  1. those rusty screws will not snap off with aplication of proper penitration oil. vin
  2. any wrist watch with a battery, can not be a trench or vintage military watch. no mater what e bay says. they look nice, may run well, but not worth anything. vin
  3. is not murc. poisonus ? replace it with fake weight, right side up. vin
  4. miniture screw drivers can be nicely "by eye". it is not "an art", but the result of a machinest's apprentiship. twist drills can aso sharpened "by eye". i will admit the small ones can be dificult ---- practice. vin
  5. the ring is part of the case, holding mvt. in. the proper crystol fits over it. vin
  6. about the twentys, between the wars, a lot of stuff was not marked while gearing for the next war. vin
  7. basic math if you remember. the stem cutting and thread shaping requires some thought. i do not glue crown to stem, just set it "tight". vin
  8. welcome. you have chosen a good book for a start. good for reference and basic use of tools and a good forum to help you. vin
  9. removing rust is always a sad project. that watch was was very collectable at one time, kind of a cheepy. sell the mini and and the watch? vin
  10. buying attachments for a lathe - be careful. an example; the head stock (what you screw the chucks onto,) on an U S lathe is 1/2 x 20 thread. tooling made for a metric head stock WILL NOT FIT ! vin
  11. it may be epoxy. if you can get the mvt. out of the case thru the front and deal with the case later. if it is epoxy, use a jewelers saw and cut the crystal at the edge. vin
  12. thread pitches; S.A.E. or MM ? vin
  13. some watches are designed to only fit factory watches. i like to use generic plastic crystals. my original batch of boxed diameter, were made in India. they seem to have gone out of busines. they could be turned on the lathe to fit the lip. vin
  14. some of those snap backs have a thin seal ring, hardly an o ring, generly fall apart. vin
