Hi, I bought this watch a year or so ago, secondhand. Although I like it tremendously, it doesn't get a lot of wrist time. Today when I went to charge it (shake it), I noticed a sound that seems like the rotor spinning freely or the mainspring unwinding coming from the watch. It never used to make that sound. It is running and has been for a couple of hours with no trouble, but any time I shake it, it still sounds the same.
I think it has a 7750.
Does anyone have any suggestions on what it might be, or how I should proceed?
