Why it works
Adjustable leverage for compatible watch case backs
Set the two working pins to a compatible notch spacing, then turn the case back by hand with controlled pressure.
Key benefits
Why you will keep it within reach
Manual control
The handheld format lets you apply turning force gradually while keeping the tool aligned.
Multiple configurations
Set1–Set5 option labels are available, with exact included pieces dependent on the selected configuration.
Details that matter
Two-pin adjustment for notched watch backs
Two-point engagement
Two pins are positioned into matching case-back notches before turning force is applied.
Compact adjustment wheel
The central wheel changes the spacing between the two working pins on the rectangular tool body.
Check the fit before turning
Both pins should seat securely in suitable notches before controlled hand pressure is applied.
How it works
Simple by design
Check the case back
Confirm the back has two suitable notches and that both pins can seat securely.
Set the spacing
Adjust the two pins until they align cleanly with the selected notches.
Turn carefully
Keep the opener square to the back and apply controlled hand pressure while turning.
