What to do about worn Timex crowns

Having gotten my Timex model 27 up and running, I've got another hitch both with this watch and two others that were straightforward clean/oil jobs:

The crowns have been worn almost smooth and unfortunately Timex crowns do not appear to be screwed onto the stems. I'm not sure how they were fitted to the stems and Google is not particularly helpful when it comes to removing and replacing them.

I've kicked around the idea of using either a needle file or a blade to cut new grooves, as this would keep me from having to make sure that the stem still seats properly with a replacement crown, but I'm not overly fond of this approach either.

NOS stems and donor watches are getting increasingly harder to find. 

I've been toying with the idea of removing the old crown and cutting threads on the stem to fit an OEM crown.

One day I'll get down to doing it.

Right now I have an Accutron crown that sticks out by a little more that a millimeter. Obviously it doesn't belong to this case. And it's also a pressed on crown. Hmmm... 😏

Unfortunately, Timex crowns are press fit onto the stems, so there's really no way of cleanly removing and replacing them. I've toyed with the idea of pulling it off, milling out a regular crown and pressing a new one on, but i choose to just buy used Timexes with good crowns to service.

You can find NOS boxes of stems and crowns on eBay, but you have to find the exact one you need, and you need the service manual to find which one you need. I'm sure someone here has the manual in order to help you out.

      Black coating on shock jewel metal housing

      By Neverenoughwatches · Posted

      I use elma ammoniated H , the jar remains open for around five minutes while i set the basket up clean and spin off the cleaner. The smell doesn't bother me at all, i do this in a 10 by 8  foot room, but i think I'm immune to most environments 🤷‍♂️. I could open a window or a door i guess but watch repair under the influence of toxic fume inhalation adds to the overall experience. ( just joking peeps dont try this at home ).

      Bezel replacement difficulty

      By Simeon · Posted

      The bezel feels slightly loose over the case. There wasn't a gasket but could the crystal be expanded over the lip in the caseback and then the bezel pressed over the crystal?  Actually this sounds like a possibility. This is a great forum. https://www.watchrepairtalk.com/topic/20587-old-orient-case/?do=findComment&comment=173918

      The cleaner smells of ammonia, but it's not too bad; just keep it covered as far as practical.  I use an ultrasonic machine on a kitchen worktop. The rinse does not smell strongly, it's vaguely like paraffin. I did check the safety data sheets before buying it & it's said to be safe in normal use. My dedicated watch cleaning machine is still a work-in-progress; four position linear, based on 1L kilner jars for station spacing, to have a heated dryer in position 4. It uses standard, readily available parts as far as possible to make it easy to reproduce, plus 3D printed bits for the custom parts. (The horizontal drive motor is out at the moment while working on the stepper drive software)

      Citizen Pilot Radio Controlled hour's hand clearance

      By Albyon · Posted

      I disassembled the hands of my Citizen Pilot Super Titanium Radio Controlled AS2031-57E a couple of times.  The second time because on the first attempt i evidently did not push the hour hand well and in practice it was not well fixed and moved receiving even small bumps. After the second attempt everything seems to be ok.  Except that i have the impression that giving a little more sustained blows on the wrist, the hour hand still has a slight movement, in the order of half a second or less. It is a normal, topical and usual thing about this movement, which, i remind you, is exclusively electronically managed, each hand independently, a clearance in the movement that it has of its nature, or it may depend on the hand is not yet well attached to the pin and should perhaps be replaced because the hole has slightly enlarged?

      Balance staff sourcing?

      By Neverenoughwatches · Posted

      This is something a lot of beginners and amateurs struggle with Nev, being able to remove the staff without distorting the hole of a non steel balance wheel. Having the right tools to do this safely  and effectively is not easy. Even with something useful it takes a lot of practice, i spent two days not so long ago practicing cutting away the balance wheel hub of a staff using a 25mm diamond wheel.  I didnt manage to do it once without catching the underside of the wheel.
