I've got a Citizen Skyhawk AT (titanium) and it is by far my favorite timepiece. Within hours of getting it I ordered the ZAGG Invisihield for the crystal, and it has saved it from scratches on two occasions, that I know of and probably many more times. This product fits perfectly and goes on easily, no bubbles, etc. For anyone that has one of these, or any other watch that there is an Invisishield for, I can highly recommend them. Apologies if this is not in the right forum, but I know there are a lot of people who love their watches here so I thought I'd put this out there for them.
