SPB511J1
Honoring six decades of dive watch excellence, the Seiko Prospex SPB511J1 Diver’s 60th Anniversary Limited Edition pays tribute to the legendary 1965 '62MAS' — Seiko’s first diver’s watch. Its enduring legacy includes use by the Japanese Antarctic Research Expedition and explorers of Earth’s most extreme terrains. This modern interpretation features a silver wave-pattern dial inspired by Hokusai’s “The Great Wave,” encased in super-hard coated stainless steel with 300m water resistance. Powered by the in-house 6R55 automatic movement with 72-hour power reserve and a micro-adjustable clasp, this timepiece balances historical significance with modern functionality in a 40mm case.
