Every so often I come across a comment in a for sale ad like this:

"Still has all orginal packing, plastic seals, etc.. And It has an undated warranty card..."

My question is what are the rules about unsigned cards? What's to stop a second or third buyer just filling in the card if there is a problem and claim a warranty even if the watch was purchased well out of warranty. I understand that if the watch was no longer in production for more than a couple of years, but what if the watch is still in production?

 

I have no experience in dealing with OEM warranty claims with Omega, however and for what is worth, other manufacturers require a copy of the sales receipt from an AD as proof of purchase to validate the warranty period - this was my experience with Breitling when they serviced the watch under the warranty period and at no cost to me.
