Atelier Wen and Massena LAB bring Chinese design and Swiss decorative craft together in a tantalum collaboration with plenty to say
Everyone knows the story of MB&F—and how the “F” in the name refers to “Friends”. Founder Max Büsser applied the same formula that made the Opus series a success during his time at Harry Winston to his own brand: collaborate with talented watchmakers to create radical timepieces. That spirit of creative exchange has been at the core of MB&F since its inception.

The whole premise makes a lot of sense. Put two or more highly creative minds together, free from the constraints of legacy and bureaucracy, and the result can be something truly extraordinary. As independent watchmaking has grown in prominence, this inclusive approach has spread across the industry. Recent examples include Louis Erard and Konstantin Chaykin, Behrens and Vianney Halter, and Christopher Ward and Studio Underd0g. The resulting timepieces have captured the imagination of collectors and enthusiasts alike, creating greater demand for such partnerships.

Atelier Wen, a watch brand established in China with a French soul, keeps the momentum going with its partnership with Massena LAB, a creative horological studio, on a special edition of the Inflection. Atelier Wen’s groundbreaking Inflection is the first non-limited watch collection whose case and bracelet are crafted in tantalum, a metal notoriously difficult to machine.
Unveiled at the recent Geneva Watch Days, the Atelier Wen x Massena LAB Inflection Shuò features Swiss-made dials with intricate hand-tremblage engraving on solid 18k gold, a first for Atelier Wen.
One of the most demanding traditional decorative crafts in watchmaking, tremblage is created by working a graver across the surface in a continuous trembling motion. It is an incredibly meticulous process requiring confident, steady hands, resulting in a finely textured, frost-like surface. The task was entrusted to hand-engraving specialist Coralie Mercier of GT Cadrans, a Swiss company specialising in high-end watch dials.

The Inflection Shuò comes with two dial variants: white gold (limited to 10 pieces) and rose gold (limited to 40). The layout recalls a California dial, but instead of the traditional mix of Roman and Arabic numerals, it uses Arabic numerals from 10 to two o’clock and Chinese calligraphy from four to eight o’clock. The outer ring is finely engraved with the classic Chinese huiwen border. Blued-steel hands add an elegant touch to the Sino-Swiss aesthetic.
Like its predecessors, the Inflection Shuò is powered by a Girard-Perregaux movement, complete with a striking wind-inspired rotor in 5N rose gold.
“The dial took us into an entirely new territory with the tremblage,” exclaims Robin Tallendier, co-founder of Atelier Wen. “This collaboration has pushed us to think differently about how our design language can co-exist with Swiss decorative traditions. The result is a watch where every element is in genuine conversation with one another.”
Tallendier points out that the Inflection Shuò may be the most literal expression yet of the brand’s Franco-Chinese ethos. “Chinese calligraphy and decorative motif sit alongside Swiss finishing and movement, housed in a tantalum case whose curves are derived from Chinese architectural forms. What [this watch] does is make the East-meets-West dialogue more explicit than ever before.”

Massena LAB founder William Massena adds: “This is the first Atelier Wen wristwatch to feature a dial made in Switzerland. As with all our collaborations, the goal was to design and develop a watch that would reflect the philosophies and aesthetics of both collaborators, and we’re incredibly happy with the result.”
Massena was keen to collaborate with Atelier Wen after visiting the latter’s workshops in China. “He saw that China could deliver the highest level of contemporary watchmaking,” says Tallendier.
For Massena, the partnership was also a chance to add a Chinese dimension to a portfolio of largely Western collaborations that has so far included Vianney Halter, Studio Underd0g, Angelus and Raúl Pagès. “Plus, I’m especially excited to offer our collectors a Massena LAB watch in tantalum, one of my favourite metals,” he quips.

The release of the Inflection Shuò is bound to attract considerable attention from collectors. Asked how a collaboration like this fulfils expectations of authenticity and well-made timepieces, Tallendier says: “For us, authenticity comes from making sure every detail [on the watch] has a reason to exist. The dial isn’t decorated to appear merely artisanal. The value of the piece lies in the human skill, the time and the thought that go into making it.”

He believes such collaborations can only benefit both makers and collectors. “The most interesting watches today are often the result of genuine creative exchange, where the question asked is not where they are made but why, by whom and at what level of conviction,” he adds.
Collaborations are always exciting, but more importantly, they are crucial to sustaining the industry’s creative momentum. “They keep exceptional crafts alive. They also build communities across borders. The watch exposes Atelier Wen collectors to Massena LAB, and vice versa, expanding the audience for independent watchmaking as a whole. In a market dominated by large groups, this kind of cross-pollination isn’t just valuable—it’s vital,” says Tallendier.
