if you are new to running a lathe, use a 3 jaw, jacobs' and collets. most nubies are afrade of a 4 jaw because it takes much more time to get it "on center". with some experience, a 4 jaw can be put on center in15 seconds.
Go to YouTube, search video by " staying sane "
see his video Elgin 293 Disassembly
at 4.01 into video you can see levet at 6 o'clock at very bottom of
screen, it is in up, locked poistion. see linkage to keyless works.
Movement put in case this way time cannot be change by crown.
The rim lever is under the dial. The case has screw on front, body
with stem and crown, and screw on back. To change lever you must
remove movement from body. The movement. only will come out
the front and the movement. two screws that hold movement to
body are on rear of movement. Therefore, the front and back must be
removed, then take movement out of body. The inside body rim holds
lever in " locked " or " unlocked " position. A picture with case front
removed only shows the watch dial, the lever is under dial.
I guest this it the mystery, why would you make a watch that can be
put in case and the time cannot be set without removing movement
completely from case ?
I think you may be able to remove front, remove back, turn 2
movement holding screws 1/2 turn, tilt movement up just enough
to move rim lever then but back together.
I would take more pictures, but I had such a time with watch hands
I am not going to remove dial again.
I measured it out, but the measurements didn't line up with anything out of the Incabloc catalog. I took a step back, and assumed I was simply having a hard time getting a good measurement on such a small and flexible piece, and thought maybe I could approach it from the angle of seeing what would have come with whatever movement it was based on. Once I realized it was a Chinese original, I pretty much figured I was screwed. I placed my orders for everything else, and I guess it's just going back to the "art" bucket. My order from Switzerland finally made it to Queens, so hopefully I'll be moving on to movements worth buying parts for soon.
