SKX013 Submariner Watch Case - 36mm [NH34-Ready]

Two SKX013-spec casebacks, both sold separately: a solid caseback for a clean closed back, or a sapphire (exhibition) caseback that reveals a decorated movement, bridge and rotor. Either keeps this sub-style skin-diver rated to 200m / 20 ATM. Pick solid for a vintage tool look; pick sapphire if you're running a decorated bridge and rotor on display.

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.

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.

No — only Lucius Atelier bracelets fit.

A bracelet isn't like a strap. Straps and NATOs hang off plain spring bars, so any 20mm strap works here. A bracelet with solid end-links is a different thing: the end-link is a shaped piece of steel machined to sit flush against one specific case profile. Ours are cut to the Lucius Atelier case shapes — that's what makes them look built-in rather than bolted on.

That precision cuts both ways. An aftermarket or OEM Seiko bracelet was shaped to its own maker's case, not to ours, so it won't sit flush here. The reverse is equally true: our bracelets don't fit generic 20mm lugs or OEM Seiko cases.

Every bracelet in our collection fits this case — including discontinued ones. A bracelet leaving the catalogue only means we stopped making it, never that it stopped fitting. Browse the bracelet collection: https://luciusatelier.com/collections/bracelets

If you'd rather not use a bracelet, any 20mm strap or NATO fits this case.
