Thanks again Hobbs,
Dependable for answers as usual.
Regarding the PM you sent me on the 3185 and 3186 movement,
I found out a way to test which movement is equipped without opening the caseback.
Unscrew the crown and pull it out one click (2nd Position)
This position enables you to adjust the hour hand independently without the seconds and minute hands stopping.
Try to adjust it forward a few hours and backwards a few hours.
During the adjustments, if the minute, seconds and GMT hands move abit... it means that it is equipped with a 3185 movement.
For the newer 3186 movement, the minute, seconds hand might creep abit but the GMT hand will not move even a tick.
