Black Automatic Dive Watch 40mm

San Martin presents a professional-grade automatic dive watch engineered for reliability and style. The NH35 movement delivers precise timekeeping with smooth, mechanical operation visible through the exhibition caseback. At 40mm, the case strikes a balanced proportion suitable for most wrist sizes while maintaining the presence expected of a true dive instrument. Water resistance to 20 bar (200m) ensures confidence in freshwater and shallow diving environments. The sapphire crystal resists scratches and maintains clarity through years of wear. Luminous hands and indices—available in BGW9 lume—provide visibility in low-light conditions, whether underwater or in dim settings. The robust construction combines durability with refined aesthetics. Choose between the classic black dial or explore the SN008D variant to match your personal style. This is a mechanical watch built to perform, not just to tell time.
