The San Martin SN0128-G BB58 is a professional-grade 40mm automatic diving watch designed for enthusiasts who value both refined aesthetics and rugged reliability. Inspired by classic diver silhouettes, this watch is powered by the trusted NH35 automatic mechanical movement, delivering accurate timekeeping and a 41-hour power reserve.
The 316L stainless steel case is complemented by a brushed Jubilee 5-link bracelet with an adjustable clasp, ensuring comfort and durability. A scratch-resistant sapphire crystal with AR coating enhances dial clarity, while the unidirectional ceramic bezel with luminous pip provides functionality for underwater timing.
Legibility is at the heart of the SN0128-G, featuring BGW-9 blue luminous coating on snowflake hands and markers for superior visibility in low-light conditions. Rated to 200 meters (20 Bar) of water resistance with a screw-down crown and case back, this model is built for real diving yet versatile enough for everyday wear.
Available with black or red ceramic bezels, and dials featuring San Martin’s hexagon logo in rose gold or white, this timepiece delivers a balance of sophistication and adventure.
