Experience the craft of Blancpain in the Fifty Fathoms (ref. 5200-0240-NAOA), an elegant watch engineered for daily versatility and long-term reliability. From profile to crystal, the architecture convinces: crafted in ceramic and measuring 43.6 mm in diameter, with a thickness of 15.25 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel. The caseback is open, and the crystal is sapphire, delivering water resistance to 30000 meters. Up close, the dial rewards inspection: a blue tone, framed by mixed hour markers, and baton hands. Inside, precision takes center stage: the F385 caliber. Initial production year: 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.
