STEELDIVE SD1958S — 41.1MM Solid Bronze Case 200M Sapphire Glass NH35 Dive Watch

The STEELDIVE SD1958S is a vintage skin-diver in the classic 1960s cushion-case tradition, built around the Seiko NH35 Automatic movement and engineered with proper dive-watch tolerances. Defining features include cushion-case proportions, fat applied indices and a clear vintage-diver presence, giving it instant on-wrist character that reads more expensive than the price suggests. Build details include the 41.1 mm Solid Bronze (CuSn8) case, a Sapphire (AR-coated) crystal for everyday scratch resistance, and 200m of water resistance with a screw-down crown. The Japanese movement inside is the same workhorse calibre used across the modder community for over a decade — 24 jewels, hacking seconds, manual winding and a real-world ~41-hour power reserve that keeps it running through a full weekend off-wrist. It will appeal to wearers who want their watch to age with them — collectors who enjoy developing a personal patina, divers who appreciate non-traditional case materials, and buyers building a non-stainless rotation. Available in 3 colourway / strap options — each piece ships in the original STEELDIVE presentation box with diver's extension tool and warranty card.
