Countdown functionBASELWORLD 2015: The Hamilton Chrono Worldtimer Quartz
All pilots need a chronograph, while aerobatics pilots require particular functions, such as the precise marking of the four minutes corresponding to a freestyle programme – which is why the latter appear in yellow on the dial.
This watch equipped with a quartz movement specially developed for Hamilton also offers a whole series of functions that are highly useful both in flight and on the ground. A simple press on the 10 o’clock pusher switches it between chronograph and Worldtimer functions, a change clearly visible on the dial by means of the mode-selection indicator at 2 o’clock. The 24 timezones are printed on the inner bezel ring. Finally, the model also features a day/night indication as well as a countdown engraved on the bezel.
