Seiko Prospex 1968 Heritage Diver GMT – Exclusive to Europe

Seiko Prospex 1968 Heritage Diver GMT “Seashadow” with reference number SPB534  is a new model launched by Seiko exclusive to Europe, limited to 500 pieces and inspired by Seiko’s historic 1968 professional divers. 

It’s clear for all of us that Seiko is taking a new approach when it comes to their watches trying to revive old models and giving them a refresh, like they did with King Seiko VANAC.

Seiko Prospex 1968 Heritage Diver GMT  Case and Design

I know there are some people that consider 42 mm a big watch, I’m not one of those people, so for me it kinda is the perfect dimension. You guessed it , this model is measuring 42 mm in diameter, 48.6 mm lug-to-lug, and 13.3 mm thick. I’m gonna give it to this Seiko, it has presence and wearability.

The case is made from stainless steel and it has a coating for protection against scratches, also the bezel, which is unidirectional, is fitted with a scratch resistant ceramic insert. Screw-down crown is also present and together with the case back ensures a 300m water-resistance rating. If you need more information about Dive Watches, we have a comprehensive guide that explains everything.

Dial and Visual 

Inspired by the legendary 6215 and 6159 models, the high-gloss black dial has gold-toned accents applied on indices, hands and text. And I guess this gives Seiko Prospex 1968 Heritage Diver GMT a balance between sportiness and elegance. 

White is present there as a non-colour of course, but it gives a perfect balance and also improved legibility alongside with the gray GMT hand. LumiBrite, which is a proprietary lume, provides reliable night-time visibility. 

On the case back we can find the limited edition number engraved. 

Movement and Features

The heart of the watch is Seiko’s in-house caliber 6R54 which delivers a three days (72 hours) power reserve.  The frequency is 21.600 vph  which I think is low, but that’s just me, and it has an accuracy rating of +25/-15 seconds per day. 

The movement 6R54 supports hacking, manual winding, a quick-set date and an independently adjustable 24 hour GMT hand. 

This model also features a magnetic resistance of 4800 A/m. 

Not great, not terrible i would say.

Bracelet and Comfort

Well, I didn’t wear the watch, so I don’t know how comfortable it is, but I can tell you that a new feature is making its debut for the Prospex line: a three row stainless steel bracelet with a quick setting micro adjustable clasp extension. 

Cool? Ok! The bracelet supports a 20 mm lug width and provides a solid and professional presence. 

Worth mentioning that the total weight is 188 grams. Which is good, not that heavy as my Omega Seamaster 300M.

Exclusivity and Pricing for Seiko Prospex 1968 Heritage Diver GMT

Here comes the fun part. Yes the watch is exclusive to Europe and it is limited to 500 pieces? What does that mean? Nothing! Except the fact that there are 500 pieces and you can buy it only in Europe. It will not grow in value, you will not make a huge profit from this watch. 

The watch can be purchased through Seiko boutiques and the price is 1600 british pounds. Expensive? 

Each watch features “LIMITED EDITION” and an unique serial number engraved on the caseback. 

I don’t love it and I don’t hate it. Would I ever pay 1600 pounds for it? Well, no, not because it’s not good, but it’s not my cup of tea.
