Just a small update:
Me and Doc both received a watch that (probably) had a daywheel gear issue. Our watches had low power reserve (about 12-18 hours FULLY wound). I noticed that the PR was always dying during the day change, which happens between 12-2am. Otherwise my watch was keeping excellent time and functioning normally. This might be characteristic problem for SOME Aquaracer day-date chronos, or just a bad coincidence. PT said that he hasn't heard of any problems (besides mine) though.
I thought this info would be important to know (both dealers and members).
Our watches came from different dealers. Don't know how Doc's dealer will take care of the issue, but Precious Time will replace mine (being a top-class dealer that he is). Actually my replacement is probably here by Monday.
