The History of Dual Time watches & TWELF-X SKY 3 time Zone

by Pamela Tan May 6, 2026

Timekeeping has always been tied to exploration. Long before smartphones and GPS, watches were essential tools for travellers, sailors, and aviators who needed to keep track of time across regions. The concept of a dual-time watch, a watch that could display two time zones simultaneously, emerged in the mid-20th century, as global travel became more common and aviation connected continents like never before.

The first true dual-time watches appeared in the 1950s, catering to pilots and international businessmen who needed a reliable way to track “home time” alongside “destination time.” These early models featured a secondary hour hand or a rotating bezel that allowed wearers to adjust for a second time zone without resetting the main dial.

Even in the digital age, dual-time and multi-time zone watches remain relevant. For frequent travellers, professionals working across countries, and adventurers who move between continents, they offer instant readability without relying on electronics. Beyond practicality, they represent a sense of freedom, away from the phone and the ability to stay connected to one place while exploring another.

Building on this legacy, the TWELF-X SKY Collection takes functionality a step further with a 3 time-zone display, designed for modern jet setters who traverse the globe.

How the 3 Time Zone Function Works

Main Dial (Local Time): Displays the current time in your present location.
24-Hour Inner Bezel: Lets you track a second time zone with precision—perfect for keeping “home time” while abroad.
Rotating Outer Bezel: Adds a third time zone, which you can set by rotating it to align with your reference city or UTC offset.

This clever combination of a rotating inner and external bezel, and a robust automatic movement makes the TWELF-X SKY Collection one of the few timepieces that can track three zones simultaneously. In a world that is more connected than ever, the need to balance multiple time zones is no longer reserved for aviators. Whether you are hopping between meetings in New York, London, and Singapore, or simply staying in touch with loved ones across continents, the TWELF-X SKY Collection ensures you’re always on time, wherever you are.

The TWELF-X Sky watch is ideal for pilots, business travellers, or anyone who lives a global lifestyle. If you are looking for a watch that honours the heritage of dual-timekeeping while embracing modern exploration, discover the TWELF-X SKY Collection that is for travellers who live beyond borders.
