Repair + Service: Omega Geneve calibre 1012

This Geneve belongs to Neil. The second hand is missing, and it needs a service.

I get very lucky, and Cousins actually have the original Omega hand that’s missing!

The 1012 looks very similar to the 1020, with only minor differences.

The dial could be in better condition, but it’s not bad considering the age of the watch.

The bottom plate.

The wheel train. The little white plastic on the left is to stop the balance when the crown is pulled out fully for the hacking second feature. Odd that somebody felt compelled to scribble on the auto-winder bridge…

All parts ready for the cleaning machine.

A new mainspring goes in.

The movement comes back together.

Top plate together and balance swinging.

The setting mechanism on the bottom plate.

The new second hand looks pretty good!

Now I can case the movement.

There was no gasket in the case back, and I put in a new one.

Back to its old glory.

Neil sent a new bracelet to fit, as the current one is too short for him. Looking good!

  1. Beautiful! I have a calibre 1012 omega as well and i’m looking to remove the movement and dial ( seconds hand has fallen off ๐Ÿ™ ), however i’m an utter amateur to the watch scene, and i’ve removed the caseback, but i’m having trouble removing the movement and dial, could you provide some jnsight jnto how you remove the 1012 movement and dial? Much appreciated! Nice watch btw ๐Ÿ™‚

    • Morgan,

      Shouldn’t you practise this with a cheap watch? This won’t end well, and my suggestion is to close the case back, and to give the watch to someone who knows what they are doing.

      Best regards,

      Christian

  2. The Geneva hasnโ€™t worked for 25 years. It will be great to see it fully restored.
    I will also need a crystal and a new strap. Any info on where to obtain would be great. When Iโ€™m done Iโ€™ll post a vid so you can see what your tutoring has achieved. Cheers

  3. Hi Neil
    Thanks for the 1012 tear down rebuild. Brill. Iโ€™ve copied to a T to clean up a Geneva cal. Now Iโ€™m ready to reassemble. Only think is the escape wheel is missing. Do you know where I can obtain an escape wheel?

  4. Hi

    Hi, Im looking to replace the dial on my cal 1012 and am just wondering if other cal. dials would be compatible. If so which in particular? thanks for your advice.

  5. Hello. As an engineer I found this procedure very interesting but would not attempt a service on my 1012 which I purchased new in 1978. and have to find a place to do it as it stops once a day at a non specified time in the night, it keeps good time, but the date change does not work.
    What i really want to know is, on the procedure of yours I watched, at what stage do you lubricate the movement and how, do you have an oil mixed with an agent which flashes off to give a v thin coat everywhere?
    thank you.

  6. Hi, Christian, I just purchased a very clean watch with this movement. Do you know when Omega started using it? Really enjoy your Youtube vids!

    Thx

    • Hi Lauren,

      Check the serial number of your movement, and then compare it to a list of serial numbers to years of manufacture – just google for “Omega serial number year”.

  7. Hello Christian,
    Can I ask you if I can use the First picture of your post (front face Omega 1012) because I just serviced one but I dont have a correct picture of the watch…
    I have the pictures of the work ๐Ÿ™‚
    Regards,
    ร‰ric.

  8. Hello,

    Nice job !
    I just serviced the same Omega 1012 and I have a couple of questions :
    – is this calibre 1012 manual winding (in complement of automatic winding) ?
    – Have you a picture of the wheels that are normally on the stem (pignon de remontoir et pignon coulant) ?

    Many thx for your reply !
    Eric.
