Seiko Prospex

Limited Edition 1965 Heritage Save the Ocean “Tranquil Teal” Diver’s Watch

The Seiko Prospex SPB545J1 continues a proud legacy that began in 1965, when Seiko created Japan’s first diver’s watch and set a new global benchmark for underwater timekeeping. This Prospex Diver’s 300m model not only honours that pioneering heritage but also reflects Seiko’s ongoing commitment to marine conservation through the Save the Ocean initiative, supporting the protection of oceans for future generations of divers.

Its vivid ‘tranquil teal’ blue dial captures the essence of the sea, while LumiBrite-coated hands and indices ensure outstanding legibility even in the darkest depths. Housed in a durable 40mm case with a super-hard coating, the watch features a unidirectional rotating bezel designed for safe and reliable use during professional diving activities.

Powering the SPB545J1 is the in-house 6R55 automatic calibre, offering a substantial 72-hour power reserve and accuracy of -15/+25 seconds per day. With water resistance up to 300 metres, this Prospex timepiece is engineered to meet the demanding standards of professional diving environments, delivering the practicality, reliability and durability that define the Prospex name.
