Classic chronograph with simultaneous display of time in two time zones. For the second time zone, add. a window in the form of a world map. In addition to a stopwatch for 24 hours with an accuracy of 1/20 of a second, the clock has a countdown timer function and an alarm clock [works for time in add. window at 12 o’clock]. The bezel is marked with city codes – for the world time, and on the outer ring of the dial there is an hour difference with a zero zone – very convenient for quick access to the time in each time zone without switching to a separate mode. The current date is displayed in the format of the day of the month and day of the week. The bezel received an ion-coated surface to prevent scratches.
