Introducing MB&F Horological Machines (ref. 56.STRL.B), an elegant watch engineered for daily versatility and long-term reliability. From profile to crystal, the architecture convinces: measuring 46.8 mm in diameter, with a thickness of 20.7 mm, defined by a round silhouette, protected by dlc coating. The caseback is open, and the crystal is sapphire, delivering water resistance to 3000 meters. Up close, the dial rewards inspection: a black tone, framed by arabic numerals hour markers, and proprietary hands. Inside, precision takes center stage: the HMX caliber. Released in a constrained run, appealing to focused collectors. First released in 2015. Designed for real-world wear, the watch transitions smoothly from tailored looks to casual settings. Manufacturing tolerances and surface treatment highlight consistent quality control. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
