      Dear friends,   This small centenary pocket watch of my collection came to me without a crown as you can see.      This is a pity, since the mainspring and balance test as working and everything else seems to be in good condition.     The stem sits correctly inside the sleeve and can be adjusted to two positions (winding/time setting).    
      I have taken some measurements in case any one has a spare crown of the correct size:
      Crown (base): 4.6 mm.
      Sleeve (outer diameter): 3.36 mm.
      Stem (length): 9.44 mm.
      Thread (length): 1.72 mm.
      Thread (width): 1.14 mm.
      Square end: 0.99 mm.
      This grandpa-watch really misses its old ticking days! 
      Please have a look in your spares. Thank you in advance!

      I seem to have developed an affinity for pocket watches and I found this video by Fran Blanche, she has some really interesting electronics tear downs and articles, if you're into that sort of thing, and now I find she's into pocket watches.
      I think its the embellishment on the insides of the pocket watch that catch my eye.
      Nothing in depth, beginners level, which is probably why I like it.

    • First, I recommend the right movement holder. The ETA 775X has been covered a lot on these pages and you can find good videos on the subject on youtube. Sent from my iPhone using Tapatalk
    • The auto system on this caliber is very simple. The reverser is really just a pinion on the rotor which is held in one direction by a click spring. The pinion needs to turn freely (minus the spring) on the rotor, and be lubricated. When hand winding the pinion spins past the click; if the lubrication has become sticky the rotor will spin. Use a plastic pointed stick (or two) to remove the clip holding the rotor on, it's very easy to scratch the rotor with metal tools.   If you do a full service on it, beware of using alcohol on the date support (it's a full plate made of acrylic that covers the dial side)- alcohol will damage it. It's possible that the latest executions changed the plastic but I don't think so. I wouldn't recommend it as a first chronograph, it's a robust movement but has some tricky parts to deal with.   Here's a manual
    • Clean and check winder module, treat with epilame fixdrop, be prepaired to replace the reverser with new. Good luck
    • A techsheet helps and thanks to watchweasol will be furnished, If the caliber is made known,  otherwise taking pix as you disassemble is helpful. No shortage of help and advice here. Good luck
