Blancpain Fifty Fathoms Automatique Steel 42.30mm Sunburst Black Dial 5010 1130 71S - BRAND NEW Blancpain Fifty Fathoms Automatique Steel 42.30mm Sunburst…

The Blancpain Fifty Fathoms is one of the most consequential watches ever made, born in 1953 as a purpose-built instrument for professional divers at a moment when no true standard for the category yet existed. Conceived in collaboration with the French Navy's combat diving unit, the original Fifty Fathoms established the blueprint that every serious dive watch since has followed: a rotating timing bezel, a screw-down crown, a legible high-contrast dial, and an automatic movement sealed against depth. Blancpain's Le Brassus manufacture has honored that legacy across decades, and the Fifty Fathoms Automatique continues to carry the lineage with integrity and without compromise.

Reference 5010-1130-71S sits firmly within the modern Fifty Fathoms Automatique collection, presenting the collection's signature proportions in a 42.30mm stainless steel case. The dimensions are true to the spirit of the original — substantial enough to convey instrument-grade seriousness on the wrist, yet refined in execution so that the watch wears with surprising elegance in non-aquatic contexts. The brushed and polished finishing on the steel case and bracelet reflect the dual identity of the Fifty Fathoms as both tool watch and luxury object.

The dial is one of the most visually arresting elements of this reference. A deep sunburst black surface shifts in light from near-matte charcoal to a rich, luminous black depending on the angle, giving the watch a sense of dimensionality that flat-lacquered dials simply cannot achieve. Index markers and Arabic numerals are applied with precision and generously coated with luminescent material, ensuring legibility in conditions ranging from bright sunlight to the darkness of depth — exactly what the Fifty Fathoms was always designed to deliver.

The bezel on the 5010-1130-71S is among the most distinctive details in the entire dive watch market: a unidirectional rotating bezel set with a sapphire crystal insert rather than the more common ceramic or aluminum. Sapphire offers extraordinary scratch resistance and a visual transparency that allows the bezel's structure and markings to read with a clarity and depth unmatched by conventional materials. This single design choice elevates the 5010-1130-71S above nearly all of its category peers and makes it immediately identifiable to those who know the line.

Powering this watch is an automatic movement, as the Automatique designation confirms, providing the convenience of self-winding wear and the assurance of Blancpain manufacture quality. Blancpain has long been a vertically integrated manufacture, producing its own movements in Le Brassus, Switzerland, and the caliber within the Fifty Fathoms Automatique line is built to the standards one expects from one of haute horology's most respected names — robust, accurate, and finished to a level rarely visible through a display caseback but always present in the movement's behavior on the wrist.
