The SKX Diver at 38mm — Seiko NH and Swiss Movements in One Case.
The Diver Watch Case 38mm is our SKX013-spec dive case, engineered to take two very different movements: the full range of Seiko NH calibers, and high-end Swiss movements — the ETA2893 and Sellita SW330. One case body, two build routes.
It keeps the submariner-style crown guard and SKX silhouette modders know, and it fits every one of our SKX013 mod parts — dials, hands, chapter rings and crowns. The screw-down crown and caseback are unique to this case and come included.
Supplied as a donor case body and rated to 200m, so you choose the bezel, insert, crystal and chapter ring that suit your build.
Two movement families, one case body.
Run a Seiko NH build, or step up to the Swiss ETA2893 or Sellita SW330 — the matching gold movement spacer and caseback come with that selection. Few aftermarket cases take both.
SKX silhouette, submariner crown guard.
Diameter 38mm, lug-to-lug 44.5mm, 20mm lugs. The submariner-style crown guard keeps the SKX character while protecting the screw-down crown.
Fits every SKX013 mod part we make.
Our SKX013 dials (28.5mm), hands, chapter rings and crowns all drop in as expected. Tested on our own parts.
Seiko NH or Swiss ETA2893 / SW330.
NH35, NH36, NH37, NH38, NH39, NH70 and NH71 fit directly. For a Swiss build, the ETA2893 or Sellita SW330 seats on a dedicated gold movement spacer with its own caseback.
Built to dive.
200m / 20 ATM. Screw-down crown and screw-down caseback — both included, both unique to this case.
Heads up — sold separately
Bezel, insert & crystal. Selected from the options on this page — pick your rotating (or fixed) bezel, the insert, and your sapphire crystal to suit the build.
Chapter ring. A SKX013-spec chapter ring seats the dial at the correct height. Browse compatible chapter rings .
Dial, hands & movement. The face, hands and engine are chosen separately. Match the dial and hands to your movement (date / day-date / no-date).
Your screw-down crown and caseback are already included — they’re unique to this case and aren’t sold elsewhere.
Casebacks are NOT interchangeable between NH and ETA2893 / SW330
Each caseback is threaded to a different height to match its movement. Fitting an ETA2893 / SW330 caseback onto a case running an NH movement will damage the NH movement. Always match the caseback to your movement.
The ETA2893 and SW330 are expert-level builds. They run a fourth hand and leave roughly 40% less clearance between the hands than an NH caliber, so hand-setting is far less forgiving. Unless you’re a seasoned modder or a certified watchmaker, we’d steer you to the NH route.

What's already in this purchase:
The case body, your chosen caseback, the screw-down crown (unique to this case), bezel click spring, caseback gasket, crystal gasket and two fat spring bars. For an ETA2893 / SW330 build, a gold movement spacer is included with that selection.
The 5 parts you'll need for a complete watch:
- Bezel, insert & crystal Selected from the options above on this page — a rotating or fixed bezel, the matching insert, and your sapphire crystal.
-
Chapter ring SKX013-spec — seats the dial at the correct height.
Browse compatible chapter rings - Dial (28.5mm) The face of the watch. Match it to your movement (date / day-date / no-date).

Optional finishing touches:
- Decorated bridge + rotor (only visible with a sapphire caseback) — replace the stock NH bridge and rotor with our Côtes de Genève decorated set, viewable through the caseback.

Questions, Answered
Everything worth knowing before you build.
Which caseback should I choose for the Diver Watch Case 38mm?
Which movements fit the Diver Watch Case 38mm?
Are the case and bracelet edges sharp, or are they rounded off?
Do you customize cases? Can I have a case machined or finished to my own spec?
This 38mm diver watch case is highly praised for its "quality finish" and compatibility with SKX013 parts. Customers describe it as "perfect for small wrists" with excellent build quality. Some note the crown is difficult to access within guards and hard to screw/unscrew. Ideal for watch modding with NH & GMT movements, supporting various customization options.
- The quality of this case is very very high. I was amazed by it.
- Quality finish, fantastic look and feel. Beyond my expectations.
- Absolutely love this case. The finishing is perfect.

Using this mod part for: SKX013 39mm is the key
Not a simple build and my friend is a watch maker, so I hope this helps.
I had intended to use a White Birch dial, but the texture and it's thickness won't allow a GMT hand to work. Switching to another dial and we find that the sweep of the GMT hand needs to be inside the Indices, if the hands are all tilted up to clear, the second hand hits the crystal. Final hurdle is that with the ETA 2893 movement, the case back won't go home, so needs some taking off the chapter ring or the supplied silver movement ring.
But...what a result.
38mm GMT with a Suisse chronometer grade movement in a Mods.
Awesome.
Thank you Adriel.

Using this mod part for: Batman-inspired 38mm submariner SKX013
Very happy to find a 38mm version of the explorer case! Finish on the case is truly great! If I may suggest a couple of things to improve, if possible, it would be the crown, which is very hard to screw and unscrew due to the crown guards (it may be the same with the original Rolex, but I wouldn’t know). Also, my original Skx013 end links don’t fit well. Again, it sure if they both got bent, but the jury is still out about that.

Beautifully made and perfect size for me. Perfect that it can be customized with the SKX013 parts.
I also like the handwritten notes.

The best midsize case

Using this mod part for: SKX013
This case has great proportions and the finishing is awesome. It fits well with aftermarket SKX013 parts from Namoki, Watch&Style, and Uncle Seiko. The only reason I'm giving it 4 stars instead of 5 is the crown is rather small and difficult to get to in the crown guards. Made the crown can be enlarged on later versions? Otherwise very well done. I love the hand written notes!

I’ve been waiting for a sub styled 38mm case for years and they have just gone and done it. The finish looks great and the best thing about it, it’s compatible with all seiko skx013 parts.
Shipping arrived super fast within a few days
