Our very best Rolex case opener, but now offered with a case holder featuring nylon covered pins that make it unnecessary to use a cloth between the opener and the precious watch case. This adjustable case holder simply slips into the groove in the base of the opener. It's fast and convenient. Case holder is made of aluminum and the watch may be inserted into the holder, and then put into the wrench to be removed. The case holder may be purchased to retrofit your original CWR-650.00.
