Description
The Black Bay GMT gave Tudor collectors the travel complication they had been waiting for, wrapped in the red-and-blue bezel that has signalled "two time zones" since the 1950s. Reference 79830RB runs a 41mm stainless steel case with a ceramic Pepsi insert, and the automatic movement inside tracks home and local time simultaneously — the practical argument for a GMT, and the reason the format has never gone out of style.
