Discover Blancpain's precision with the Fifty Fathoms (ref. 5100-1140-O52A), a distinctive model that balances proportion, precision, and presence. On the wrist, the case feels purposeful: crafted in stainless steel and measuring 38 mm in diameter, with a thickness of 10.77 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. Visually, the face is where character emerges: a blue tone, framed by stick / dot hour markers, and baton hands. Mechanically, the watch prioritizes accuracy: the 1150 caliber. First released in 2013. 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.
