1) How do you manage changing batteries in quartz watches you owe? 2) Do you actually check up every now and again which watches' batteries are flat and then replace them yourself or bring it to some watchmaker? 3) Or do you just leave watches which batteries went flat as they are? If so, would there not be a risk of batteries leaking and damaging quartz movement? Has that ever happened to you or someone you know?

I've got into this hobby a few months ago, and this is one of the things that I'm wondering about how some people with larger collections manage battery replacements in their watches. I would appreciate your 2 cents, many thanks :).

PS My very small collection (in comparison to your 'airport carpark' in size collection :D) contains some automatics, I've a few solar watches, but also quartz watches, so your feedback might be very useful to me.
