Technical Description

The 45mm grade-23 titanium case keeps the watch surprisingly light on the wrist despite its commanding presence, with brushed surfaces, polished accents, and the unmistakable curved Fifty Fathoms lug profile. A unidirectional rotating bezel with a domed blue sapphire insert tops the case, with luminous markers integrated directly into the sapphire — a hallmark detail of the reference. The sunburst blue dial catches the light dramatically, with applied Arabic numerals at 12, 3, 6, and 9, large luminous indices, sword-style hands, and a discreet date window at 3 o'clock. "Fifty Fathoms 300m/1000ft" sits above the 6, and the lume on this dial and bezel is famously one of the best in production — the night shot speaks for itself.


Through the sapphire caseback you'll find Blancpain's automatic in-house movement, signed and serialized, finished with the engraved "Fifty Fathoms" rotor signature. The watch is fitted to a navy canvas-style strap with matching tonal stitching, a Blancpain-signed titanium pin buckle, and the brand's signature embossed inner lining — a comfortable, modern presentation that complements the all-blue colorway perfectly.
