3 methods on how to use a Caller's GMT watch such as Seiko's SSK series! From tracking foreign time, changing time zones frequently, to tracking three time zones simultaneously, this guide has you covered. You'll even learn how to us a GMT watch as a compass!

We use our DWC GMT watch and Seiko SSK 003 to demonstrate these methods. The Seiko GMT has a 24 hour chapter ring that helps with additional function, but other than that hey both share a Seiko NH34 movement, so function-wise they are nearly identical.

The methods outlined in this video is tailored for a caller's GMT. The same methods can be used with a traveler's GMT by just swapping the roles of main hour hand and GMT hand.
