H. Moser Endeavour Perpetual Calendar Tantalum Blue Enamel Debuts Rare Metal Construction

H. Moser & Cie. recently released the newest model in its Endeavour Perpetual Calendar timepiece line. Using a Tantalum and steel construction, this is the first watch from the esteemed watchmaker to use the rare metal.

Tantalum, first discovered in 1802, is a very dense, malleable, and durable heavy metal with corrosion and acid resistance properties. And the watchmaker’s Endeavour Perpetual Calendar Tantalum Blue Enamel reference 1800-2000 is the latest to incorporate the metal with its complication.

The 42mm-wide and 13.1mm-thick Endeavour Perpetual Calendar Tantalum Blue Enamel features dark material with bluish reflections for its iconic minimalist case design. The dial features a ripple textured Abyss Blue fumé ‘Grand Feu’ enamel, pared-down indices and details on the dial to only the 12 and 6 o’clock hour-markers, brightly polished leaf hour and minute hands, small tapered hand between them for the month, a 6 o’clock running seconds subdial, a power reserve indicator at 9 o’clock, and a 3 o’clock date window that makes an instant date change at midnight. The watch comes with a soft gray matte kudu leather strap.

The watch is powered by the HMC 800 hand-wound perpetual calendar movement. Like most of the line’s movements, the complication is visible through the case back and sports Côtes de Genève across the main bridges, and gold-filled H. Moser & Cie. shield emblem engraving. The HMC 800 has a 168-hour power reserve and beats at 18,000 BPH.

The Endeavour Perpetual Calendar Tantalum Blue Enamel retails for $82,500 and is available now through authorized dealers. Check out Moser & Cie.’s official website for more information.
