I have purchased several of the lifetime battery guarantees quite happily to sell these guarantees And take your money but I took two of my watches to Timpson’s in Sainsbury’s Blackpool I was told that one of my guarantees did not Match the watch and I said look at it again because I’ve been using this guarante for five years without agreeing with me or saying anything just took my watch and said come back in 20 minutes now the chap you have in there Mark could certainly do with going on a customer service course as manners are free However Timpson’s have honoured the lifetime watch guarantee and the batteries have lasted a good while and always done a good job on replacing the batteries
