The Mod GMT collection seamlessly fuses timeless elegance with contemporary flair.

The watch showcases a sturdy 41 mm case and a distinct dial complemented by a striking ceramic bezel. The dial is safeguarded by a cyclops sapphire crystal. Featuring its bold design, this watch strikes a perfect balance between heritage and modernity, making it a versatile accessory for any event.

GMT watch is a timepiece that displays both a 24-hour and a 12-hour timescale.
The 24-hour clock hand has a different color and is geared to turn half as quickly as the 12-hour hands. To put it simply, the 12-hour clock hand completes a full rotation twice a day. Whereas, the 24-hour clock hand spins around only once. The 24-hour watch also enables the user to easily distinguish whether it is AM or PM. Bezel helps to identify the time in 24-hour format.
