I posted this one when I first picked it up back in July. Came in parts and the automatic works was put together wrong. I learned a lot on this family of movements and really am happy with the outcome as well as the journey. First I will post how it arrived, the for now final, the parts I sourced for replacement,  and the latest disassembly for service in case it helps someone else. I had to match every part to the tech sheet and found only 1 missing screw, but the calendar and date rings were toast on arrival. They were good for practice during assembly because they only had the paint removed and I separated the hour wheel from the day ring so that I could work on the calendar and day advancements and see the bridges on the dial side.DSCN54184.thumb.JPG.b07c36af059d514914f5105079910706.JPGDSCN54194.thumb.JPG.b134264a07778c74798686cc3a9cbfc6.JPGDSCN54822.thumb.JPG.7a43d850bfbd557ec69a2264edaff6ec.JPG20231023_1906222.thumb.jpg.ece7ee9a2434957ae0d0a04538fcbe2c.jpg20231023_1908312.thumb.jpg.4caeb80fd5d5c7715a7b9809b3733de8.jpg20231023_1906592.thumb.jpg.e0c68f5973b50dc942b650df6b5a4a12.jpg

The original bracelet is a little different with a single link style and needs a little adjustment to get the end covers to lay flat.

The watch has been going for about 22 hours with more than 14 hours on the wrist. I am never sure when a full wind is reached on these that have a manual wind function as well. The watch has gained a bit over that time and the timegrapher numbers are pretty decent with not much delta on the horizontal for either the beat error or the Amp. On the vertical 2 of the 4 had good numbers and deltas on the Amp and beat error but the other two are off a bit.20231023_1603072.thumb.jpg.bfa884119c1df9f6dce3aa25949b4682.jpg20231023_160632.thumb.jpg.90986a411a2aeb6171fbf1a5d2df642a.jpg20231023_1611582.thumb.jpg.7b3e7be36846b0fb8183e0c19eb8e58b.jpg20231023_1610252.thumb.jpg.904e699628200034732a804cb6a42280.jpg20231023_1615542.thumb.jpg.248298e2366735860aacc3ab9af8fbea.jpg20231023_1613222.thumb.jpg.98fdebdd60e6258ab82305b14e5de352.jpg

      Longines with 25.17 caliber

      How do the timegrapher readings look after the watch has been running for 24 hours? Are you using a phone app or a dedicated timegrapher to take your measurements? Best Regards, Mark

      Replacing crystal, do I need a bezel tool?

      By Kalanag · Posted

      From what I see, the crystal is made of mineral glass and is secured to the bezel with a sealing ring. If you might want to replace the crystal without removing the bezel or the movement, I think it's possible, but risky. You have to suck out the old crystal without breaking it into tiny particles. I would not do that. If you remove the movement first you can press the crystal out and press a new one in without removing the bezel.

      New hobbiest to watch repair from the Netherlands

      By Sebastiaan · Posted

      Hello Everyone, A short message to introduce myself. I'm Sebastiaan (50) from the Netherlands and have always been interested in watches. My two kids are at the end of their teens years and so I have more time to start a hobby.  Working on watches was something I always wanted to learn. So I recently started the watchfix repair course. Currently watching level 3. My short term goal is to be able to service the watches we (Myself, my wife and kids) own. I own a manual Omega Geneve from 1974, a small microbrand watch with a NH35 and a wittnauer bumper from 1940's. My wife owns an Oris, Seiko 5 with 7s26c and my son a seiko alpinist sarb017 and sports 5 with 4R36. So enough to learn on the short term..  Looking forward to talking to all of you and enjoying the watch hobby together. Greetings Sebastiaan

      Longines with 25.17 caliber

      It works quite well. The only strange thing is that it loses 2/3 mn per day whereas the measurements indicate that it is fast by 1/2 mn. Maybe something wrong with the gear mechanism ...

      Longines with 25.17 caliber

      By rehajm · Posted

      Unfortunate…but you clearly have a Longines branded movement with a year 1936 serial consistent with the caliber. I checked the case maker of the last few Longines I worked on… …same as your watch, so certainly you have grounds to honestly describe your watch as a Longines cal 25.17 tank with unbranded dial…and given the modesty of the watch IMO the Longines authentication wouldn’t dramatically alter the value, if that’s what you are hoping…as nucejoe suggests the value will mostly be determined by how well it runs…
