Chad, since you own a PAM233 and I am considering pulling the tricker one, I have some questions for you. While I have finally figured out how the day/night indicator works, thanks to you, I have some more questions to you: 1) While I know that the manufacture mvts. of Panerai are not COSC tested, I know they're tested to the same standards (or even better, like the JlC Master Control 1,000 hours) at Panerai. However, I wonder if the accuracy is all over the place as the power reserve lacks to and end (8 or 9 days)? I guess the three barrels make sure that the accuracy stays consistant during the whole power reserve span, but I would like to know for sure. 2) I remember that you once stated that you had an issue with the power reserve of your PAM233 but got it fixed... what exactly was the problem? I mean for how many days could it run? And was the accuracy poor, as well? 3) How long would a Panerai Service Centre typically be to service your watch? And what would the typical cost be if the watch only needs cleaning, lubing, fresh gaskets, polishing/satination, timing etc? 4) Is the superdomed crystal of the 1950ies cases (like the PAM233) AR coated? If so, on the inner, outer or both sides? Or not at all?
