Worldtime Watches Ensure Punctuality at Global Appointments
In the early 20th century, as international travel and global communication became more prevalent, a Swiss watchmaker named Louis Cottier devised a solution for tracking time across borders. The result was the invention of the worldtime watch in 1931, marking a significant advancement in the field of horology [3].
A worldtime watch is a unique type of watch designed specifically for international travel and global communication. It features a rotating city ring or disc that lists major cities representing the different time zones, and a 24-hour ring that rotates in sync to indicate the current time in each time zone relative to the local time [1][4]. By aligning the local city with the local time on the 24-hour scale, the wearer can read off the corresponding time in any other city on the dial [2].
The worldtime watch offers several key features. It provides a simultaneous display of all 24 time zones, allowing quick reference to global times with one glance. A city ring or dial indicates the principal cities for each time zone, while a 24-hour ring differentiates between day and night hours in each zone [1]. Mechanical complexity often showcases traditional watchmaking art and craftsmanship, such as enamel work or laser engravings on the dial center, making worldtime watches both functional and artistic pieces [1].
Some models operate the world-time function via a bidirectional crown that allows easy adjustment of the reference city and time without stopping the watch [1]. Innovative designs, like the SpaceOne WorldTimer, use rotating discs instead of traditional hands, where separate discs show seconds, minutes, local 12-hour time, and world time zones with city names and a 24-hour scale, all under a domed sapphire crystal for enhanced readability and aesthetic appeal [2].
In modern times, many worldtimers have a pusher that advances both the hour hand and the city ring together for convenience [1]. The worldtime complication is mechanical and independent of the chronograph or other features found in multifunction watches.
In essence, a worldtime watch provides a mechanical and elegant solution to tracking time globally, combining practical functionality with sophisticated craftsmanship. It operates by aligning a city or time zone with a corresponding 24-hour scale to read the current times worldwide, serving both as a tool for travelers and a showcase of horological artistry [1][2].

A worldtime watch is not only a functional tool for international travel and global communication but also a testament to traditional watchmaking art and craftsmanship, showcasing enamel work or laser engravings on its dial.
Modern worldtimers often come equipped with convenient features like a pusher that advances both the hour hand and the city ring simultaneously for seamless adjustments.
