Frequently asked questions
Which die size do I need for my watch?
Measure the diameter of the notched ring on your watch's case back and pick the matching die of the case back opener: 18.5, 20.2, 22.5, 26.5, 28.3 or 29.5 mm.
Will it open a snap-on case back?
No. The case back opener is for screw-down backs with notches around the edge; snap-on backs need a case knife instead.
How does the opener work?
Fit the die over the notches of the case back, place the handle across the die and turn it anticlockwise to unscrew the back.
What comes in the box?
The case back opener set holds one T-handle and six dies in a fitted display box.
