Hi, in this video I'll try to fix another mechanical chronograph watch. This is non-working, rusty, and needed small repairs, as usual for me.
I like tinkering with cheap vintage watches. But I always face parts availability issues. Sometimes replacement parts are not available, or even when I can buy them, the cost may be unreasonable.
This movement is Valjoux 7750. I think this is the most tinkerer-friendly chronograph movement. Since this is a very popular movement, there is a lot of good information on the Internet. Although the watch/movement is a bit expensive, we can buy replacement parts easily and reasonably. Also, there are a lot of Chinese "clone" movements. If we don't mind (I mind though), we can replace broken movement with clone movement cheaply.
This is a kind of part 1 of the video series. I managed to fully disassemble, clean, lubricate, and re-assemble. However, this still has some issues. I'll do it all over and try to make this better later soon. If you liked this video, like, comment, and subscribe to my channel!
