I had suspected within a couple days it might be running slow, but it really became very evident after a month (good thing for Amazons extend holiday return policy). After a couple weeks it was well into being 3 to 4 minutes late. Totally unacceptable. So I got it swapped out and the replacement seems to be keeping perfect time. As much as I like this watch (I own almost 20 Invicta's) I love blue, but this blue although its a semi-metallic looking color has more of a purple hue to it. Just this shade seems to not really go well with anything and for a mans watch its a bit of an odd color. I don't want to go as far as saying I don't like it, but I don't overly care for it either. I tend to get a lot of comments when I wear most of my other watches, I never get any with this one. I wish the price point (around $150) that I paid would have been lower. I was sucked into the whole "ceramic" thing to find the color does not go all the way through. Its a baked on color, the inside of at least one of the links is black. This is a topic on another watch site about how people were mislead into being told the color went all the way through, therefore the watch was basically unscratchable. I suppose on the fact its a pro diver and good fit and finish, it is still worthy of 4 stars.
