At the end of last year I got a Frederique Constant Yacht Timer GMT, but when it arrived the box was a total mess and on investigation I found that I was not able to set the GMT hand. After several months of back and forth with UPS I took the watch in to get a quotation on the repair for this, for the insurance. The repair quote has just come back but the notes suggest that 'User quickset at wrong timing resulting in damaging of movement components'. They quotation also notes that the date turns over at about 4am, which I was not aware of (as I have never actually worn the watch).
I realise that setting the date between 9pm and 3am is a bad idea, and I am reasonably sure I didnt do this when the watch arrived, although proving that is now impossible. But even so, would doing this affect the setting of the GMT hand as well? Would impact damage really not cause this type of problem with setting the GMT hand?
