SEIKO PROSPEX BLACK SERIES LIMITED EDITION SUMO AUTOMATIC DIVER'S WATCH – 45MM BLACK DIAL STEEL BRACELET
SPB125J1
Seiko's Prospex Black Series brought a dramatic all-over blackout treatment to some of its most celebrated diver shapes. The SPB125J1 applies that treatment to the Sumo — arguably Seiko's most respected diver case — coating every external surface in a hard black finish and pairing it with a black dial and bracelet for a total stealth effect. The 6R35 automatic calibre inside is one of Seiko's best, with a 70-hour power reserve and hand-winding capability.
Why This Watch Stands Out
- Hard black coating on every external surface — the definitive Sumo blackout
- Limited edition designation — a collector's piece from one of Seiko's strongest diver lines
- Seiko Calibre 6R35 automatic — 70-hour power reserve, hacking and hand-winding
- Sapphire crystal with anti-reflective coating on both sides
- 200-metre diver's water resistance — the full specification of the standard Sumo
