Zelos Spearfish Dual Time Carbon

About this entry

93% of key specs known. Missing: hardening.

Forged-carbon-cased version of the Spearfish Dual Time, listed on 2 April 2024 and on sale from 8 April 2024 alongside the titanium versions (Spearfish Dual Time Ti, a separate model: different case material, and sold on a bracelet). Two colourways, Supernova and Moonscape; both were sold out on 2026-10-21 and are still in Zelos's Spearfish collection, not in Discontinued Models, with no edition size stated, so the model is recorded as limited. Launch price US$1,849 (Worn & Wound, Fratello); the store now lists $2,199. Case: "Forged carbon" (Zelos; Worn & Wound: dark grey swirls on an almost black background), recorded with the schema's carbon value. 40mm, 47mm lug to lug, 20mm lugs, 100m with screw-down crown. Thickness: Zelos gives "10mm without crystal" with a "2.5mm thick" crystal; the 12.6mm total, including the box sapphire, is Worn & Wound's measurement of the Moonscape (Fratello gives 12.5mm for the titanium version). Weight per Worn & Wound: 41g for the head, 56g on the strap. Movement: "Swiss Sellita SW300 with TT651 Module. Grande Date, GMT and 24hr Subdial, Custom rotor"; the collection page calls the base an "elabore SW300 movement with blued screws and perlage" and the rotor "inspired by the Northstar"; Worn & Wound names the module maker, Technotime, and Fratello the base, SW300-1 with 56h power reserve. SeriousWatches's text says "SW300-2" and its spec table "SW330-2"; neither matches Zelos or Fratello, so they are not used. The movement is recorded as the SW300-1 with the module as a modification, and the displays as complications: a two-disc big date at 12 and a sub-dial at 6 whose own hour and minute hands show a second time zone (12-hour, set via the crown) over a lumed world disc that turns once a day as a day/night indicator. Worn & Wound found the big-date numerals never quite centred in their window, on its sample and others it saw online. Crystal: Zelos says "Vintage style domed Sapphire crystal with inner AR coating"; Worn & Wound calls it boxed and Fratello "box-type double-domed", so it is recorded as box-domed. Display caseback per SeriousWatches; its attachment on the carbon case is not stated. Fixed bezel without an insert (photos). Sold only on a "Canvas leather strap with PVD Buckle" (Zelos), not on a bracelet; Worn & Wound: black PVD buckle and tang; stitching is orange on the Supernova and white on the Moonscape (photos). Dial descriptions from Zelos's colourway text.
