Seiko Prospex Sea Stainless Steel Strap Men Watch SPB509J1
Celebrate six decades of dive watch innovation with the Seiko Prospex SPB509J1 Diver’s 60th Anniversary Limited Edition. This exclusive timepiece pays tribute to Seiko’s pioneering 1965 and 1968 diver models, blending heritage design with modern engineering.
The striking wave-pattern dial draws inspiration from The Great Wave off Kanagawa by Hokusai — a symbol of power and resilience. Its 40mm stainless steel case with super-hard coating houses a 6R54 automatic GMT movement, offering ±15/25 seconds per day accuracy and a 3-day power reserve.
Equipped for serious diving, the SPB509J1 features a ceramic unidirectional bezel, 300m water resistance, and screw-down crown for enhanced durability. For the first time in a Prospex model, the short-pitch stainless steel bracelet includes a micro-adjustable clasp for all-day comfort and secure fit.
