As a watch collector, allow me to refute some other negative reviews, like it doesn't fit.WRONG. Follow the directions (which could be better). Yes, it will not fit if you don't remove the white strap interface. Mine came off with the old strap no problem, so all I did was slip new strap into watch case end and insert with screw. It was really nice they included the special tool and extra screws.I bought this because the keeper on the original strap just broke, leaving the strap end sticking out. The new strap has TWO keepers, nice! Another pro is the length. The old strap was barely enough length to fasten it around my wrist above the wrist bone as recommended. This one is slightly longer. No more trying to slid the keeper over the remaining millimeter of strap once it was buckled. The strap itself is at least as thick as old original, and appear identical in texture and width.
