STEELDIVE SD1987 — Tank Bracelet 2000M Japan NH35 Automatic Dive Watch

The STEELDIVE SD1987 is a big-size 46.5mm professional-grade tool diver with monocoque-style heft, built around the Seiko NH35 Automatic movement and engineered with proper dive-watch tolerances. Defining features include oversized broad-arrow hands, broad lume plots and serious wrist presence, giving it instant on-wrist character that reads more expensive than the price suggests. Build details include the 316L Stainless Steel case and 2000m 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 suits divers, tool-watch collectors and everyday wearers looking for serious build quality, Japanese-movement reliability and proper dive-watch construction at a fraction of Swiss pricing. Available in 2 colourway / strap options — each piece ships in the original STEELDIVE presentation box with diver's extension tool and warranty card.
