Blancpain Fifty Fathoms 5100B-1110-B52A 38 mm Grey Dial

The Fifty Fathoms 5100B-1110-B52A gives the dive-watch formula a 38 mm stainless-steel case, only 10.8 mm thick. Its grey sunburst dial, textile strap and 300-metre rating give the compact case a clear diving purpose, while the measured proportions keep the profile neatly controlled. The date sits within a format that remains recognisably Fifty Fathoms without relying on scale alone.

Automatic calibre 1150 uses Blancpain's 1100-family twin-barrel platform and stores 100 hours of power. It measures 26.2 mm across and 3.25 mm high, with 28 jewels and 210 parts at a frequency of 21,600 vph. A central 18 ct gold rotor with NAC coating is visible through the sapphire back, adding a refined movement-side counterpoint to the functional case.
