Next time you buy a watch with a date complication, pull the crown all the way out and advance the time until the date changes over.Just an update - I have dropped the case. Honestly, its totally depressing and there isn't really much I can do. Up until about a week ago, I was sure that this was not a problem that I caused. But in the last few days I am trying to remember the order of the actions I took on a specific day five months ago, and the reality is that I can't guarantee or prove that it wasn't me. All I can say is that I have many watches with a date complication, and the only one that has had any problem at all, arrived in a box that looked like it had been used for soccer practice and had a problem within minutes of opening the beaten up box. I am not denying that 'this damage cannot be caused by mishandling' but its still really frustrating.
I am pretty sure that this was not the seller. Throughout this process, the seller has really been the only person supporting me in this, and the watch had been opened to include more bubble wrap (thank goodness for that!) but the watch had stickers on, etc, the seller was open an communicated well, and they had a great review rating.
I don't have the watch at this point as it's still in the repair centre, so I can't verify the issues around how it functions normally and whether it really is broken at this time, but the GMT hand did not move or set at all when I checked it, and that's a pretty fundamental issue which is clearly a problem. I am also not sure about the whole 'date clicks over with the GMT hand'. I have seen a single YouTube review that says that this is how it functions, but it seems such a ridiculous design flaw that I really don't believe that this is the case and I haven't been able to verify this 'feature'. If true, since I set the GMT at -8 hours from my local time, the date will essentially be wrong for 1/3 of every day. There seems absolutely no reason for this to happen.
Anyway, many thanks for the feedback. The real big frustration here is that UPS managed to mess up the delivery at several stages (they refused to deliver first time even though I paid the import tax because their system didn't show my payment, then the box was totally messed up, then they stonewalled me......) and after 5 months with fighting for some kind of resolution or getting them to take responsibility, I have had to drop the process and I am out about US$650 for the repair too. I will think twice before getting a watch delivered internationally in the future.
The movement in your FC is possibly the same as the hacked Selitta used by Alpina in their GMT. The local hand can be advanced an hour at a time without impacting the date because the date is tied to the GMT.
