Since we are at the topic of GMT watches...
Why is that ExpII and GMT master II referred to as "True GMT" watches?
I don't get it....
hanz079,
The different types of GMT watches:
1) The main hour hand can be independently adjusted forward or backwards (some in 1 hour increments) with the crown or pushers. The date will change forward or backward together with the hands. The 24 hour hand is adjusted is by setting the watch.
2) The 24 hour hand can be independently adjusted forward or backwards (some in 1 hour increments) with the crown or pushers. The main hour hand is adjusted by setting the watch.
3) The 24 hour hand can be independently set to any position with the crown and is not 'linked' to the minute or main hour hands.
4) The 24-Hour hand is not independent of the main hour hand. The bezel is used to keep track of the second time zone.
2) The second time zone is displayed in a sub-dial. Adjustment is like example 1.
No 1 is what most people consider as true GMT watch because you can quickly adjust the hour hand to local time while the 24 hour hand would show the home time.
No 2 is what most GMT watches can do. It is used to monitor a 2nd time-zone, useful if you have children in another time zone and you would like to know when to call them.
