Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition in ‘tranquil teal’ Teal Dial Men 40mm SPB545J1

Seiko Prospex SPB545J1 — 'Save the Ocean' 1965 Heritage Diver in Tranquil Teal

The Seiko Prospex SPB545J1 traces its design directly back to 1965, when Seiko created Japan's first diver's watch and set a new global benchmark for underwater instruments. This reference carries that legacy forward as part of Seiko's ongoing Save the Ocean series — a line that pairs vintage-inspired diver design with support for marine conservation efforts, making it a watch with a story beyond specs.

The standout feature is the 'tranquil teal' dial — a vivid sea-toned blue-green finish with LumiBrite on the hands and indices for clear low-light legibility, a detail that matters for a genuine tool watch rather than just a design accent. At 40mm, it sits smaller and more wearable day-to-day than many modern dive watches, with a super-hard coated case and unidirectional rotating bezel built for real diving use.

Inside is Seiko's in-house Calibre 6R55 automatic movement, delivering a 72-hour power reserve and accuracy of -15/+25 seconds per day. Rated to 300m water resistance, this is a genuine professional dive tool, not a diver-styled dress watch — while the compact 40mm case keeps it comfortable for everyday wear too.

As part of a limited Save the Ocean edition, availability is finite — once Zimson's allocation is sold, restock isn't guaranteed.

At Zimson, the SPB545J1 comes with full Seiko manufacturer warranty, authentic packaging, and an invoice — as an authorized Seiko retailer in India since 1948.
