Most popular AP watches?
I don't know much about these watches but what are the some of the popular models and their prices?

Faulty screw overnight
Was selling my 5170G and had a buyer for it and was about to wrap the watch for shipping. Before the last farewell I chose to set the time to the buyer's local time. Suddenly I started to hear some rattling inside the movement, I turned the watch over and saw a piece of metal going all over the place. It appears that one screw had got loose and popped out or cut in half.What is funny (well, not really) is that I took the first picture last Saturday and kept the watch in safe until yesterday when I just took a glimpse of it and it was still running perfectly without issues. Then put it back in the safe and today it's as in the second picture. Some might think I dropped the watch or did something humiliating to it, but sure I did not.I don't know if it's a torque issue with screw or faulty piece of threaded steel or whatever, but anyways this one is going back for service, luckily still under the warranty.

one and only PAM
hit by PAM bug...eyeing on of these, PAM372 , PAM422 , PAM587 or PAM673?

Can I pull this off?
Ok, here we go, Ruud Van Indecisive strikes again. I was passing the OP boutique and it was rude not to call in for a mooch. I guess I want to be sure before pulling the trigger on my final PAM. My man pulled out a couple of divers and my eye was really caught by the 389 and 615. The added bonus of these references is the ceramic bezel; personally, I would avoid the new 692 on the basis of a non-ceramic bezel. I like the quirkiness of the Flyback but it bothers me not having a date. In comes the 389, which has a date. I would love either of them and both are very different to what I already have. The 389 is about S$8,000 cheaper (GB��4,500, US$5,600), which is a factor but no deal breaker. What puts me off the 615 is the significant extra service cost and the possibility of the chrono hands becoming misaligned over time. Anyhoo, what you guys think? Firstly, can I pull off a 47mm diver and which one looks the business?

90s Rolex 16700 GMT Master Case Condition
Looking to acquire this particular GMT 16700 from mid 1990s , would like to ask your opinion on the case condition. Is it overpolished? Is it missing any bevel required of this model? Is this a good condition overall?
