ntroducing a dynamic duo: the Endeavour Perpetual Calendar Passion Fruit by H. Moser & Cie. and the 03SERIES Passi0n Fruit by Studio Underd0g. These timepieces are not just about telling time, they’re about making a statement, blending elegance and innovation with a dash of playful rebellion.

The Endeavour Perpetual Calendar Passion Fruit showcases H. Moser & Cie.’s signature minimalism and complex simplicity, powered by their acclaimed star calibre. On the flip side, Studio Underd0g 03SERIES Passi0n Fruit features a Swiss-cam operated mono-pusher chronograph movement, a bold new venture for the brand, proving that one should never underestimate the underdog.

“Our collaboration is fuelled by a shared passion - a passion for crafting timepieces that are not just functional, but truly artistic,” says Edouard Meylan, CEO of H. Moser & Cie. “Together with Studio Underd0g, we’ve embarked on a journey to celebrate the beauty and joy of horology, creating a fun and an unforgettable experience for collectors.”

These watches are more than accessories; they’re expressions of individuality. Each piece stands out on its own yet complements the other, offering wearers the choice of sophistication with the Endeavour Perpetual Calendar Passion Fruit or a vibrant edge with the 03SERIES Passi0n Fruit, yet always knowing the two pieces are inherently linked.

Bursting with bold, acid colours, the designs reflect the lively energy and creativity that define both brands. The Endeavour Perpetual Calendar Passion Fruit features a striking combination of a purple lacquered sunburst dial and a Maracuja “Grand Feu” enamel dial on an 18-carat yellow gold base with a hammered texture. Meanwhile, the 03SERIES Passi0n Fruit boasts a Coarse Dégradé Amber and Royal Purple multilayer dial, striking a perfect balance between elegance and exuberance. Both watches, devoid of logos, remain unmistakably distinctive - a true testament to their unique design and craftsmanship.

A touch of green on each timepiece symbolizes the seed of passion that flourishes within every watch enthusiast, a subtle yet powerful nod to the legacy of innovation and creativity.

Limited to just 100 pieces, this collaboration also marks the first time Studio Underd0g has partnered with any other watchmaker, further underscoring the significance of this collaboration. “We are thrilled to work with H. Moser & Cie. on this milestone collaboration,” says Richard Benc, founder and CEO of Studio Underd0g. "By leaning into our shared values, we have been able to create something truly exceptional.”

The H. Moser & Cie. x Studio Underd0g collaboration is a vibrant celebration of the passion, creativity, and maverick spirit that drives the world of watchmaking, honouring the dedicated communities that inspires us all.
