Titanium version of the Spearfish Dual Time, a big-date and second-time-zone watch in the Spearfish case. The first batch (Sky Blue, Ocean Blue and Spark open-worked sapphire dials) was listed on 2 April 2024 and went on sale on 8 April 2024 alongside two forged-carbon-cased versions (Spearfish Dual Time Carbon, a separate model); the solid Meteorite and Gunmetal dials followed on 28 January 2025. Spark and Sky Blue were still for sale at Zelos on 2026-10-21, so the model is in production; Ocean Blue, Meteorite and Gunmetal were sold out and are recorded as limited. Zelos states no edition size; the caseback photo used on the 2024 listings is engraved "063/100", but nothing says whether that numbering is per colourway or for the series, so limited_to is not set. Launch price US$1,849 (Fratello, Worn & Wound); the store now lists $2,199 for all five. 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 identifies the module as Technotime's; Fratello gives the base as 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 (lume-printed numerals) and a sub-dial at 6 whose own hour and minute hands show a second time zone ("independantly adjustable and follow 12 hour rotation", Zelos) over a lumed world disc that turns once a day as a day/night indicator; Fratello describes it as a 24-hour hand. Case: "Ti with 1200HV Hardened Coating" (grade not stated), bracelet "Ti 1200Hv hardened with updated Quick Adjust Clasp". 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 12.5mm total is Fratello's ("12.5mm (thickness with crystal, 10mm without)"). Crystal: Zelos says "Vintage style domed Sapphire crystal with inner AR coating"; Fratello calls it "box-type double-domed" and Worn & Wound "boxed", so it is recorded as box-domed. Titanium display caseback with a sapphire window held by four screws (Fratello; Zelos's caseback photo). Case finish brushed with matte bevels (Fratello); fixed bezel without an insert (photos). Bracelet: three-row titanium (Fratello), solid end links (SeriousWatches); Fratello says the quick-adjust clasp is "intuitive on the fly", positions not stated. Fratello weighed 105g sized to his wrist (not an unsized figure, so not recorded). Dial descriptions are from Zelos's colourway text. The Ocean Blue's main photo is named "2Yellow" on Shopify but shows the blue dial. The three 2024 listings share one lume photo (not attached, since it can't be tied to a colourway) and one caseback photo (attached without a variant).
