Mixed martial artist Dustin Poirier spotted wearing a Jacob & Co

Dustin Poirier, one of the most accomplished lightweights in UFC history and a two-time interim UFC Lightweight Champion, was recently spotted wearing a Jacob & Co Epic X Chrono in titanium with a black ceramic bezel, reference EC313.20.SB.RR.B — a piece that reflects the same mix of technical discipline and visual aggression that defines his fighting style.

The Epic X Chrono is one of Jacob & Co's most architecturally distinctive sports watches. The reference EC313.20.SB.RR.B measures 44mm in grade-5 titanium, delivering substantial wrist presence at a relatively low weight — a meaningful consideration for athletes conscious of physical comfort. The black ceramic bezel adds a layer of hardness that titanium alone cannot provide, resisting surface wear far more effectively than conventional metal. The chronograph function is driven by the in-house JCAM37 caliber, a manually wound movement with a column-wheel mechanism and a 50-hour power reserve, visible in full through the open-worked dial and exhibition caseback.

The Epic X line debuted in the mid-2010s as Jacob & Co's answer to the high-horology sports watch segment, drawing structural inspiration from industrial frameworks — its X-brace dial architecture is immediately recognizable and has become a signature of the collection. Unlike many Jacob & Co pieces that lean into diamond pavé and colored stones, the Epic X Chrono in this titanium and ceramic configuration represents the brand's more restrained, technically focused side, appealing to collectors who want mechanical credibility alongside the name recognition.

Poirier, who retired from active competition in 2024 following a storied career that included victories over the likes of Conor McGregor and Dan Hooker, has built a public image rooted in authenticity — he and his wife Jackie founded The Good Fight Foundation, a Louisiana-based charity with genuine community impact. His watch choices tend to reflect function-forward luxury rather than pure ostentation, and the Epic X Chrono fits that profile well.

At a retail price of approximately $23,000, the Jacob & Co Epic X Chrono ref. EC313.20.SB.RR.B occupies a competitive space in the skeletonized sports chronograph market. Grey market availability keeps pricing relatively close to retail on this reference, making it one of the more accessible entry points into the Jacob & Co mechanical catalogue.
