I got my watch back from being serviced and fitted with a new battery but once fully charged (ie 30secs) it only lasts a week before it goes down to 20secs.
Anyone have any ideas how long theirs lasts from a full charge? I mailed the place I got it changed and the wishy washy reply was they are all different. Yeah ok but different by a day or a month, give me a clue.
Oh and if anyone wants to know how to modify a watch winder to charge kinetics I've done it and it's easy so don't go buying a modified one for twice the price.
