World Time Master Louis Cottier
Although the standard of world time was formulated uniformly, it was not until the early 1930s that what we call today the world time watch appeared, and its inventor was the genius watchmaker Louis Cottier. According to some available information, Swiss watchmakers have been trying to make clocks that can display the local time of different cities. The earliest one was a double-sided pocket watch made in 1780. The back of the watch indicates Time in 53 different places.
Heures Universelles (HU), the world time zone watch mechanism invented by Louis Cottier in 1935, can be said to be a pioneer. Since then, most of the world time watch creations will use this as a reference or reference. As you can see in the design manuscript of Louis Cottier, his design uses the small central hour and minute hands to indicate the local time. In addition, the outer circle or dial of the watch is engraved with the names of different time zones, countries and cities in the world. The inner circle It is paired with a 24-hour inner circle of time to display the time in different world time zones at the same time.
The biggest difference between Louis Cottier’s HU mechanism and the previous world time zone pocket watch is that its local time and world time zone time are displayed on the same side of the watch, instead of having to be set on both sides of the watch. Some of the earliest watch factories that made World Time, including Patek Philippe, Vacheron Constantin and Rolex, adopted this concept of World Time by Louis Cottier, and finally (1959) this patent was owned by Patek Philippe and obtained exclusive rights.
