Took a wild punt on this rather sad W10 This is the ebay pic :
As you can see (and as described) no crown and some damage to the dial.
None original crystal, loose in the case, and no tension ring.
Hands are good, but dial has missing paint on face and lume on RHS is water damaged.
Movement keeps good time (once I'd found a suitable stem).
Case not too bad.
dial off and back of movement
hour wheel off.
Cannon pinion was very easy to remove. Too easy?
Keyless works.
mind the spring!
Just visible - end of the hacking lever?
Front side of movement.
Wound-down and balance cock and balance removed.
Balance complete.
Spring! for clicker.
Power chain bridge off - hacking lever visible.
2nd (not centre!), 3rd, 4th wheel and escapement.
bare.
Overall, movement is in good condition and will just be cleaned and oiled.
Split stem
So this is a one piece case, and requires a split stem, which I've not done before.
Movement is a re-badged ETA 2750.
I emailed, looking to get a male stem and female extension. Naturally I ordered the wrong bits, but received a very informative email from John :
Hi,
Non of the crowns will be of use for the Ham w10, you dont ask for the stem that fits into the movement, this has a male end, I have these @ £5 & if you use the female crown necks you are nearly there, the hard part is obtaing a crown, ham used a longer than normal 3.2mm deep crown with a diam of 4.9 any larger & it will not fit into the recess, thread .9 to fit over a tube 2.5mm. cousins uk do a divers crown which will fit I cant recall the order code but it is under their divers double O ring section.
john
I also ordered the suggested divers crown from cousins - 4.5mm (bit too small), but fits the tube well.
