Early 60's Elgin 10K Shockmaster. I suppose one of their attempts at water proofing a watch (see the crystal and gasket in the second picture). The question is how to get the crown off (Its wobbly when pulled out to the set position and I am certain it contains a gasket) so I can remove the movement? Dis-assemble the keyless works in place so I can grab the stem and unscrew the crown?? Thanks.
I have an old Waltham pocket watch movement which is missing the impulse pin (roller jewel). I have a limited number of actual jewels and since this is just a practice movement I thought I'd try to make one out of brass. I've seen this several times in old pieces--usually a very sloppy job. So I got some brass stock of the same diameter as the "D" in the roller table, filed it and burnished it to a high gloss. Then I took a small, very fine diamond file and filed it half flat to form the "D" I then polished the face using progressively finer sandpaper on a steel block. This works fine--so far! Problem is separation of the piece from the stock. Again I used a small cutting file to do this but it doesn't leave the end very pretty. So what I've done so far is to fit the good end into the roller table. I then plan to shellac it in place and see if I can very carefully adjust the length and clean up the end. Has anyone done this before? Any suggestions as to how best to do it?
This is my first watch repair project beyond battery replacement and bracelet adjustment. After buying 2 non running Ingersol Triumph pin pallet lever pocket watches I now realise that they are not the best to start with, however now that I have them in bits I'm going to continue. One watch was really a basket case, the other ran for a few seconds then stopped, I have stripped both, cleaned the good bits and reassembled one watch (several times) I have got it to wind and to run but when I try to adjust the hands the crown is jammed solid. To recap, the crown will wind the watch but not change the hands. This watch doesn't have a conventional cannon pinion, it has a rather flat pinion (see photo). Please excuse my terminology, everything seems to be a pinion.
So this little pinion (gear wheel) fits on the shaft (pinion?) of the centre wheel, I suspect that it is too tight, as I understand with a conventional cannon pinion there should be some friction to drive the hand but also enough slippage to allow adjustment of the time. I'm not sure with this watch what sort of fit the pinion should be, and I would like to ask for advise before I remove any material and make it too loose.
Best regards, Alan
Found a good thread on WUS - acidic comments by a certain anti-social character aside.
Note at some point "benzine", that is, petroleum ether, is written as "benzene", which is a typical mistake of English speakers.
I have two Helm watches and they are very well made. I passed on the Komodo due to it's size. (40MM is small for me.) I did ask Mark Helm if he had plans for a larger version. He has always been responsive to emails.
