Blancpain 5100B Bathyscaphe SS Grey Dial

This Fifty Fathoms Bathyscaphe Ref. 5100B‑1110‑B52A embodies Blancpain’s unparalleled mastery of diving heritage and refined elegance. Housed in a satin‑brushed 38 mm steel case introduced in the mid‑2010s, it powers forward with the in‑house automatic Caliber 1150 delivering an impressive 100‑hour power reserve and showcasing a silicon balance spring for precision and durability. The sunburst meteor grey dial, inspired by the cosmos, is matched with a uni‑directional ceramic bezel and Liquidmetal hour markers, offering exceptional legibility and subtle artistry. Water‑resistant to 30 bar (approximately 300 meters), it remains true to the Fifty Fathoms’ professional dive origins while maintaining a polished demeanor suitable for everyday wear. The sail‑canvas strap with rubber backing and pin buckle reinforces its technical capability without sacrificing comfort. Collectors prize this reference for its balanced proportions, robust movement architecture, and its embodiment of Blancpain’s quiet innovation—a diver that delivers in both performance and proportion.
