Out of 70+ reps over the last 3 years, maybe 10 have had problems. 2 that were DOA and replaced by dealers. 1 or two that quickly had problems and were replaced by dealers, and maybe 5-6 that had issues such as stopping, chrono issues, bezel issues, etc. that my watchsmith was able to fix at a very reasonable price.
Most of my early reps (except for two) run perfectly, considering that they are rarely worn. Quality has definetly improved this year. Movements are better, chrono's work, bezels are not a problem.
This is now the golden age of reps..... and the best is still to come.
