It is a must take course for anyone daring to work on a Valjoux 7500, arguably the most complex mechanical watch movement. I am now at the first phase, completing the purchases of tools and lubricants needed as well as a ST19 movement to get some practice working on a chronograph complexity before eventually moving to a Valjoux 7500.
I want to thank Mark for making such a great, professional quality videos! Breaking the lessons into just a few minutes long chunks makes the navigation easy. Overall, a lot of value for the money.
There is also a transcript , but it is just a text with no static photos or pictures. Perhaps this will be added one day and sold as a book…
