I've been watching Watch Repair Channel on YouTube and am subscribed to that. I really like Mark's teaching style. I have been collecting watches for about 10 years. I had to stop actively collecting for financial reasons for a while but my collection has doubled in the past year and now I have to learn more. I've always had to tinker with whatever I was interested in, taking things apart and putting them back together and building things has been something positive I gained from my dad. So now I need the knowledge to work on my watches new and vintage. Thank you for the community of help here in this forum!
