I saw this technique on you tube a while ago and decided to give it a try today. Old lume is certainly something you do not want to be breathing in, so the safest way is to remove it under water. All you require is an ultrasonic cleaner, a piece of pith wood and a couple of matchsticks.

Trim the matchsticks to fit the hole in the hand and delicately press them into the centre of the hands. I find the best way is to lay the hands on the pith wood face up and then press the matchsticks into the hands. Once you have done that, press the matchsticks into the pith wood as in the pictures below.

Now take the pith wood complete with hands and float in the top of the water in the ultrasonic tank. The lume on the hands will be facing downwards as in the following pictures.

Give the hands a blast for three minutes in the tank, and all the lume will be safely removed leaving spotlessly clean hands ready for the new lume. See below.

Very good tip Geo. Not for painted hands, but for chrome or gold plated hands this is just the job!

Good point Mark I should have added that, unless you want to remove the paint. ;)

One other thing, if you leave the hands mounted on the pith and secure the pith to the bench with Rodico, it keeps the hands very stable for applying the new lume. :)

Excellent mini how to Geo, I'll use it next time...even with some of the painted hand ones, I have Testors paint so that simplify retouching them...more like a re paint job! Will come out very neat! Can't wait to start!.

Another way to remove the old luminova that works most of the times, is to place the hands in a tiny container with acetone for ten  minutes or so.

Before doing that, just get yourself certain that the hand are not painted since acetone is so powerful in removing paint!

Exactly what i did for my little resto project Seiko 6309-523a. Smells nice too [emoji12]

Not sure how I'd handle the liquid in the aftermath if the lume was Radium based. Tricky stuff.

It makes good drain cleaner, kills 99% of household germs! :D

    • Hi folks, I'm doing some homework on getting a watchmaker's lathe, and it's clear I have a lot to learn. But I know one goal: I want to be able to fabricate wheels, which would require an indexing capability. I know how to use large lathes- like, giant metal lathes- but my experience is a few decades old now (but you never forget the smell of the metal cutting oil). So I'm looking to learn anew, and have a goal to get to a point where I can fabricate some basic watch parts. I also have no specific timeframe and want to do this right, so I'll be patient and learn what I need to before spending the money. I know I'm not going to get anything for a pittance, but I'm also not really able to put together the scratch for a $5-$10k lathe. What's out there for a hobbyist that can either handle some fabrication out of the box or can be relatively easily made to do so? Thanks!  
    • Hello and welcome to the WRT forum.   This usually points to broken balance pivot.  Though a watch in need of clean & lube can do the same. Easiest diag would be to  see if balance pivot doesn't stay in hole jewel of the setting, when you lift one side of balance rim with an oiler or gently with pair of tweezers. Another would be to detach balance complete from the cock and take a look at pivot under high maginfication.  Regs 
    • Ahhh, yes.  I hadn’t thought of that.  I’ve serviced quite a few of these and the first time I didn’t realise it was a ships strike pattern!  Ha ha, confused me totally until I realised.

    • Hi Mike, I did, thanks. Found this clip that was really helpful:   It says Seth Thomas but it's actually the same Hermle I've been working on. I'd had it working correctly all along but hadn't noticed that the lever with the sprung end stops the hammer a bit short of the bell on the second ding at the end of the half-past sequence. If only I'd put the bell on when testing, rather than just looking at the hammer, my ears would have told me it was working,  even if my eyes didn't!
