Steeldive SD1953 40.5mm Sapphire Diver Watch – NH35

Precision Crafted for the Modern Explorer

The Steeldive SD1953 is a refined dive watch that blends professional-grade performance with understated elegance. Powered by the legendary Japan NH35 automatic self-winding movement, this 40.5mm timepiece is built for those who demand both style and substance — whether on the ocean floor or at the dinner table.

Encased in polished 316L stainless steel and protected by a scratch-resistant sapphire crystal, the SD1953 exudes quiet confidence. The unidirectional ceramic bezel and luminous Arabic numeral markers ensure legibility in any light, while the BGW9 blue luminous treatment adds a captivating glow in low-light conditions. Rated to an impressive 300M / 30 ATM, this watch is as capable as it is beautiful.

Available in multiple bracelet configurations — including a premium milled clasp stainless steel bracelet — the SD1953 is a versatile companion that transitions effortlessly from adventure to everyday wear.
