The Seiko Prospex SPB501J1 stands as a masterful blend of historic inspiration and modern dive-watch engineering. Drawing its design cues from Seiko’s first diver’s watch from 1965, the case measures 40.0 mm in diameter, 13.0 mm in thickness and 46.4 mm lug-to-lug. The stainless steel case houses a curved sapphire crystal with inner anti-reflective coating and a unidirectional rotating bezel, giving it both refined appearance and robust functionality.
Its signature emerald green gradient dial evokes the shifting light beneath the ocean’s surface while the appliqued lume-filled markers and hands deliver superb legibility. The movement within is Seiko’s in-house Calibre 6R55, offering approximately 72 hours of power reserve, automatic winding plus manual wind capability, and a stated accuracy of +25 to −15 seconds per day. Water resistance is rated to 300 metres and magnetic resistance is 4,800 A/m, making this timepiece worthy of serious underwater use or everyday adventure. The bracelet features a three-fold clasp with secure lock and push button release plus a slide adjuster for fit comfort. Limited edition details including a special case-back engravement honour the partnership with the Professional Association of Diving Instructors (PADI).
Featuring heritage styling, modern materials and purpose-built performance, the SPB501J1 captures Seiko’s diver-watch pedigree while catering to collectors who value both history and innovation in one compelling package.
