Introducing H. Moser & Cie Endeavour (ref. 1804-0200), a distinctive model that balances proportion, precision, and presence. On the wrist, the case feels purposeful: crafted in stainless steel and measuring 42 mm in diameter, with a thickness of 11.6 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire. Visually, the face is where character emerges: a blue tone with sunburst finish, framed by none hour markers, and feuille hands. Among collectors, it is nicknamed "Concept". Mechanically, the watch prioritizes accuracy: the HMC 804 caliber. Produced in limited numbers, appealing to focused collectors. First released in 2017. The silhouette offers presence without excess, lending confidence in a range of situations. Finishing showcases disciplined attention to detail across facets, edges, and surfaces. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
