Crown not screwing down

[Memphisbigdave]

Any suggestions on a fix, other than sending it in, for a Rolex crown that won't "bite" down on the tube? It worked fine, now it won't tighten down to close off the tube. Thanks

Reps are notorious for having poor quality crowns & crown tubes, which results in misthreading..........often within days or hours after delivery. The options are to replace both with gen parts (crowns can be found on ebay & the for sale sections of gen Rolex sites) & gen or Swiss-made (functionally the same as gen) tubes can be found at most watchmaker supply sites. Depending on the particular rep watch case you hold in your hand, the threads in your case may need to be retapped in order to fit either a gen/Swiss-made or another rep tube. Unfortunately, due to the lack of QC & construction variability of rep cases, the only way to know if your case requires retapping is to try to fit another tube. I am not aware of any shortcuts to this.
