I've used this technique from our host to print a "minute disc" for my jump hour watch: -
It‘s an Omega 166.0173. it’s just a regular crown, not screw down. Thanks, that’s what I was looking for! I already got a replacement stem on the way, looks like it’s only a matter of time until it snaps while winding. I‘ll service the movement so if there is any rust, I will see it. Don’t want the dust to make its way to the gear train. You mean just the washer or gasket and then washer on top? Because the original crown definitely has just a rubber gasket or the washer got lost over the years. I‘m not sure if the stem actually got extended at some point, looks like the rust just thinned out the material quite a bit. It’s going to be replaced anyway. Fingers crossed it will come loose without snapping. -
Typically any place where 9010 is used you will find epilam to keep it in place. Typically what I've seen the recommendation of 9010 on the balance and escape wheel because are considered fast moving. Although for instance Piguet With quite a few of their watches uses 9020 is the thin oil including the balance and escape wheel. Basically one oil one Greece and the escapement lubrication. -
What about the groups of tiny jumpers, where one or two pairs of pads are soldered together? Would this be a factory calibration measure, and if so, I suppose a tool like the subject of this thread would allow one to reverse engineer its logic? Hm, wait a minute - this PCB has a trimmer and the jumpers. Any idea what else they might be for? Doesn't my phone keep amazing time because it has to do GPS? Its own inaccuracy would be corrected probably at least once a minute, wouldn't it? -

Not this type really, It's not something I would attempt, I'm sure there are those that do and certainly did do it without a jeweling tool. Friction jewels do need to be positioned accurately and set to the correct depth required, which is why the jewelling tool is used and was created, amongst its other uses.
