Should I be worried about my A7750

[Drulee]

So I had a movement swapped from one case to another, but now it is running 2 minutes fast a day. Before it kept near perfect time, and nothing went wrong during the swap. Does it just need regulating, or is it a sign of impending doom

It's an A7750 GMT movement. What do you think? And if it just needs adjusting, how can I go about doing this?

Thanks

Your watch will run faster as the oils evaporate. Are you certain this has not been coming on for a while?

2 minutes per days can be normally compensated regulating the watch... just do it ans check if the new precision remains constant...

Really? I would have thought that this would lead to it running slower, not faster, as there would be more friction. Anyway, it is a brand new movement, so I'd hope it has not been coming on for a while

Will be doing that this evening, thanks
