Seiko Prospex 140th Anniversary Automatic Scuba Divers SPB207J1 Green Dial

Celebrate Seiko’s legacy with the SPB207J1, a 140th Anniversary Limited Edition dive watch that pairs reliable professional performance with a bold, verdant look. The Island Green dial is inspired by Japan’s Iriomote Island forests, converting natural beauty into a high-precision instrument you can wear from reef dives to city streets.

Built for men who demand both rugged capability and distinctive style, this Prospex model blends a robust steel chassis with an elegant green dial, delivering legibility, durability, and heritage in a single timepiece. It’s not just about telling time underwater—it’s about wearing a piece of Seiko’s evolving dive-watch story.

Limited Edition significance

Only 5,000 pieces are available in this 140th Anniversary release. It’s part of a trilogy drawing inspiration from the dense verdant forests of Iriomote Island, a region famed for its pristine waters and diverse coral ecosystems. This modern upgrade of the 1968 Diver’s watch preserves Seiko’s pioneering spirit while delivering contemporary accuracy, reliability, and collectability for serious enthusiasts.

Design and visibility

The Island Green dial stands out with luminous hands and indexes, ensuring clear readability in low light and deep water. The sapphire crystal features an anti-reflective inner coating to minimize glare, while the black unidirectional rotating bezel provides precise timing control for dives. The 42mm stainless steel case with a hard coating offers a balanced silhouette that’s comfortable on the wrist yet tough enough to handle demanding environments.

Performance you can trust

Power comes from the automatic Caliber 6R35, complete with manual winding capability and a generous 70-hour power reserve. With 24 jewels and a precision range of +25 to -15 seconds per day, you’ll enjoy dependable timekeeping whether you’re underwater at depth or at the surface in changing conditions.

Durability and comfort

Designed for real-world use, the SPB207J1 features a screw-down crown and screw-case back for enhanced water resistance, rated up to 200 meters. The watch rides on a stainless steel strap and includes an extra silicone band for comfort and versatility. A three-fold clasp with secure lock and a push-button release with extender ensures a secure fit during active use. Weighing 186g, it strikes a solid, reassuring presence on the wrist without feeling bulky.
