Longiness La Grande Classique movement removal


Recommended Posts

Hi!

Struggling with movement removal in Longiness La Grande Classique. Photo tells everything:

To remove movement I need to remove hands and dial only comes out front side - i.e. need to remove crystal without removal of movement.

Removed crown, and tried with syringe and o-ring but no luck - getting pressure leaks from place when syringe contacts with o-ring/watch before crystal pops (even though I feel significant pressure on syringe). Any ideas?

Ok managed to apply enough  pressure:

 - 3d printed adapter

 - o-ring

 - BTWIN 900 bicycle pump

 - one person holding watch and adapter another pumping the pump

 - used watchmaker pad to protect the crystal (i.e. put watch on it crystal down)

    • I don't understand why did You use the bubble wrap. If You thing there is any use to hold the thing exactly in the middle of the hole - wrong, there is no matter, just pass it tru the hole and take it away to at least 40 cm before release of the button. If You reduce the current, then You reduce the field strenght too, thus not alowing the tool to be demagnetised if it is holding stronger field than the coil can create. My advice is to eat You breakfast (for more muscle strenght) and to fix the demagnetiser to the table or bench top with some clamp so You will be able to use the both hands, then ask You wife to press the button for You...
    • In WW2 they used to demag submarines. 
    • You know when you pass pieces through the hole, how far do you continue to move them away from the demag ?   With the blue china ones if i don't move the steel far enough away it doesn't fully demag it , i also carry out the process twice. For a tenner its working perfectly for me up to now. Thats a big jobby Jon, even though the blue effort is working fine for me this will look well cool sat in the corner of the watchroom and might pull a few lost parts from their hidding places as a bonus . Flick the switch with a bargepole from the doorway to avoid a zinging barrel arbor taking an eyeball out.
    • Yup, I have one of those up in my shed and it's extremely effective. I picked mine up at a car boot sale for a couple of quid because nobody knew what it was. Mine looks like it came out of the Ark so I guess that they've been around for a long time. Generally for watch stuff I use an equally ancient pass through type which is usually sufficient but for really stubborn items, particularly tools I use the Eclipse.
    • I would doubt the part is available, you'll probably have to make your own.
