Moser & Cie., a symbol of sophisticated minimalism, and Studio Underd0g, a bold and creative brand, have come together to create two watches that go far beyond mere timekeeping. Here are the details of this remarkable collaboration that gave birth to the Endeavour Perpetual Calendar Passion Fruit and the 03SERIES Passi0n Fruit.

Two Watches, One Shared Passion

Moser & Cie. perfectly reflects the brand’s signature minimalism, while adding a touch of originality with its Purple lacquered dial and Maracuja “Grand Feu” enamel. Limited to just 100 pieces, this watch combines sophistication with simplicity, reminding us that elegance often lies in the most subtle details. The hammered 18-carat yellow gold dial and the green accents on the central hand and feeler embody the passion shared by watch enthusiasts.

The 03SERIES Passi0n Fruit from Studio Underd0g, on the other hand, stands out with its Coarse Dégradé Amber and Royal Purple dial, a true explosion of color and vitality. Equipped with a mono-pusher cam chronograph movement, it demonstrates that horological excellence can also be synonymous with boldness and creativity.
A Collaboration Rich in Color and Meaning
These watches are not only remarkable for their exceptional aesthetics but also for the story they tell. H. Moser & Cie. and Studio Underd0g have created more than just timepieces; they have crafted works of horological art, each with its own identity, yet harmoniously complementing each other. The green accent present on each model symbolizes the passion that drives all watch enthusiasts, a subtle yet powerful nod to this fusion of tradition and innovation.
