About this reference
The Jacob & Co. Epic X Chrono Black Titanium Only Watch 2021 edition, reference EC313.20.AA.AA.ABRUA, is a unique piece produced specifically for the 2021 Only Watch charity auction. This reference features a 47mm case constructed from black DLC-grade 5 titanium with a yellow gold bezel and pushers, distinguishing it from standard production models. It is powered by the JCAA05 skeletonized self-winding chronograph caliber, which utilizes a column-wheel mechanism and offers a 48-hour power reserve. Collectors value this reference for its one-of-one status and the specific "Only Watch" branding on the sapphire crystal caseback. While standard Epic X Chrono models typically trade between $15,000 and $25,000, this unique piece sold at Christie’s in November 2021 for 25,000 CHF. Because it is a unique execution, it does not have a broad secondary market price bracket, though its value is tied to its provenance as a singular auction lot.
