Seiko Prospex HBC005J1 1965 Heritage Diver 145th Anniversary Limited Edition

The Seiko Prospex HBC005J1 is a highly collectible, technically advanced tribute to Japan’s pioneering 1965 dive watch—the legendary 62MAS—released in celebration of Seiko’s 145th anniversary. Limited to just 4,000 pieces worldwide, this premium mechanical tool watch pairs an elegant, lightly brushed silver-white dial with a striking aluminum bezel insert and seconds hand finished in signature "Seiko Blue." Built for demanding real-world performance, the compact and highly wearable 40mm stainless steel case features a super-hard scratch-resistant coating, an inner-AR coated curved sapphire crystal, a secure screw-down crown, and an upgraded professional-tier 300-meter (1,000 feet) water resistance rating. Powering the timepiece is the high-performance, in-house Seiko Caliber 6R55 automatic movement, which boasts a substantial 72-hour (3-day) power reserve, while the matching solid-link steel bracelet introduces a revolutionary, new-generation folding clasp featuring a tool-free 15mm micro-adjustment slide mechanism for effortless, everyday comfort.
