H. Moser & Cie Tantalum Endeavour Perpetual Calendar Watch 42Mm

The HMC 800 calibre at the centre of the Tantalum Endeavour Perpetual Calendar watch is impressive - making the calendar mechanism an integral part of the movement - but it's the materials that H. Moser &, Cie. uses that steal the show. The case is crafted from tantalum, a metal renowned for its difficulty to machine and polish, while the distinctive texture of its dial is the result of the ancestral technique of grand feu enamelling.
