STEELDIVE SD1940 — 39mm Pilot Watch 200m NH35 Automatic Dive Watch
STEELDIVE SD1940 — 39mm Pilot Watch 200m NH35 Automatic Dive Watch
Product Details
The STEELDIVE SD1940 is a compact 39mm pilot-styled tool watch with diver-grade build quality, built around the Seiko NH35 Automatic movement and engineered with proper dive-watch tolerances. Defining features include a clean Flieger-style dial, syringe hands and pilot-watch proportions, giving it instant on-wrist character that reads more expensive than the price suggests. Build details include the 39 mm 316L Stainless Steel case 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 suits everyday wearers chasing a clean Flieger-style dial — aviation-watch fans on a budget, smaller-wrist owners frustrated with oversized pilots, and travellers wanting a no-nonsense daily. Available in 6 colourway / strap options — each piece ships in the original STEELDIVE presentation box with diver's extension tool and warranty card.
