This is a complication model featuring a dual time zone and a chronograph that exudes the luxury of a sports watch.
By pressing the push button on the left side of the case, which simplifies the operation of the complex mechanism, you can adjust the hour hand—which normally moves in unison with the other—in one-hour increments.
It has evolved for even greater usability, displaying the departure time with the lower skeleton hand and the local time with the upper hand, and featuring two day/night indicators.
