H. Moser & Cie Endeavour Perpetual Calendar Concept Tantalum - (Ref. 1800-2004) Product Details

At H. Moser & Cie., the Perpetual Calendar is not a demonstration. It’s a given. Legible, intuitive and adjustable both forwards and backwards at any time of day, it has transformed a complication once considered elitist into a common-sense horological object. With the Endeavor Perpetual Calendar Concept Tantalum model, the brand has pushed this minimalist approach even further: the same iconic complication, the same mechanical rig our, but this time stripped of all artifice. On the Endeavor Perpetual Calendar Concept Tantalum, the metal is not used solely for the case; it also constitutes the dial. 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.
