Here comes the story about putting everything together. The Rolex 16030 case was delivered with a 3035 movement. The fact that a lot of people remove the movement from the Datejust and use it as replacement in more popular watches, the Datejust parts are affordable. I decided to buy a VS 3135 movement because I had some good experience. It is reliable and most similar to the original 3135. But what I did not know, it is not identical in size to a 3035 movement. To fit it into the case, I have to reduce the diameter of the movement or increase the diameter of the case. Working on an original case is beyond my limits. So, I decided to work on the movement and dremel it. It was a painful process and the first time that I realized that the movement is built from bras.
How did you drembel it?

You absolute monster and genius lol that's certainly one way of fitting a 3135 into a gen 160XX case! How did it hold up after years of wear, still have it?

You're right, that really is an unconventional way of making movement and case compatible.
In fact, I rarely wear the watch. That also gives me the idea of taking it out again.
Yes, it's still running. Just like it was initially. The rate values are good. My biggest concern was that I would spread fine grinding dust in the movement and the movement would have poor rate values in the medium future. But it seems to have gone well.

Yeah, thats what I was thinking when I saw your post on it. Getting that microdust into the movement possibly damaging it but looks like you did a stellar job on it! What a great build, unfortunate it doesn't get much wrist time!
