Change ******** Anne Klein watch

Your watch comes with interchangeable bezels, not faces. Bezel is a ring or rectangle (depends what shape your watch has) surrounding a glass.
All bezels are mostly friction fitted,so, to remove your bezel you need to use a strong knife blade and press it between the bezel and the case. The bezel should lift up.
To get the bezel back you have to press it into place.
For changing the strap you have to turn watch upside down and using the knife or lug tool try to squeeze sprigbar end out of the watch lug. Sprinbar is the piece which holds a strap attached to watch. The end of springbar you will find exactly where the strap is attached to watch. Push it inwards and it must come out. The rest is like 2x2.
Good luck.
