No matter how recognisable a watch may be, the brand will invariably add its name and logo. Not H. Moser & Cie. For its Concept versions, the Schaffhausen firm chooses to leave its dials empty of any inscription... no less a way of distinguishing each one. The Endeavour Tourbillon is a case in point. Nothing distracts us from the flying tourbillon, visible at 6 o'clock. Inside the white gold case beats the Manufacture's latest proprietary movement, the HMC 804. Timekeeping precision is ensured by a double flat balance spring that is also developed and manufactured in-house. Note that the tourbillon's design as an interchangeable "plug & play" module allows easy servicing.
