Definition
Collector nickname for a red-and-black bezel, especially associated with certain Rolex GMT-Master II references. Coke is the enthusiast nickname for a red-and-black GMT bezel, especially associated with certain Rolex GMT-Master II references. Like Pepsi, it is community shorthand rather than an official Rolex model designation.
Why it matters
Coke is useful collector shorthand, but reference number, bezel/dial configuration and generation remain the reliable identifiers; the nickname should never replace the actual watch specification.
