Buying a watch battery used to mean a trip to Timpson’s and a few minutes’ wait. Then, in later years there was the added excitement of a 1 year guarantee. Latterly, this grew into a 2 year guarantee for the battery. Today, I am promised a life guarantee. I am presuming this is for the battery itself, though I am not sure if the shop think that either the watch or owner will come to the end of their lives before the battery itself.
Has anyone else come across this?
