About this entry

74% of key specs known. Missing: thickness, weight, bracelet links, link attachment, clasp micro-adjust.

Grade 2 titanium version of the third-generation Hammerhead, sold by Zelos in two sold-out batches: 2 June 2023 (Chalk Blue, Electric Blue, Ember Orange, Hammered Red, Meteorite, Mosaic MOP, Ti-Damascus) and 25 September 2025 (Granite, Red Tiger's Eye, Teal Meteorite and the DLC Mosaic MOP). Zelos still lists all of them in its Hammerhead collection, not in Discontinued Models, but none has been restocked, so the model is recorded as limited (no edition size stated). The steel (2021) and bronze (2022) V3s and the 2022 crystallised titanium limited edition are separate models. Case and bracelet: "Ti Gr2 with 1200HV hardened coating"; the DLC Mosaic MOP (Zelos titles it "Hammerhead V3 300m DLC 'Mosiac MOP'") has the same Grade 2 titanium case with a black "DLC hardened coating" (hardness not stated) and a DLC-coated titanium bracelet that Zelos lists as "1200Hv hardened". Dimensions: 44mm, 22mm lugs, 300m; lug to lug is 48mm on the 2023 listings (and on all of SeriousWatches's listings) but 49mm on Zelos's 2025 listings, recorded as 48. Thickness is "13mm" on the 2023 listings and "13mm without crystal" on the 2025 listings and earlier V3s, so total thickness with crystal is not recorded (Zelos's 2026 Hammerhead page puts the diver 1mm thicker than the 13mm-with-crystal Field). Crystal: Zelos lists "domed sapphire with inner AR coating" here and "double domed" on the earlier V3s; SeriousWatches says double-domed. Seiko NH35 with a date at 6. Screw-down crown, unidirectional bezel, solid caseback and solid end links per SeriousWatches. Bezel insert per colourway from Zelos's colourway text: the 2023 spec list says "Ceramic with brushed finish" (Ember Orange has a lumed sapphire bezel), the 2025 spec list says "Sapphire" while SeriousWatches lists ceramic for the 2025 colourways; Ti-Damascus has a Ti-Damascus dial and bezel (Grade 5 and Grade 2 layers, heat treated at 400 °C). Clasp: "updated Quick adjust clasp" in 2023, "Quick adjust clasp with external release" in 2025; micro-adjust type not described, so not recorded. Lume C3 and BGW9; Ember Orange is fully lumed in orange Super-LumiNova and the DLC Mosaic MOP uses blue Super-LumiNova. Weight not published.
