Powered by Rolex's caliber 3135 automatic movement with its robust 48-hour power reserve, this yellow gold Yacht-Master 40 with grey dial represents the pinnacle of marine chronometry engineering. The 40mm yellow gold case of reference 16623 g houses a sophisticated regatta timer mechanism originally developed for professional yacht racing, where split-second precision determines victory margins. This unworn example showcases the distinctive grey dial configuration that transforms the watch's presence from nautical tool to sophisticated dress sport piece. The bidirectional rotating bezel, crafted in matching yellow gold with raised numerals, provides the tactical functionality that made this reference essential equipment for serious sailors throughout the 1990s and 2000s.
