The H. Moser & Cie. Perpetual Calendar is considered to be one of the most legible and easy to set on the market, as it can be adjusted both forwards and backwards at any time of day. With the Endeavour Perpetual Calendar Concept Tantalum model, the manufacture explores a new facet of tantalum, adopting this rare and exacting metal for the case but also for the dial, machined from solid and featuring a brushed sunburst pattern. No lacquer, no surface treatment, no artifice. A Perpetual Calendar reduced to the essentials, where raw metal and mechanical ingenuity speak for themselves, with only 50 pieces produced.
