{"product_id":"steeldive-sd1912-sapphire-dive-watch","title":"STEELDIVE SD1912 — V2 Vintage 47MM Big Size Sapphire Glass NH35 Dive Watch","description":"\u003cp\u003eThe \u003cstrong\u003eSTEELDIVE SD1912\u003c\/strong\u003e 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 a Sapphire (AR-coated) crystal for everyday scratch resistance. 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 vintage-diver enthusiasts, military-watch collectors and modern buyers chasing the no-date military silhouette at a contemporary build quality. Available in 4 colourway \/ strap options — each piece ships in the original STEELDIVE presentation box with diver's extension tool and warranty card.
