Seiko SKX033 Technical specifications

I like to start off with a quick run through the general specifications of the watch. This gives you the opportunity to see if you like this style of watch from the get-go. For example, some people wouldn’t want to go for a very large watch.

  • Model Number: SKX033
  • Crystal Material: Hardlex crystal
  • Case Diameter: 39mm
  • Case Thickness: 12mm
  • Movement: 7S26 Automatic
  • Water Resistance: 100m / 10 bar

Seiko SKX033 Dial and Casing Design

The Seiko SKX033 “Submariner” as it’s known is a popular vintage Seiko diving watch. It features that typical diving style high visibility dial design with bold hands and hour markers that stand out well against the dark blue background of the dial. The hands and hour markers have a coating of lume for excellent visibility in dim lit conditions.

On the dial, we find the terms ‘Seiko’, ‘Automatic’, 21 jewels’ and the water resistance rating. There’s also a day and date feature at the 3 o’clock position on the dial.

The casing itself is made from stainless steel with a diameter of 39mm and a thickness of 12mm. A large uni-directional bezel sits on top of the watch with minute numbering and that classic Pepsi style blue and red colouring.

Note that the crown sits at the 3 o’clock position on this model and can be screwed down to help prevent it accidentally being pulled out.

Strap & Clasp

The strap on this Seiko SKX033 automatic diving watch can vary depending on where you find it. As it’s a vintage Seiko watch, you’ll likely be looking at second hand models online most of the time. You often find either a stainless steel, rubber, or Nato style strap attached to this watch.

Note that if you wish to do so, you can actually change the strap to whichever you prefer. The gap between the lug measures 22mm wide. Purchase a watch repair kit for all the tools required for this job.


The Seiko SKX033 Movement

At the heart of this popular vintage diving watch is the Seiko 7s26 caliber movement. This is a well-loved movement that features in many of Seiko’s most popular diving watches from the SKX collection.

The 7s26 is a 21 jewel movement that beats at 21,600 BPH, this gives you a nice and smooth 6 ticks per second sweeping second hand. When fully wound the movement has a power reserve of 43 hours, the movement doesn’t feature hacking.


Seiko SKX033 Crystal

At the front of the watch is a protective Hardlex crystal glass lens. This is a proprietary glass owned by Seiko and used in many of their watches. You’ll commonly find this is many Seiko, Pulsar, and Lorus watches. Hardlex glass gives you a good level of resistance to scratches and shattering, ideal for this type of timepiece.

A Final Word On The Seiko SKX033

The Seiko Diver SKX033 is a beautiful diving timepiece. It’s just a shame it’s so hard to get a hold of these days. If you trawl some of the bigger forums you may find a few people selling them at least.
