Product Details
The STEELDIVE SD1975K is SteelDive's 47.5mm shrouded tuna diver in black, fitted to a heavy stainless steel tank bracelet. The black Marineengineer dial carries large round lume plots, a date window and a black ceramic 120-click unidirectional bezel, all protected by a screwed steel shroud. It is rated to 300M — printed on the dial and engraved on the caseback — under a sapphire crystal with anti-reflective coating. The Seiko NH35 inside is the dependable Japanese workhorse calibre: 24 jewels, 21,600 vph, hacking seconds, hand-winding and roughly a 41-hour power reserve. Each watch ships in the STEELDIVE box with an extra strap and a warranty card.
