About this entry
80% of key specs known. Missing: weight, hardening, crown.
Oak & Oscar's first chronograph (announced October 2017): manually wound, column-wheel flyback chronograph (Eterna 3916M; the brand quotes 60h, 25 jewels, 4 Hz) with running seconds at 9, a stacked register at 3 tracking elapsed minutes and hours, and a colour-matched date at 6. Brand specs, the same on all three listings: steel case of 40mm, "14.5mm case height", 46.4mm lug-to-lug, 20mm lugs, 50m, double-domed sapphire with anti-reflective coating (side not stated), light grey wrapped tachymeter scale, brushed applied baton indices with BGW9 in their grooves. The 14.5mm is recorded as the total with crystal: the Jackson Big Eye page gives the same case as 14.0mm, 14.5mm at the top of the domed crystal, and Fratello says the Big Eye has the Jackson's footprint. Display caseback per the brand's movement photo through a caseback marked "sapphire". Delivered on two Horween straps (brown and an orange rally strap), no bracelet. Limited to 400: 150 grey, 150 navy and 100 charcoal PVD (grey-toned charcoal dial in a black PVD case); Worn & Wound gives the pre-order prices ($2,650 steel, $2,850 PVD) and the final MSRPs the store still shows; all sold out on 2026-10-25. No weight published. The no-date Jackson Big Eye uses a different caliber and is a separate model.
