I wonder what's this MAINTENANCE II

I doubt it, the movement would have been serviced by highly trained Tag/Heuer watchmakers no doubt, very expensive though.COA, replacing chrono hand. OP asked for all new or refurbished hands, got just the one.
Totally outrageous prices, makes me feel sick to think what these "repair & maintenance" men have done to the insides of this watch, after seeing the disgusting job of the outside. No wonder the "case refurbishment" was relatively low priced, they must have an Orang-Utan with a selection of hammers doing the case work.
Said red-furred apprentice failed to catch it before it fell into the OUT tray, I think.The case was probably tossed to an apprentice.
Don't worry, there are NO "new hands". I just received my watch back, send to me from NJ, without any earlier phone or e-mail notification, and - surprise, surprise! - the watch basically was returned exactly like it was before. Looks like they tried to polish the case, with limited success. Sides looks better now, no dings or scratches, however back of it looks exactly like it was. I think I'll take sandpaper in my garage and fix that myself. My biggest disappointment though comes from the fact that they did nothing to the hands. I still have a brand new, bright orange second hand and two other hands with broken, partially gone lumen. Together this looks nothing like "the same appearance as the day you bought it" - quotation from their own website.just make sure the "new hands" you receive are the correct ones for this model, the failure to replace all the hands makes me fear they do not have those hands, otherwise why the partial exchange ?
afraid this isn't over yet and sadly might turn out like predicted - but I hope I'm wrong.
I sent a letter to that nice lady in NJ, who told me to send this watch to her. I hope she will respond and offer to me some kind of a solution.... Either ask for a full refund, or get them to complete the work in a proper manner. Do Not Touch The Watch Yourself!!! This will invalidate any work done already by them, and you will regret that.
Complain, complain, complain...
I don't see any "complain boxes" over there, however I found another interesting thing. Let me quote:... complain on their website (if possible)...
Not true, as anyone who has dealt with the public will know. But irrelevant in this case....
There are not two sides to this coin, the customer is always right.
