The GMT 24 Hours by Perrelet : Dual Time Zone Watches

While most GMT models opt for a second hour hand, the GMT from Perrelet utilizes a handy hour window in the 9' position providing the wearer with instant knowledge of the second time zone they are tracking. The pusher at 2' easily jumps the second time zone forward one hour. While all dual time zone models provide the same information, the Perrelet does it ease and elegance!
