Seiko Monster-style diver ("Design: Monster"). Brand specs from the 2025 listing: 316L case, 41.6mm without crown, 46.56mm lug-to-lug, 13.6mm high, 28.9mm dial, 20mm lugs (drilled), flat sapphire (AR not mentioned), unidirectional bezel with a steel insert, Hangzhou 2553A automatic (day-date), "Japan SuperLuminova C3" green lume, rocket hands, unsigned screw-down crown, 200m, 192.8g (presumably on the bracelet; not stated), "stainless steel dive strap" (bracelet) with a solid milled clasp. Black dial with red hands in both versions; the listing also mentions blue, red, olive green and orange dials that are not offered as options. The PVD black version is a black-coated case on a nylon band. Caseback, bracelet style and micro-adjust are not stated. Both versions $139 (crossed-out $368). Those dial colours are sold through an older listing (heimdallr-monster-automatic-dive-watch) with the same spec block: red, orange, blue, olive and black dials with the steel bezel, plus black bezel/frosted blue dial, blue bezel/gradient blue dial and blue bezel/blue dial, all on the steel bracelet at $139 (crossed-out $368); its SKUs mark them as V1 and V2 dials. Orange and olive were sold out on 2026-10-21. Two more listings carry the same spec block (316L, 41.6mm, 46.56mm lug-to-lug, 13.6mm, 20mm lugs, flat sapphire, steel insert, Hangzhou 2553A, C3, 200m, 192.8g): the PVD listing (heimdallr-pvd-black-sharkey-ocean-monster-dive-watch; "316L Stainless Steel, PVD coating", nylon fabric strap) sells the black PVD case and bezel with gradient brown, full-lume, red, blue, orange, olive and black dials (the black one with silver hands, unlike the red-handed PVD version of the 2025 listing), all $139 (crossed-out $279); the V2 listing (v2-heimdallr-sharkey-ocean-monster-dive-watch-in-stock; "Version: V2", steel bracelet with solid milled clasp) sells frost blue and snow white (frosted-pattern), red, yellow and orange dials with baton indices, each with black- or silver-edged hands, all $139 (crossed-out $368). All seventeen were in stock on 2026-10-21. No independent review found.
