【Only for one type of watch】 What you need to pay special attention to is that this adjustable watch opener is only suitable for watch cases with notches, not for watches with backs that open with a bending tool or screws; only suitable for round watches, not for square or other types of watches.
【Function of the watch holder】 With the watch holder, the gripping surface is larger, which can generate more torque and help you open the back of the watch more conveniently and efficiently. In addition, it is more stable to use the watch holder than to fix the watch directly by hand, which can effectively prevent the watch and hand from being scratched due to the watch slipping.
【Anti-slip films】 Using the anti-slip film can increase friction to prevent the watch opener from slipping on the watch, and also protects the watch from the tool leaving scratches on the watch. Make sure to use the anti-slip film, otherwise there is an increased risk of the tools slipping and scratching the watch.
【Surgical technique】 Note: Press down and rotate the opener slowly, otherwise the clamps tend to slip and fail to hold
