The more we travel the globe, the more we appreciate today’s most alluring multi-time zone watches. Interestingly, since 1937, wristwatches have been able to display time in all of the world’s key 24 cities – known as Universal time. The making of a multi-time zone watch is complex, and takes into account calendar functions, as well as hour differentiations. What’s more, it is not just about how the movement fits in the watch, but with this complication, it is about how it looks – as there are many different ways to present time zones.
