{"product_id":"steeldive-sd1928m-dive-watch","title":"STEELDIVE SD1928M — 39MM Japan NH35 Automatic Dive Watch","description":"\u003cp\u003eThe \u003cstrong\u003eSTEELDIVE SD1928M\u003c\/strong\u003e 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 39 mm 316L Stainless Steel case and 20 ATM 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 3 colourway \/ strap options — each piece ships in the original STEELDIVE presentation box with diver's extension tool and warranty card.
