@@CatalinEnache1502 I have more experience now, but when I was starting out I discovered that the 2789 has two springs in the calendar that the 2789 1 does not have. And the spring that you mention that is not original broke a lot for watchmakers at the time. I imagine that they improved it for that reason. It's a good video, the images are good. Greetings from Spain.
@@MrDavidoff36 indeed! I found a NOS part on eBay after a lot of research but it went quite well. Unfortunately I was in hurry to fix it and did not record the process :)
Goog job. La 2789 es más difícil que la 2789-1
