BaisidaiRolex Watch Repair Tool - 5537 Back Case Opener, Hand Held Watch Case Remover Kit

Tool is very well made. It fits my Sub and also my Parnis watches perfectly. If you like to work on your Oyster back watches this is a must have.

Prefect fit to remove the back of my 1550 Rolex

This watch back opener is very well built. Considering I almost never work on watches that have the Oyster type back, I like how this was fairly inexpensive and I was very surprised at the fit and finish of this set. Well worth the money.

The teeth aren't very sharp. Poor quality steel. Buy quality if you want something that would last. It works but you have to be extremely precise and careful, significantly more so than a traditional screw down which shouldn't be the case with oyster casebacks.

good quility need larger sizes most of them are just to small for mens watches out of all six only one can be used.

Not sure if I got a bad one but the biggest ring that was closest to fitting (No. 5) did not work on my authentic Rolex 116710LN. Even with some significant pressure applied, the teeth did not line up. Was afraid of ruining my caseback if I applied any more pressure. Also, the finish on the tool is not as smooth as the ad makes it appear.

I like the fact it fits perfect, I only need the 29.5 but for the price it's worth it to have the other 5 chucks just in case.It does work for the Rolex Oyster Perpetual DayDate 18238 and others!! (36mm case dial)
