Hello, just looking for a little bit of advice.
I have an old watch that I have purchased, I would like to repair a problem it has with the stem not staying in.
It has tritium hands and hour markers that are approximately 30 years old, would it be safe to remove the hands to replace the movement?

Tritium is safe, especially that old. Radium, even if not glowing anymore, is not safe, and you should be careful.

A friend of mine did a watch where the radium paint shattered out of the hands when he took them off; he got a Geiger counter a few weeks later and it was still getting readings on his his bench.

I concur with Nickelsilver.

Ocean water contains tritium where healthy marine life goes on. We get a dose with every fish in the dish.  No worries, safe.

Thank you Nucejoe, so pleased that it's safe to operate on. Thought it best to ask before attempting, it's a old Avro military watch so best be careful with it. :)

    • Thank you for your input. I hope to be able to have a look at this again at weekend and will report back as soon as I have an update. It should be easy to see what's happening if I wind the mainspring with a screwdriver while watching the timegrapher. I do strongy expect that there is not enough slippage due to lack of the correct grease or a rough barrel wall.
    • Ah, it works! I split the first piece of text into two (thought it was a single URL).    I see a pin pallet movement. Not sure immediately what it is, but may be worth looking up EB and BFG. 
    • For light duty, the Chinese made stainless steel models are ok. But they do not last for ever. Make sure you use a basket which suspends the mass from the base as this interferes with how the bath resonates. 
    • Ultrasonics are a bit of a no-no for earlier work, especially where brass has been work-hardened as it creates microscopic fractures which deteriorate when treated to ultrasonics. By “early”, I’m taking Victorian and earlier, and mainly plates.  However, they are still very useful for some parts - I used an Elma ultrasonic for cleaning some fusee cones and steel chains earlier. I used Horolene which is very powerful for the brass cones, and L&R watch cleaner for the chains as it is oil-based an so would not subject them to water where possible. 
    • Same again... I ”think” l’m doing it the same way as I have always done. Have you tried the links? Sent from my iPad using Tapatalk
