Service + Dial Restoration: Omega Constellation calibre 501

This great looking Constellation is Robert’s.

The dial is in pretty bad shape, as the wording has almost faded, and the surface itself is damaged.

As all Constellations, this one has the Geneva Observatory on the back.

This Constellation dates from around 1954-56 and has the calibre 501 movement.

The movement is in excellent condition considering its age. The copper plating is still complete.

Having taken apart and cleaned the movement, I put the parts away safely and send the dial off for restoration – as usual with David Bill & Sons.

Reassembly starts as usual with a new mainspring.

Then I put the balance jewels back in place.

Top plate put together and the balance is swinging.

Now I turn my attention to the bottom plate.

After having put together the movement, I fit a new original Omega buckle to the strap.

The dial has arrived, and I polish and fit the hands.

I managed to get hold of an original Omega crystal (you can always tell by the little Omega symbol in the middle of the crystal) and press it on.

Time to case the movement.

We’re back to a stunning looking Constellation – such a beautiful watch. And I don’t just say that because my Constellation is my favorite watch 😉

Just stunning…

  1. Hello Christian,

    Please can I have your permission to show picture IMG 5424. There is nothing wrong with the watch, it just that I have had an offer and they want to see a copy of the inside photo. I think its appropriate to ask you permission to copy the picture. Hope all is well with you Kind regards Robert.

  2. Dear Sir …. can you help me , how to polish Omega Constellation watch … ?

    what technique do you use ?

    as it seems very difficult to me ….

    • You are right, polishing a watch case is no simple feat. I wouldn’t attempt it without knowing what you are doing, as it’s very very easy to ruin the case. Also, I’m no great fan of polishing. It takes off material, and that is lost forever. Wear it with pride and scratches. You can’t unpolish a case 😉

  3. What can I say! It’s a credit to you and the dial restorers David Bill & Sons. This Constellation will stay in my family for another 50 years at least. Thank you Christian.

  4. Even by Constellation standards that one is a cracker 😉

    What are the scratches on the bottom plate – surely not service date marks?
