This TAG made it all the way from South Korea (well, it only said Korea on the parcel, but I doubt many people in North Korea have a TAG TwinTime 😉 ), and is in need of a service.
The TAG TwinTime has an extra hand, that turns once every 24 hours, and is the one that drives the date change when it is at the top of the dial. The minute hand works as usual, but the hour hand can be set forward an hour at a time to adjust for different time zones. Nice to have when you travel quite a bit!
The case back is nicely engraved, as you would expect from a TAG.
The plastic case ring doesn’t float my boat, and TAG should hang their heads in shame for putting that in. It works of course just as well as a metal ring, but please…
Dial and hands look very good.
I first thought that the dial had been restored before, but then checked on another TAG that I have in the workshop. These grinding traces on the back of the markers are normal for TAG dials.
The bottom plate with the GMT mechanism.
The auto winder taken apart. The mainspring doesn’t look too bad, but I will of course put a new one in.
This little wheel has a spring and 12 notches, and is the one responsible for the hour hand being able to jump in one hour steps. Click on the photo to enlarge it.
The rest of the movement is as per ETA2892
The keyless works.
The new mainspring has arrived.
The barrel bridge put back together.
And the base movement is back together and ticking.
That doesn’t look too bad at all. After a day or two, I will adjust again, so that I get +1s/day in a mix of three positions.
The bottom plate back together.
The dial and hands go back on.And the watch is back together and ticking again.
