H. Moser & Cie Endeavour Perpetual Calendar Concept - Limited Edition - 42 MM - Tantalum - Sunburst Tantalum Dial - Leather Bracelet - 1800-2004

H. MOSER & CIE ENDEAVOUR PERPETUAL CALENDAR CONCEPT LIMITED EDITION

VERY RARE

The Endeavour Perpetual Calendar Concept Tantalum pushes one of H. Moser & Cie's most emblematic complications to its purest expression. Known for its clarity and ease of use, the Moser perpetual calendar was stripped of all superfluous elements: no logo, no indices, no distraction. Just essential information, rendered in a rare and demanding material. Limited to 50 pieces.

Tantalum is a dense, rare metal, exceptionally challenging to machine and requiring precise control at every stage. In return, it reveals a distinctive presence: a deep grey tone animated by subtle bluish reflections that shift with the light. Here, it extends beyond the case to become the dial itself, machined from solid metal and sunray-brushed directly into the surface. No lacquer, no coating, no treatment, nothing stands between the material and the eye. Just the metal, and everything it has to say.

At its heart beats the manufacture hand-wound calibre HMC 800, featuring a minimum seven-day power reserve and a double hairspring for enhanced precision. Through the caseback, the movement reveals its inner workings and the discreet leap year indicator. Technical complexity at the highest level, expressed with absolute restraint.
