Some time back, my 3776 (in the Vintage line) stopped winding at the crown. I got lazy and just set it on the shelf figuring I'd get to it later.
Well, as the one year anniversary of its purchase got close, I decided I should at least attempt warranty service.
I wrote a short letter explaining the problem, packed the watch (sans strap) as the directions suggested, and included a $20 check in the package. Within a few days I received a postcard with a picture of my actual watch and instructions to go online to check the progress of the repair.
On Sunday I received an automated phone call from UPS informing me that a package would be delivered Monday and would require a signature.
I checked online and surely enough, the Invicta service site reported that the repair was complete and the tracking number indicated that the package was out for delivery.
This entire process took about 4 weeks. I wore the watch to work today and it looks fine, runs fine, and I'm quite satisfied.
I don't know if the Invicta service department has gotten much better lately, or if there never was a problem to begin with. This is the first time I've had to send anything back. But if they were to send me a survey, I'd rate them 10 of 10.
