SKX013 Diver 38 [Ultra Thin Edition]

The dive-watch silhouette that defined an era — reborn ultra thin.

The SKX013 Diver 38 is our ground-up reinterpretation of the dive-watch icon, engineered to be among the thinnest NH-compatible dive cases on the market today. 10.86mm with the Ultra Thin solid caseback. A 38mm case width that wears 40 with the crown guards. The dimensions of a daily driver, the lineage of a tool watch.

SKX013 thinness comparison — modded Seiko SKX013 at 14.5mm vs Lucius Atelier SKX013 Diver 38 Ultra Thin Edition at 10.86mm — *Same 38mm diameter. Stock SKX013 modded to 14.5mm vs. our SKX013 Diver 38 at 10.86mm — roughly 25% thinner.*

Achieving this profile meant rebuilding the case body from scratch. Every internal dimension was re-engineered to compress height without compromising structure — which is why the bezel and ceramic insert are dimensionally exclusive to this case, and why we ship them pre-fitted and pre-aligned at our Singapore workshop.

What we kept compatible: the things modders actually want flexibility on. SKX-style crowns. SKX013-spec chapter rings. 28.5mm Seiko Mod dials. Hands. NH35, NH36, NH38, NH70, NH71, NH72 (Type M).

Two colourways. Same case, same engineering.

Black ceramic insert — the original dive-watch language. Versatile, formal, timeless.
Green ceramic insert — the modern tool-watch flex. Bolder on the wrist, harder to ignore.

Both ship with three caseback options (Ultra Thin Solid, Thick Solid 200m, Sapphire) and two crystal options (cyclops or no-cyclops). Pick the build that matches how you'll actually wear it.

For experienced modders only — Type M NH movements only. Tight clearance between hands and sapphire.
