Blancpain Fifty Fathoms Automatique Steel 45mm Blue Dial 5015D 1140 52B - BRAND NEW

The Blancpain Fifty Fathoms Automatique is widely regarded as the world's first modern scuba diving watch, introduced by Blancpain in 1953 and purpose-designed to meet the demanding requirements of military combat divers. Over seven decades the Fifty Fathoms has evolved without abandoning its founding principles: a large, legible dial, a unidirectional rotating bezel for elapsed-time tracking, robust water resistance, and an automatic movement housed in a case substantial enough to command respect on any wrist. Today the collection remains the definitive statement of Swiss diving watchmaking at the highest level.

Reference 5015D-1140-52B is the Fifty Fathoms Automatique in a 45mm stainless steel case — a diameter that honors the watch's original large-tool-watch proportions and ensures exceptional dial presence whether worn over a wetsuit or with a tailored cuff. The case is crafted in polished and satin-brushed steel, the interplay of finishing surfaces adding visual depth that rewards close inspection. At 45mm this is a watch that wears with authority, yet Blancpain's careful ergonomic shaping keeps it surprisingly wearable on a wide range of wrist sizes.

The dial is rendered in a rich blue tone and populated with index hour markers rather than numerals, giving the watch a clean, contemporary sophistication while maintaining the high-contrast legibility that defines a serious dive instrument. Applied luminous indices and hands ensure readability in low-light or underwater conditions. The overall aesthetic sits comfortably between serious tool watch and luxury dress piece — a duality that has always defined Blancpain's approach to sport watchmaking.

Perhaps the most distinctive design element of this reference is its sapphire crystal bezel. Where many dive watches employ ceramic or aluminum bezels, the sapphire version offers remarkable scratch resistance and a jewel-like translucency that catches light in a uniquely luxurious way. The unidirectional rotation of the bezel upholds the functional dive-watch mandate — a diver can only rotate it one way, ensuring that elapsed bottom time can never be accidentally extended. The rubber strap is both practical and refined, complementing the blue dial and offering the secure, comfortable fit essential for active water use.

Powering the 5015D-1140-52B is an automatic movement, consistent with the Fifty Fathoms line's commitment to mechanical self-winding calibers that are entirely in keeping with Blancpain's manufacture philosophy. Blancpain produces movements in-house at its Le Brassus manufacture and is among the most respected movement makers in Switzerland, ensuring that the mechanism inside this watch meets the exacting standards the brand is known for. Buyers can wear this reference with full confidence in its long-term reliability and serviceability.
