Seiko Adds a Mechanical GMT Function to Its Prospex Diver for the First Time Ever

With two decades separating the introduction of the first-ever diver and first-ever GMT in the ‘30s and ‘50s, respectively, the two watches have largely occupied separate spaces, albeit with some overlap. That overlap often comes in the way of a GMT with diving capabilities, but less so the other way around.

Since launching the Prospex range back in 1965, Seiko’s flagship diver has remained mechanical GMT-free until launching a new trio of watches today based on the 1968 Diver’s Modern Re-interpretation models. While retaining the design language of the standard Prospex diver, the new watches feature a fourth GMT hand that moves along the associated 24-hour inner flange so you can keep track of a second time zone.

Up until now, the only dive watches in Seiko’s lineup that ever came with mechanical GMT functionality were from the 5 Sports range. Although, a Spring Driver GMT did pop up in the luxury Prospex LX line a few years back in limited quantities. Available in green, black, and limited-to-4,000 Save the Ocean blue variants, this new Prospex GMT sports a brand-new movement as well: the automatic caliber 6R54, which boasts 72 hours of power reserve.

Dropping this June, the Seiko Prospex 1968 Diver’s Modern Re-interpretation GMT will be priced at $1,500 for both the black and green versions and $1,700 for the Save the Ocean version.
