My first ST36 movement service with impressive results

It's incredibly satisfying to see the positive results after servicing a movement, isn't it? For me, it was my first time doing it—after, of course, watching a few YouTube videos and learning the basics.

I came across a used watch with an ST36 movement that still worked, but barely. The timegrapher showed poor performance, and the case back looked absolutely dreadful under a microscope probably due to intensive wear. Undeterred, I decided to dive in. I began by opening the case and carefully disassembling the movement, cleaning the parts and put everything back in place and of course lubricating. 

I know there are countless posts like this out there, so I won’t bore you with the usual flood of photos. Instead, I’ll just share a select few. I am looking forward to servicing and restoring older watches. I already have a few vintage watches waiting to be serviced

Cheers from Germany,
