Well I,ve owned my Aerospace for some eight years at least, had the battery changed twice at my local qualty family jewellers at £5 each time absolutely fine no problems though I wouldn,t dream of swimming with a watch of this quality and value on.Its a fabulous watch really well thought out for its aviation role and still looks nearly new with no scratches on its face in spite of a hard life.Definitely one of lifes better purchases especially when you consider my wife purchased a dress for a similar sum to the watch and has worn it about 4 times.!!!
