Seiko Launch Prospex Marinemaster 1965 Reinterpretation Diver with Sporty Aesthetic and Calibre 6L37

Seiko have a penchant for revival designs that reimagine how heritage designs would look in their modern collections. Their latest release, the Seiko Prospex Marinemaster 1965 Reinterpretation Diver, is a fusion of two such heritage designs, the original Seiko diver from 1965 and the Marinemaster from the 2000s. This unique combination introduces a sporty new dial to the Prospex range.

The case is based on the 1965 diver’s reinterpretation that we’ve seen a few times recently. It has a 39.5mm diameter in stainless steel with 200m water resistance. The shape is quite striking with particularly long lugs (the watch has a length of 47.2mm), facetted flanks and brushed finishing.

However, what makes the watch stand out from previous editions of the 1965 Diver is the dial, of which there are three versions. The Seiko Prospex ‘Clearwater’ Marinemaster 1965 Reinterpretation Diver has an icy blue dial with a dark blue diving bezel, the ‘Dark Water’ reference has a black dial with matching black bezel and lastly the ‘High Water’ Seiko 100^th Anniversary limited edition with a white dial and steel tone bezel.

Each of the dials features a horizontal line pattern that gives each piece a strong sports aesthetic akin to the most famous luxury sports watch ever produced, the Patek Philippe Nautilus. At the same time, they feature a set of hour markers and hands that are much squarer than any other Prospex, something best shown through a single rectangle at 12 o’clock where they typically use a triangle, shield shape or double rectangle. It really helps to sell the sporty vibe, bolder and tougher than previous iterations.

Beneath the surface is the new 6L37 slimline automatic movement, first introduced in the Ref. SJE093 launched earlier this year. It has a 45-hour power reserve and an accuracy of -10/+15 seconds per day.  What makes it special is the fact it has a thickness of just 3.69mm, allowing the watch itself to have a thickness of just 12.3mm – the slimmest the 1965 case has ever been. On top of that, this is Seiko’s first 1965 Diver with an exhibition caseback, allowing you to see the movement inside.

All three versions of the Seiko Prospex Marinemaster 1965 Reinterpretation Diver are priced at £2,990. The ‘Clearwater’ and ‘Dark Water’ are being added to the main collection while the ‘High Water’ is limited to 1,000 pieces. That’s a pretty extreme price for a Seiko, the justification for which is that this is the first time the Calibre 6L37 has been available in their regular collections and it also sports a completely fresh dial. They set out to make a sporty Prospex diver and they’ve certainly achieved that goal, even if it’s at a bit more of a serious price.
