Meet H. Moser & Cie Henry (ref. 5901-0301), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in platinum and measuring 38.9 mm in diameter, with a thickness of 11 mm, defined by a rectangular silhouette. The caseback is open, and the crystal is sapphire. At a glance, the dial balances texture and clarity: a black tone with gloss finish, framed by none hour markers, and feuille hands. At its heart beats a proven engine: the HMC 901 NHM caliber. Introduced in 2019. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
