Hi guys! Does anyone know how to remove a broke stem from a watch crown! The stem piece is level with the back of the crown, so there’s nothing to grab hold of, cheers!

I had one success (and one failure) dissolving a broken stem out of a crown with Alum.

The successes was a stainless steel crown and a milder steel stem. A Tag Heuer 2000 Automatic - here with the solution at around 60ºC I could see small bubbles coming up from the stump of the stem and it took maybe 6 hours to disolve

I tried to repeat this with another watch and it did nothing.....  This was A Bulova Ambassador with what again looked like a stainless steel crown.

If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard.

Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem.

You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.

 

Depending on the Crown material and Stem material, you can try dissolving the stem.

What's the crown made off?

      Message board problem

      By Mark · Posted

      Looks like the kind of message that occurs when there are routing issues between your local network and the remote server the site is living on - there can sometimes be 20 or 30 hops and when there are issues some of those hops become unavailable temporarily for some people but for others where there is a different path being used the issues are not manifest. Another explanation, and this used to happen to me a lot with my ISP, is using the ISP DNS servers on your device or router sometimes is not as robust as changing to a public service such as 1.1.1.1 or similar. I was having a terrible time watching Youtube a while back - changed the DNS on my Apple TV to use 1.1.1.1 and problem solved. However, these issues tend to resolve themselves fairly quickly.

      As mentioned by the other members, it’s a dismantle job clean and inspect the solder joints. It’s an older generation using the paxolin pcb  not the glass fiber ones.

      Hi  in regard to your questions,   The springs should ideally removed from the barrel but to do this you need a mainspring winder that are quite expensive for a one off. Or you c a make your own see Google “ joes mainspring winder”. I have made two and they work well, you will also have to source some tube for the retainers. the gathering pallet cann be removed using levers ( mini crow bars) again I made my own no problem. the case can be glued using evostick wood glue but bind the case together to close the crack. When solid you can use wax sticks (used for furniture) melted and rubbed in to cover any blemish left. best to clean the case and then use bees wax to polish, a bit of elbow grease needed  do not clean the dial with anything other than warm water and a couple of drops of mild soap. Try on an inconspicuous part first. There is a product called MILIPUTTY in various colours on eBay that can be used on cracked enamel dials depending on how bad it is .
