So as you guys no my taste run the gambit provided its in a stainless case. As part of a "lot" this little guy showed up. I'm remiss I didn't snap more photos for the record but I just got carried away. A shout out to Luis Longbike for pointing me in the right direction as to what movement was in this. (Jeam Brun) Seems it was popular in GI watches made for Westclox during the Vietnam War and sold at R&R venues in Honk Kong. This particular watch isn't marked France only by design was it ID'd. I'm still not 100% on it being a 23D or 26D. One bit of research say that for a time, after they had up jeweled the movement to 21, they hadn't quite run out of 17 jewel dials and from time to time you'll find a 21j cased under a 17j marked dial. In my case the dial is properly marked. From what I see though the differences in jewel count is just caps being added?
This was ticking a bit when shaken but the hands/time could not be set...After removing the back; the movement looked pretty clean. Hands off and removing the dial I noticed the dial feet are located pretty far inside the circumference of the plate. After removing the dial is when I saw the oil/grease had hardened and had locked up the setting and hour wheel. A quick strip and into the US for cleaning. I had to let the plate sit in the US overnight with the guard still in place; as the two tiny screws holding it on were too tight, and I'd started to jazz the screw heads. Next day with a bit of patients off they came. Assembly was pretty straight forward, though the trains in a bit different configuration then most with the ?Third? wheel being on the opposite side of where its "normally" sits.
After casing and letting it set over night I was disappointed that it had stopped...Turns out the hands were fouling. A slight adjustment and it was ticking away happily. I had the timergraph out to see what was going on with another watch (7009) and I decided I'd toss the Cralisle on. I got some very straight lines (maybe some of my best). A bit of fiddling with the Balance cock and I'd say its good to go. I had to loctite the crown back on and may need to source a new stem as the threads are fairly rusted away. Another note is I have found this movement in Elgin (878) and Gruen (515ss) watches also with their own movement number added to the bridge.
I didn't find reference to what the P72 might mean? Possible a date code?
Another odd thing I have not come across before is that there were shims under the bridge?
This little guy was only beating at about 18,000 so pretty slow, so I think an amp of 230° +/-5° isn't too shabby.
