Does anyone on here do their own 'DIY' for minor servicing? I'm not talking about fully stripping an entire movement, I'm more than happy to leave that to the trained experts! But the more simple (albeit still delicate) tasks like battery swapping, time-keeping adjustments and possibly seal / crown replacing, which would hopefully mean I don't lose my watch(es) for months at a time just for a simple adjustment! If so - are there any decent tools or toolkits that a keen amateur should look for when wishing to do things like that? Obviously there's a slew of cheaply-mass-produced-in-China stuff on ebay, but I tend to like to work with 'proper' tools that are well made (for obvious reasons!) For reference, I'm a fair mechanic (motorcycles mainly), and have an engineering degree mounted on the wall, so I'm reasonably competent at understanding mechanisms and working on them (albeit at larger scales!) Sorry if this topic has been discussed before - I'll do more looking, but I haven't found much yet, I hope I'm not breaking some unspoken rule by suggesting this and insulting everyone!
