Third-generation Hammerhead, a slimmer 300m redesign of the 1000m original, first listed by Zelos on 28 April 2021 in 316L steel on a steel bracelet; all eight colourways are now in its Discontinued Models collection. The bronze (2022) and titanium (2023) versions and the 2022 Damascus steel, crystallised titanium and tantalum limited editions are separate models. Zelos: 44mm, 48mm lug to lug, 22mm lugs, "13mm thickness without crystal", 300m. Total thickness with the double-domed sapphire is not stated, so it is not recorded; Zelos's 2026 Hammerhead page says the 43mm Field is 1mm thinner than the diver at 13mm with crystal, which suggests about 14mm for the diver. Seiko NH35 with a colour-matched date wheel; date at 6. Signed, lumed crown, screw-down and unidirectional bezel per SeriousWatches, which also lists a solid caseback. Bezel insert ceramic or steel per colourway (Zelos's colourway text; dive scale from the photos). Sunburst dials with C3 X1 and BGW9 lume per the spec list, though several colourways are fumé, mother-of-pearl, meteorite or fully lumed. Bracelet: 316L with a "quick adjust clasp"; the micro-adjust type is not described and the case steel grade is not stated (the bracelet is 316L). Weight not published.
