Housed in a formidable 48 mm brushed titanium case, the watch remains lightweight yet exceptionally durable, ideal for professional divers and seasoned explorers. The deep black dial is outfitted with oversized luminous Arabic numerals, bold hands, and a red-tipped GMT hand that enables easy tracking of a second time zone — a rare and practical feature in high-depth dive watches.

Its unidirectional bezel with a luminous black sapphire insert and a clear, legible dial make it a true professional instrument. Produced as a limited edition, the 500 Fathoms GMT is as collectible as it is capable. It is fitted with a rugged yet refined black sail-canvas strap with a matching titanium folding clasp, ensuring comfort, durability, and secure wear during underwater missions or global travel. This rare model blends Blancpain’s legacy in precision watchmaking with modern performance, standing out as a unique and powerful tool watch for connoisseurs and adventurers alike.
