TweetI too am into watches, not a freak about them, but do have several. I have not done specific research on Invicta bit do know they are supposed to be of decent quality. If this crystal broke that easily, to me it sounds like a defect.
Be careful about ordering on-line. Yes, it appears you can save ALOT of money but be leary of the vendor and read the fine print. Many of these vendors are not "approved" by the manufacturer so the manufacturere will not honor any warranty.
