Product Details

The STEELDIVE SD1912 is an ultra-deep saturation-class diver built for serious depth ratings, built around the Seiko NH35 Automatic movement and engineered with proper dive-watch tolerances. Defining features include a thick monobloc steel case, helium escape valve detailing and a 3000m-rated build, giving it instant on-wrist character that reads more expensive than the price suggests. Build details include the 47 mm 316L Stainless Steel case and 3000m 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 is built for serious tool-watch wearers — saturation-diver homage collectors, fans of thick-case wristwear and anyone who treats their watch as functional kit rather than jewellery. Available in 4 colourway / strap options — each piece ships in the original STEELDIVE presentation box with diver's extension tool and warranty card.
