Hi all. I just acquired a circa 2009 657. I love it and it's in great shape, but the bezel is quite stuff and very difficult to turn. I once had an 857 (with essentially the same sort of bezel) and it was much easier to turn. Perhaps there is gunk under the bezel or something, but I don't feel comfortable removing it myself.
Is this something a competent local watchmaker can handle or should I send to RGM? The watch keeps decent time and I otherwise probably wouldn't send it for service yet, though the watch is 5+ years old. Thanks for your thoughts!
