The Seiko Prospex ‘Marinemaster’ JAMSTEC Limited Edition 1968 Heritage Reinterpretation is a distinguished evolution of an iconic diver’s watch, presented in a 42.6mm stainless steel case inspired by the original 1968 design. Developed in collaboration with JAMSTEC, the blue gradient dial reflects the trail of an icebreaking research vessel, enhanced with a satin finish to reduce reflection and improve underwater legibility. Protected by dual‑curved sapphire crystal and complemented by Lumibrite details and a unidirectional ceramic bezel, it meets ISO diving standards with water resistance to 300 metres. Powered by the in‑house 8L45 automatic calibre with a 72‑hour power reserve, and finished with a stainless steel bracelet featuring a sliding micro‑adjustable clasp, this limited edition model combines professional performance with distinctive design heritage.
