Discover MB&F's precision with the Horological Machines (ref. 70.PBL.B), an elegant watch engineered for daily versatility and long-term reliability. From profile to crystal, the architecture convinces: crafted in platinum and measuring 53.8 mm in diameter, with a thickness of 21.3 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel.

Up close, the dial rewards inspection: a skeleton tone with matte finish, executed in aluminium, framed by arabic numerals hour markers, and proprietary hands. Inside, precision takes center stage: the HM7 caliber. Released in a constrained run, appealing to focused collectors. First released in 2018. 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.
