[QUOTE="thor447, post: 3898951, member: 24867"] Post 3 Once I had all of the missing parts pulled from the donor, I cleaned them and began assembly. I am finding it difficult to remember to stop during assembly to take photos, so I don't have much to show here during the process, but there are some decent little videos. [ATTACH type="full"]319382[/ATTACH] This first video was during assembly of the rear side of the watch. It is the critical point of installing the balance assembly. The rest of the rear side of the movement (aside from the automatic works) had been assembled and lubricated. I apologize for the lack of video quality, as I have zero clue about camera settings, so this video was taken using the default options on the microscope camera I use. Installing the balance: [MEDIA=youtube]kbOdRF5vD_0[/MEDIA] Here's a video of it running a few minutes after installing the balance. I am looking at it from an angle, checking the flatness of the hairspring, checking to see that the wheel doesn't appear out of balance and swings true, and getting a feel for the amplitude by looking at how far the balance is swinging in either direction after engaging the pallet fork. It's an interesting angle in the video where you can see the underside of the balance, where the impulse jewel on the underside of the balance/roller assembly engages with the pallet fork, thus running the watch: [MEDIA=youtube]CRnXlYRFKuA[/MEDIA] The last video is the timegrapher reading after regulating it. This was taken after about 10 minutes of adjusting the watch. I got really good results. The next step after this video is to let it run in for about 24 hours. This is so that the lubricants have a chance to cycle though the watch (only where they are supposed to be), and any issues that might creep up due to end shake, side shake, mainspring issues, etc. will come to light. Thankfully I didn't have much to do 24 hours later. I hadn't wound the mainspring since I first assembled it, and I was still getting a pretty good amplitude a day later. [MEDIA=youtube]emNp6H39wGg[/MEDIA] Here's a couple of photos taken today. It was the first day wearing the rebuilt watch. [ATTACH type="full"]319383[/ATTACH] [ATTACH type="full"]319384[/ATTACH] I will take it apart in the next few days to adjust the landing position of the day wheel. It is a little off-center, but not enough to make me not want to wear it today! It didn't appear that way in the original photos, but since the day wheel retaining clip was not installed, it wasn't fully indexing into position. Once the clip was installed, this issue showed itself. It's a quick fix, but I'll address it later. I'm just enjoying wearing this weird retro-looking watch for the time being.
