SPB501J1
The Seiko Prospex SPB501J1 1965 Heritage Diver’s PADI Special Edition Men Watch pays tribute to Seiko’s first-ever diver’s watch, the 1965 ‘62MAS,’ worn by Japanese Antarctic Research Expedition teams and global adventurers. Designed in collaboration with PADI, it features a deep green dial inspired by the ocean’s surface with sunburst detailing, set in a 40mm stainless steel case with super-hard coating. Powered by the in-house 6R55 automatic calibre, it offers a 72-hour power reserve, date display at 4.5 o’clock, and 300m water resistance. Delivered with a stainless steel bracelet and an additional eco-friendly green strap crafted from recycled fishing nets, this professional-grade diver’s watch combines heritage, sustainability, and reliability.
