These guys are real watchmakers.
I gave my wife an older 9K Rolex years ago. Apparently, these watches were not fashionable. Now that we are way past being kids, my wife asked me to get her watch serviced. Hamilton Jewelry, the Rolex dealer in St. Louis closed a while back. These folks were recommended to me and I am glad.
They correctly identified the watch and approximate date of manufacturer. This watch was made around 1940. When I picked the watch up today, it looked like it should be in a showcase. A nice deep polish on the bark band. The case is fabulous and it keeps great time.
When my old Oyster needs service, I will take it to these folks, too.
