About this entry
67% of key specs known. Missing: weight, hardening, AR coating, crown, bracelet offered.
The no-date build of Signum's original 42.5mm steel Cuda diver (Seiko NH38), sold through the same four store listings as Cuda Steel 42.5mm (NH35) by choosing "no date", at the same price. Brand specs: 316L steel, 42.5mm (44mm including the crown guards), 48mm lug-to-lug, 13.6mm, 22mm bracelet width, ceramic bezel, sapphire crystal, Super-LumiNova hands and markers, 200m; the full-lume dials are coated in several layers of Super-LumiNova with BGW9 on the hands and indices. Worn & Wound (2020 launch) adds the unidirectional bezel and polished applied indices and gives the same 13.6mm. Whether the thickness includes the crystal isn't stated. Crown type, caseback, bracelet construction and weight aren't stated; photos show it on a steel bracelet. USD 399 for every dial on 2026-10-24. Stone and shell dials are each unique.
