World timers heritage

Not only was the time once different between countries, even neighboring cities needed to set their clock differently. The need for a unified system emerfed in the late 19th Century, after the industrial revolution. In 1878, the Canadian engineer Sandford Fleming proposed to divide the globe into 24 time zones wherein the time would be the same. It was only in the early 1930s that the Genevan watchmaker Louis Cottier invented a watch displaying the time in all 24 time zones at once. In 1990, Girard-Perregaux presented its first world timer wristwatch and, in 2000, dedicated a whole collection to world timers : the WW.TC.

The Calibre GP03300

The Calibre GP03300

The in-house GP03300 self-winding mechanical movement supports a unique coupling mechanism that drives the rotating ring with a military-style 24-hour scale on it, allowing to always know what time is now in any of the 24 cities represented on the stationary outer ring.
