regalo de aniversario, ya que representan el pasado, el presente y el futuro. Un hombre que te da este tipo de regalo te está comunicando la profundidad de su compromiso y su afecto permanente por ti.

Si aún no estás prometida y has recibido algo de este calibre del hombre de tu vida, casi siempre significa que está comprometido contigo. Significa la profundidad de su relación y consolida la idea de que le gustaría compartir cada segundo, minuto y hora juntos.


Lo que hace que el reloj de pulsera perfecto sea un regalo ideal para las mujeres es el hecho de que se necesita tanto cuidado y atención para elegirlo. No solo atesorarás la excelencia artesanal que define nuestras piezas, sino también su significado personal. Te dice que el dador valora tus deseos y necesidades y profundiza tu relación con el reconocimiento de tu individualidad.

El regalo del reloj de pulsera muestra que se ha pensado mucho en el presente y que el donante está interesado en ti y quiere saber lo que te gusta. Tan complejo como es este proceso, es la simplicidad misma y es evidencia de una conexión profunda y duradera entre dos personas.

Dar algo tan personal y significativo como un reloj de pulsera Backes & Strauss requiere que el donante haga un riesgo calculado porque tiene que entenderte para comprarte algo que te encantará. Es una forma de establecer un lazo emocional aún mayor entre una pareja y se trata de que tu amado tome un papel más activo en tu vida.

Se pueden atribuir muchos significados literales y figurativos a la entrega de un reloj como regalo. Pero al final del día, depende de ti descifrar cuál es la intención detrás de esto. Sin embargo, es una suposición bastante segura que si alguien se ha tomado el tiempo para tratar de averiguar qué tipo de reloj se adapta mejor a usted y sus necesidades; ¡ha sido alcanzado por la flecha de Cupido!

Fusion under the influence – With Chiara, everything is possible

Chiara Ferragni has joined the Hublot family in the company of many legendary personalities such as football legend Pelé, tennis world No. 1 Novak Djokovic, track and field champions Dina Asher-Smith and Usain Bolt and three Michelin star chef Clare Smyth. She lights up everything she touches and creates, she is a natural-born winner and shines her aura over everything she loves and chooses.

Today, she has chosen Hublot. So why Chiara Ferragni and why Hublot?

Everything I do, I do to share. The things I love, the people I love, the things I experience, my daily life, my children, my work: I put my heart into everything to inspire others, to believe in themselves and their dreams. I found my ikigai in 2009. I managed to combine my passion with my talent in response to a need and now it has become my business. By opening the door to who I am and what I experience, I am also hoping to inspire the women of today not to choose between being a wife, a mother or an entrepreneur. All these roles complete me, just as they complete each other. Beauty drives everything I do. Not only inner beauty, but everything I see around me. That is reflected in my collaborations, my words, my charity work and my daily life. Why Hublot? Because Hublot is not like any other watch brand, it follows its own distinctive path, with determination: It follows its dreams of innovation, while respecting traditions; it seeks beauty both inside and out, by showcasing much more than athletic performance or the success of a family member, it celebrates the reasons for this performance and success, in other words, the ability to be first, different and unique. Hublot’s messages and values speak to me, that’s why I have chosen to join this family today. A fusion of passion and determination has shaped who I am, across all my roles, and forged the businesswoman I have become. This same fusion has also made Hublot the company it is today.

Chiara Ferragni
Hublot Brand Ambassador

Who does not know Chiara Ferragni? Her extraordinary destiny is not down to luck, this visionary and determined woman is someone who learnt how to grow and evolve with her time. By portraying and sharing who she is and what she loves, she has realised her dream, inspiring the men and women of her generation to believe that anything is possible. As someone who is both authentic and spontaneous, she has turned her happy, positive and generous nature into her trademark. As a visionary and pioneer, she has been able to move with the times by dominating the digital platforms and turning her passion into a real business. Her passion became her job, and her natural talent transformed into a success that is seemingly within everyone’s reach. Her inspiring journey proves that anything is possible; it’s the stuff of dreams, while being very real. Who wouldn’t want to live and realise their dreams like Chiara Ferragni? At Hublot, we love inspiring women and men who believe in their dreams and move heaven and earth to fulfil them, who assert their distinctive personality, are willing to go out on a limb, who are not afraid of what people will say and who follow their path with authenticity and passion.
That’s why Chiara fits so well into our family.

Ricardo Guadalupe HUBLOT CEO

Surely, one no longer needs to present Chiara Ferragni?

Well yes, if only to highlight the very nature of this woman, a so-called influencer, a term too small to encompass all her talents. As a business woman, entrepreneur, influencer, wife and mother of two, she embodies that ‘can do’ attitude that everyone finds so inspiring.Twelve years after launching theblondesalad.com, Chiara Ferragni has achieved a success story. When she started out, Instagram did not exist and blogging was in its infancy. It took Chiara only a few months to turn a hobby into a business, attracting the attention of the media and the fashion world, and placing her name alongside the biggest luxury brands.

First, Unique, Different. Just like Hublot! She single-handedly created a job for herself, followed her instincts, asserted her choice to share and talk about her life. Honoured several times by Forbes, her career path has even inspired a study by the prestigious Harvard University to understand her success.

In tune with her times, Chiara is leaving her mark on the world. She resolutely believes in her dreams. A dreamer she may be, but she is firmly rooted in her land and her roots. Chiara Ferragni draws her strength from the stability of her family, her parents and two sisters; she has gone on to recreate this strength through her own family, which she has built with Fedez.

So, is it natural talent, intuition or destiny? What if was a bit of all three? Whatever the case, what is certain is that she achieves firsts with her writing, she asserts her uniqueness, and her difference while retaining that very inclusive feeling of being the ‘girl next door…’

She is an entrepreneur who embodies the digital revolution and the arrival of social media. Chiara is a pioneer, she is constantly achieving firsts. With her fashion blog, launched 12 years ago, she was immediately considered the most influential and most famous blogger in the world. She created her own brand of shoes, then clothing in 2015— Chiara Ferragni Brand, —she was also the first to be listed as the world’s most powerful influencer. Indeed, there is no shortage of superlatives to describe her career and she is not afraid to use them. Both her real life and her digital world are filled with sharing, joy, values and optimism. She is unique, that’s for sure! She is proud of her uniqueness, after transforming her name into a brand, a trademark, a style and an inspiration. She also uses her platforms and visibility to help the causes that are close to her heart. Ultimately, what makes her different is that she has managed to turn her passion, her daily routine and her life into a true success story. She is also different for resembling a generation of women who live with the times and manage to combine several roles, without placing any filters between the different parts of their lives. With an Instagram community of 24.7 million followers, she shares her daily life as a wife, mother and entrepreneur openly and frankly. Chiara is an inspirational figure.
Chiara and Hublot, how it began

You may remember the pictures of Chiara Ferragni wearing the Big Bang Millenial Pink. A unisex watch with an inclusive message, produced as a limited edition of 200 pieces in a shade chosen by Lapo Elkann and designed in collaboration with Garage Italia. Since this project, Chiara and Hublot have simply understood that there were many similarities between their worlds.
So, get ready, because what Chiara & Hublot are preparing for you is likely to make a big impression, once again… First, Unique, Different!
