Television presenter Conan O'Brien spotted wearing a Rolex

On the set of his late-night program, Conan O'Brien was photographed holding a #GoVote sign alongside a colleague, and sharp-eyed viewers will notice the distinctive case silhouette of a Rolex Milgauss on his left wrist — finished entirely in a matte black PVD coating rather than the factory stainless steel. The Oyster case, bracelet, and crown all appear uniformly darkened, consistent with a professional third-party physical vapor deposition treatment applied after original purchase.

The base reference is almost certainly the Rolex Milgauss 116400GV, the modern generation introduced in 2007 that revived the model after a long dormancy. That reference features Rolex's caliber 3131, a self-winding movement with a paramagnetic Parachrom hairspring and a soft-iron inner cage that together provide the namesake 1,000-gauss magnetic resistance. The green-sapphire crystal — the 'GV' suffix standing for 'verre vert' — is a signature touch that has become the model's most recognized feature, though at this image resolution and angle confirmation of crystal color is inconclusive.

Custom PVD Rolex pieces occupy a genuinely contested space in the collector community. Rolex does not offer factory black DLC or PVD finishing on the Milgauss, meaning any such treatment is aftermarket — voiding the manufacturer warranty and, in purist circles, diminishing resale value. Specialist shops like Bamford Watch Department and Mad Paris have built reputations on exactly this type of modification, and demand from certain collectors remains robust despite traditionalist objections.

O'Brien's taste in watches has historically leaned toward sports and tool references rather than dress watches, consistent with the Milgauss's technical DNA. The blacked-out treatment aligns with his tendency to wear pieces that read as personal rather than performative — a modified Rolex carries cache without the overt signaling of a platinum Daytona.

On the grey market, unmodified Milgauss 116400GV examples typically trade near or slightly above retail. Custom PVD versions are harder to price — the modification cost runs $800–$1,500 from reputable shops, but resale is unpredictable. Collectors seeking a factory-dark sports Rolex generally migrate to the Explorer or Submariner in ceramic, making O'Brien's modified Milgauss a genuinely individualistic choice.
