Ultra Thin Edition Cases

Case

Compact watches, properly engineered. The Ultra Thin Edition is our in-house case architecture — built around a 28.5mm chapter ring, 7.59mm NH caliber, and a total height of 9.96mm. The result: small wrists get a proper modern silhouette, not a chunky NH-stock compromise.

Every case in this line shares the same DNA — slim profile, 20mm lug width, and tight tolerances against our dials, hands, and bezels. Mix and match across the lineup with confidence: a Bauhaus 33 dial drops cleanly into a Pilot 34. An Explorer hand set fits the 1908. The architecture is the constant.

The lineup

Bauhaus 33mm — minimalist, dress-leaning, the smallest of the family.
Pilot 34mm — flieger-inspired, diamond-style crown options, cockpit-ready.
Explorer 36mm — the workhorse. Stainless, DLC black, polished titanium, sandblasted titanium.
1908 36mm — dressy lugs, available in stainless and yellow gold.
62GS 36mm — bezel-less Zaratsu-finished facets, crown at 4 o'clock, full Grand Seiko homage architecture.
Seiko-Dweller 36mm — titanium, sport-utility silhouette, our most rugged compact.
Seikonaut 38mm — flieger-meets-sport, available in stainless and titanium.
SKX013 Diver 38mm — the diver of the family, faithful to the SKX013 silhouette in black or green.

Materials: 316L stainless steel or Grade 4 titanium. Movements: NH35, NH36, and NH34 (GMT) compatible across the line — check individual product pages for caliber compatibility. Crown styles (coin edge, knurled, onion, diamond, 1908) are customer-selected at checkout via Infinite Options.

This is the case architecture we wish existed when we started modding in 2018. So we built it.
