STEELDIVE SD1945S — 45.6MM Big Size Solid Bronze Case 3000M NH35 Dive Watch

The STEELDIVE SD1945S 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 45.6 mm Solid Bronze (CuSn8) 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 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 2 colourway / strap options — each piece ships in the original STEELDIVE presentation box with diver's extension tool and warranty card.
