The Endeavour Perpetual Calendar Concept Tantalum can be adjusted both forwards and backwards at any time of day.  Tantalum is not used solely for the case; it also constitutes the dial, machined from solid and featuring a brushed sunburst pattern.  Machined from a tantalum plate, the latter features a brushed sunburst pattern applied directly on the material. No surface treatment. No lacquer. No varnish. Nothing obstructs the view of the metal. The result is raw, deep, almost mineral, a living dial whose reflections vary subtly depending on the angle, revealing the true nature of the material rather than a mere decorative effect. The leaf-shaped hour and minute hands are made from steel and contrast beautifully with the dial.

Including this model in its Concept series, H. Moser & Cie. has stripped away anything superfluous: no logos, no indices, no graduations. Only the essential indications remain: the instantaneous jump big date, a signature of the Moser Perpetual Calendar, combined with the power reserve indicator at nine o’clock, displaying the movement’s seven-day power reserve. In the center, the small hand indicating the months. Nothing more. Nothing less.  At the heart of the watch beats the HMC 800 hand-wound manufacture movement. All adjustments are made via the crown.
