Omega 1002 tear-down

I had a 1002 with a trashed balance, bought on ebay.
Very little info on this calibre on the 'net, so here for my education are the stages of stripping the movement.

Three screws release the date plate

Mind the date jumper spring -it'll go for a flyer.
Removing the wheels :
Hour wheel, minute wheel, date jumper lever, etc :


Wheels removed, keyless works left in-situ. Evident that the stem release has to be pushed in on egress and ingress.

Flip it over :
Rotor is released by removing a small silver coloured piece :
Back of rotor and fixing piece :
The balance cock and balance already removed as N/G..
Winder removed :
under-side :
Having 'let down' the main spring through the crown, the ratchet wheel removed. Small spring on clicker :
Bridge :
Centre, third, fourth and escape wheel.



winding bridge : small spring for clicker. There is a small spring on the main plate to keep the unidirectional wheel in position.

  1. Nice pictures. I recently serviced an 1002 calibre and found out, to my horror, that the upper incabloc spring is broken. The click, winding post and the middle winding gear have seen better days, as well. Would you mind passing your 1002 parts onto to me? I live in Switzerland.
