Mixed martial artist Conor McGregor spotted wearing a Jacob & Co

Conor McGregor was photographed wearing the Jacob & Co Epic X Chrono in reference EC313.21.SB.BG.C, a piece that communicates its intentions before you read a single spec: black DLC-coated titanium case, black ceramic bezel, skeletonized architecture, and a contrasting green rubber strap that anchors the entire composition.

The Epic X Chrono is one of Jacob & Co's more mechanically credible offerings. The 47mm case houses a hand-wound column-wheel chronograph movement — caliber JCAM16 — with a 50-hour power reserve. The tonneau-inspired case shape, exposed bridges, and X-frame construction give the dial an almost industrial quality. DLC coating on titanium achieves both scratch resistance and a uniform matte black finish without adding meaningful weight, keeping the watch comfortable despite its dimensions. The black ceramic bezel adds a secondary layer of hardness and visual depth that contrasts cleanly against the green strap.

Among collectors, Jacob & Co occupies a specific lane: unapologetically bold, technically ambitious when it chooses to be, and deeply associated with hip-hop and combat sports culture. The Epic X line sits in the middle tier of the brand's catalog — more accessible than the Astronomia or Billionaire, but still engineered in-house and finished to a standard that justifies the price. Reference EC313.21.SB.BG.C, with its all-black hardware and vivid strap, is one of the stronger colorway executions in the range.

McGregor has worn Jacob & Co publicly on multiple occasions and counts among the brand's most visible celebrity associations. His taste runs toward high-contrast, visually aggressive pieces — the Epic X Chrono in this configuration fits that profile precisely. The green strap detail is a recurring McGregor signature, echoing his Irish identity without resorting to obvious cliché.

The Epic X Chrono EC313.21.SB.BG.C carries a UK list price of approximately £22,000, placing it in the mid-range for bespoke independent watchmakers. Grey market pricing for this reference tends to hover near or slightly below retail, as Jacob & Co pieces generally trade at modest discounts outside of limited editions. For buyers who want in-house chronograph mechanics in a case that makes no attempt at discretion, this reference delivers on both counts.
