A little customer service story, if you don't mind:
I sent my
Aquatimer into the watch dealer Tourneau (NYC), who then sent it to IWC (Switzerland) for service. It had a few dings in the case, and one nasty scratch. They said they would completely disassemble the watch, clean and oil it, and then polish the case. They said they could not promise that all of the blemishes could be removed.
Six weeks later--that's two weeks AHEAD of schedule--it arrived back at Tourneau. Tourneau then overnighted it to me. The watch had been re-packaged in a new suede bag, protected in plastic, with not a scratch or ding on it. I often complain about the lack of good customer service in today's "your call is very important to us" world. This experience assured that the next watch I buy will be another IWC. Maybe a Portugesier in rose gold.
