The Smallest Sub-Style Diver. 36mm. Ready to Mod.

A ground-up take on the definitive 1960s skin-diver silhouette — drilled-through lugs and gently pointed crown guards, in a rare, compact 36mm.

One of the smallest sub-style dive cases on the market. Add a bezel insert and it wears far bigger than the numbers suggest. NH34 GMT-ready and built to fit our full SKX013 parts range.

Designed for all our 28.5mm dials and original NH movements (grey dial holding spacer). Pairs especially well with a 7mm big crown.

This edition wears a DLC black coating — diamond-like carbon, roughly five times the surface hardness of 316L steel and far more scratch-resistant than standard PVD. A deep, durable black built for daily wear.

Small case, big wrist presence.
Case diameter 36mm, lug-to-lug 45.5mm, 20mm lugs. With an insert fitted it punches well above its size.

Vintage dive DNA.
Drilled-through lugs and slightly pointed crown guards — faithful to the era's tool divers.

Built to dive.
200m / 20 ATM, tested. Screw-down crown — we recommend a 7mm big crown for grip.

Fits the whole SKX013 ecosystem.
Bezel, insert, sapphire crystal, chapter ring, crown, dial, hands — all from our SKX013 range. 28.5mm dials; NH movements on the grey dial holding spacer.

The SKX013 case family — find your size

Case	Diameter	Lug-to-Lug	Character
SKX013 38mm	38mm	45.5mm	Our take on the discontinued SKX013 diver
SKX013 Submariner 36mm · YOU'RE VIEWING THIS	36mm	45.5mm	Vintage sub-style skin-diver
SKX013 GS Diver 36mm	36mm	44mm	GS-style diver, most compact

All three share the same DNA — 316L steel or DLC black, 200m / 20 ATM, drilled-through lugs, 28.5mm dials, NH movements, and a 20mm bracelet or strap. What differs is size and silhouette.

This exact case also comes in the natural 316L steel version .

Heads up — this is the case body. The rest is sold separately.

This case ships as a bare body (with click spring and gaskets). The bezel, insert, crystal, caseback, chapter ring, crown, dial, hands and movement are chosen separately — it's built to fit our full SKX013 parts range .

Chapter ring. This case needs an SKX013-spec chapter ring to seat the dial correctly — without it the dial sits too low and the hands won't clear. It takes both normal and ultra thin chapter rings; the choice depends on your dial, not the case. If your dial has applied (raised) indices, pick an ultra thin chapter ring for clearance; a flat-printed dial works with either. Browse SKX013 chapter rings .

Crown. Screw-down, SKX-style — we recommend a 7mm big crown on this case for grip. Browse SKX013 crowns .

New to Seiko modding? You can build the whole watch right here — every part is an Add dropdown on this page. The case ships as a bare body (with the bezel click spring and the crystal & caseback gaskets); you choose the rest and spec it exactly how you like.

Ten parts make a complete watch. You've got the case — here are the other nine, each a dropdown above, in the order you'd assemble them:
1. Bezel — the rotating dive bezel. Browse SKX013 bezels .
2. Bezel insert — the marked ring that sits inside the bezel. Browse inserts .
3. Caseback — seals the case; solid, or sapphire to show off a decorated movement. Browse SKX013 parts .
4. Chapter ring (required — seats the dial) — SKX013-spec; without it the dial sits too low and the hands won't clear. Browse chapter rings .
5. Crown (required) — screw-down, SKX-style. We suggest a 7mm big crown on this case for a better grip. Browse SKX013 crowns .
6. Crystal — flat sapphire, pressed into the case. Browse SKX013 crystals .
7. Dial (28.5mm) — match it to your movement: date, day+date, or no-date. Browse dials .
8. Hands — paired to your dial; most modders match lume colour across hands and markers. Browse hands .
9. Movement — NH35 (date), NH36 (day+date), NH38 (no date), or fit your own. Browse NH movements .
Building an NH34 GMT? Add a GMT 24H hand (its own dropdown) and a GMT / NH34-specific dial — the 24-hour hand is the one optional extra on top of the ten.

Optional extras (also dropdowns above): a 20mm bracelet or leather strap , and a Côtes de Genève decorated bridge + rotor — only visible through a sapphire caseback, and our bridges pair only with our rotors, so pick them together.

Want it built for you?

Under ADD, tick Assemble Watch (+SGD $100) and we'll do the full build in our Singapore workshop — crystal press, bezel and insert fit, movement seating, crown alignment, caseback press, and a final function check.

Heads up: assembled watches need 2–5 business days of workshop time before they ship.

Prefer to build it yourself? See the How To Mod tab for step-by-step tutorials.
1. 1x Watch Case Body

Which caseback should I choose for the SKX013 Submariner Watch Case 36mm DLC Black Edition?

Two SKX013-spec casebacks, both sold separately: a solid caseback for a clean closed back, or a sapphire (exhibition) caseback to reveal a decorated movement, bridge and rotor. Either keeps this DLC sub-style skin-diver rated to 200m / 20 ATM. Choose solid for a stealth closed back; choose sapphire if you've added a decorated bridge and rotor worth seeing.

Are the case and bracelet edges sharp, or are they rounded off?

They are rounded off — but they are still crisp, and we would rather say that than have you open the box expecting something softer. "Sharp" is genuinely subjective: a Rolex is sharp too, and where one person reads that as crisp and well-defined, another finds it catches. The bracelet clasp is the sharpest part of the whole package — that is the part to know about before you commit.

If a previous mod was painful to wear, it is worth working out what actually caused it: a poorly finished lug edge digging in is a different problem from a clasp catching on the back of your wrist. Email hello@luciusatelier.com and say which it was, and you will get an honest answer on whether ours will be better or much the same.

Do you customize cases? Can I have a case machined or finished to my own spec?

Cases ship exactly as listed — no custom machining, no changes to size, lug width or lug shape, no alternative finishes of an existing case, and no engraving (a local engraver or jeweller can engrave a finished part after purchase). What you can customize is the build: choose the case, dial, hands, chapter ring, bezel insert, crystal and bracelet you want and LA will assemble the finished watch for you. Bespoke design work — one-off dials, mockups or renders, designing a build to a brief — is not offered. For fully custom work, see the list of watch modification specialists.
