Precisely cut for a watch with a 36.5 mm diameter, excellent quality ensured by the use of state-of-the-art precision machines (laser cutting technology) - optimal edge adhesion, very good shape stability. Easy installation! No bubble formation possible on a dust-free display! When applying the film, the air is displaced and it adheres to the display as if by itself.
