Second-generation Hammerhead, listed by Zelos on 25 November 2019 in CuSn8 bronze or 316L steel, each with a Seiko NH35 (solid caseback) or an ETA 2892 (sapphire display back and custom rotor); the four combinations are separate models and all 23 listings are in Zelos's Discontinued Models collection. Zelos lists the same specs for all: 44mm, 48mm lug to lug, 17mm high including the double-domed sapphire (15mm without), 22mm lugs, 1000m with a helium escape valve, alternating brushed and sandblasted finish, 120-click unidirectional bezel, C3-lumed screw-down crown, C3 and BGW9 lume with dual-lume hands, inner AR coating. Changes from the 2016 Hammerhead per Zelos: helium valve, dual-lume hands, improved build quality and a meteorite dive-bezel insert (treated against rust). Date at 6 (photos; SeriousWatches lists a date). Bezel insert (ceramic, bronze, steel or meteorite) per variant from Zelos's colourway text; dive scale from the photos. Screw-down crown and unidirectional bezel also per SeriousWatches. This file is the bronze case with the NH35 and its solid caseback. Sold on a custom rubber strap with a bronze buckle; no bracelet listed. Six colourways; the Patina is NH35 only. The product URLs say "launch special" but the pages don't say whether the prices were introductory. Weight not published.
