How to use
Select the die whose diameter exactly matches the bezel or the back to be closed. Place the die on the press piston, position the watch in the centre of the platen and gradually lower the lever: the spring distributes the pressure evenly around the entire circumference. Check the correct seating of the crystal or back before releasing pressure.
Quality and durability
The solid steel structure guarantees perfect rigidity and great longevity, even in professional use. The spring keeps its return force over thousands of cycles. The plastic dies prevent scratching the case or the crystal.
Frequently asked questions
Can a sapphire crystal be fitted?
Yes, the fitting is identical, but make sure to use a die that exactly matches the crystal diameter to avoid any pinpoint stress that could crack the sapphire.
How to choose the right die?
Measure the outer diameter of the crystal or back and choose the die whose diameter is the closest, without exceeding that of the case.
Is the press suitable for screw backs?
No, screw backs require a pin wrench or a specific vice; the press is dedicated to snap backs and crystal fitting.
