Citizen watch company celebrates its centennial year with a GMT world time watch, in collaboration with the Japanese accessory brand Porter. The Citizen x Porter GMT World Time uses an Eco-Drive movement that’s solar-charged and will maintain its charge for six months at a time. So if you like to switch between watches you won’t find yourself constantly resetting your watch before you pick it up. (And you won’t need to replace the battery for decades.)
With the rotating city ring dial and a GMT hand, you can keep track of multiple time zones at once. The Citizen x Porter GMT World Time features 200 meters of water resistance and is available in black or silver, and you can keep it on a matching steel bracelet, or switch it to a khaki or black nylon strap.
