Yeah - its not a 7750... Wear it around, make sure it keeps good time. If it breaks, send it in for fixing / upgrade to an ETA movement, in the end they are still reps and wont last forever, dont beat it like a gen (over winding, other forms of abuse), and you will have something that will last you for a few years.
7750 owners on the other hand, run ok as long as you dont use the chrono (too much, or reset the chrono too far away from the 12). There are sub forums for each movement, you can look at what people have done... You have been on a tear with posts related to your first PAM rep purchase today.... Take some time to read, and look at what others have encountered, done, etc.al, and most of all enjoy it.
