Steel Hammerhead Field (released April/May 2026), a fixed-bezel, no-date (Seiko NH38) version of the Hammerhead diver; 13mm thick with crystal and 300m WR. The CuSn8 bronze versions (Bedrock, Vesper, Mosaic MOP, on FKM rubber, also $499) are a separate model. The DLC Storm variant has a black DLC coating on case and bracelet that Zelos says is "hardened to withstand scratches"; the other steel variants have no hardening mentioned, so case.hardening is left blank at model level. Fixed steel bezel per SeriousWatches. Lume: Super-LumiNova C3/BGW9 with Lumicast 3/6/9 indices. Clasp: "Quick adjust clasp with external release"; recorded as on-the-fly because Zelos describes its external-button quick adjust clasp (Swordfish page) as adjustable "without having to undo the clasp"; positions/range not stated for this model. Solid end links per SeriousWatches. Bracelet link count, link attachment and weight not found. Only DLC Storm was in stock on 2026-10-20.
