Mixed martial artist Aaron Chalmers spotted wearing a Rolex

Aaron Chalmers, best known to British audiences as a cast member of MTV's Geordie Shore before transitioning to professional mixed martial arts, was recently spotted wearing a Rolex Yacht-Master II in Oystersteel, reference 116680 — one of Rolex's most mechanically distinctive sport watches and a model that often flies under the radar compared to its stablemates.

The Rolex Yacht-Master II ref. 116680 was introduced in 2013 as the steel variant of the line originally launched in 18ct gold in 2007. It measures a commanding 44mm in diameter and houses the Calibre 4161, a movement Rolex developed over more than a decade exclusively for this reference. The movement features a mechanical memory and a programmable countdown function with a synchronized countdown — a genuine regatta timer built to comply with racing rules. The bidirectional rotating bezel with Ring Command system links directly to the movement, allowing the skipper to set race start sequences without pressing any pusher. It is technically unlike anything else in the Rolex catalogue.

The white lacquer dial and the bright Cerachrom bezel insert in white ceramic give the 116680 a clean, high-contrast look that separates it clearly from the gold iterations. The bracelet is the Oyster, paired with an Oysterlock clasp and Rolex's Easylink 5mm comfort extension — practical details on a watch designed, at least nominally, for offshore racing use.

From a collector standpoint, the Yacht-Master II ref. 116680 occupies an interesting position. It is one of the more technically sophisticated references in the sport Rolex family, yet it remains less sought-after on the secondary market than the Daytona, GMT-Master II, or Submariner. That relative accessibility — combined with genuine horological substance — makes it quietly compelling to buyers who want a serious movement in a Rolex without paying Daytona premiums. Grey market pricing has historically tracked close to or slightly above retail, depending on condition and period.

Chalmers, who fought in Bellator MMA after leaving reality television, has cultivated a profile that spans celebrity culture and combat sports. The Yacht-Master II ref. 116680, bold in size and backed by genuine complication, reads as a natural fit for that particular intersection. UK RRP was £12,600 at time of listing.
