Blancpain Fifty Fathoms Automatique 5015-12B40-O52A

The reference that re-launched modern dive watch royalty — Blancpain's Fifty Fathoms Automatique in a 45mm titanium case with a stunning sunburst blue dial and matching blue sapphire bezel. Light on the wrist, serious in spec (300m water resistance), and absolutely legendary in lume — this is the modern Fifty Fathoms at its most wearable and most collectible. Presented in excellent pre-owned condition as a full set with original outer box, inner Pelican-style dive case, Diver's Logbook, watch roll, booklets, and warranty card. 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. 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.  This watch is a 2024 model and original MSRP was $22,800.
