You're not going to get a good idea with one rep, but I've been buying and selling for 2 1/2 years, probably 50-60 reps totally through my hands.
Two needed a service to fix an issue (I only got one fixed, I sold the other needing fixing).
Two were less than perfect but worked (issue disclosed when I sold them).
One has a tiny issue but I can live with it (if you alter it the wrong way the minute and hour hands end up way out of alignment).
Oh, and I had the tube trimmed to remove the screw in crown on my VSF Seamaster when it stripped it's crown thread, done for free by Reece
