路One watch I wasn't intending to change the battery myself is the Microtimer, not least because the back is held on by tiny screws.... and now of course the battery indicator has come on - with the TAG service centre and anyone else who I might trust to do it. So I guess I just have to hope the battery saver keeps it going long enough, or failing that if it goes completely I'll have to take my screwdriver in hand and have a go...
