H. Moser & Cie. ENDEAVOUR Perpetual Calendar Black Golden



A titanium case with polished DLC finishing is the armour protecting this exceptional solid gold movement and dial. In a very rare combination, exemplary of traditional watchmaking craftsmanship with a fresh new approach, H. Moser & Cie. introduces the Endeavour Perpetual Calendar Black Golden Edition in a series limited to only 10 pieces. The HMC 341 manufacture calibre housed within this watch is a sophisticated execution of the ingenious perpetual calendar movement (winner of the Grand Prix de Genève for a complicated watch), with solid gold plates and bridges, hand-engraving and a Moser escapement with the Straumann Double Hairspring®.  

Building on the exceptional qualities of the Perpetual Calendar, this unconventional watch combines a strong, scratch resistant material for the case to house a special H. Moser movement. Set with solid gold plates and bridges, this movement houses a Moser escapement with the Straumann Double Hairspring® and two functional diamond end-stones, chosen for the clear colour they lend to the final design. Double barrels set below two screwed golden chatons enable a minimum 7-day power reserve, indicated by the display on the dial at 9 o’clock. The colours of the gold fumé dial with a sunburst pattern flow from a warm gold to shaded fumé tones that blend into the dark polished titanium case. Punctuated by the Perpetual Flash Calendar at 3 o’clock, the dial has a noticeably large date window with golden numerals. This calendar may be adjusted forward and backward, at any time – an exceptional ability for a perpetual calendar – making it very easy to use. To set the perfect finish, a limited-edition elegant Macassar wooden box accompanies this masterpiece that is available from July 2014.
