I have an invicta prodiver that I have been having some probelms with. I purchased the watch new last year and after a month the watch completely quit working. I sent it back to invicta for warranty repair. 3 months later I got it back and it just didnt seem like they repaired it correctly. It worked ok for a while but I think the power reserve is supposed to be 40 hrs or so. If i wear it all day, it will stop working after about 4 hours. I may be lucky if it will make it through the night still running the next day. But, when it came back from the factory, it seems like the rotor is to tight. it doesnt rotate smoothly. My watch winder cant even keep the watch wound. Its like the rotor gets stuck, almost like the screwed the rotor down to tight or the back casing is to tight and is pushing down on the rotor. And the most recent thing that has started with in in the past couple months, it will start running fast. After about 2-3 hours, it is 20 min fast. I have to set it back about every 2-3 hours. Any ideas what is going on with it? It is the NH25A movement in it.
thanks for your help
