Omega Constellation Calendar Cal. 504 - Seeking Case Back & Advice

Looks like it has been through a fire and is heat/smoke damaged

I trust that you’re all doing well. I’m reaching out for a bit of guidance regarding my latest acquisition, an Omega Constellation Calendar Cal. 504. The piece is in rough shape, missing both its crown and case back.

My watchmaker has inspected the movement and confirmed that it’s in good enough condition to be serviced. I’ve managed to source a period-correct crown, but locating an appropriate case back (which I believe to be ref. 2943, based on my research) has proven quite difficult.

The dial shows its age and wear rather honestly, and I intend to leave it untouched. My goal is to bring this historically significant timepiece back to life as faithfully as possible.

I’ll attach a few photos for reference. Any leads on a case back, or general insights from those who have tackled similar restorations, would be deeply appreciated.

Many thanks in advance for your time and expertise.

Kind regards,

Yes, finding a case-back could require patient hunting. Given the overall condition, it's not something I would pursue, but if you're interested in restoring it, then best of luck. I'm not sure what specific question you are asking.

Wow. Did not expect that. What a unique and interesting look.

Fire damage could be the new tropical!

Great outcome considering what you started with.

I honestly like the dial (even in the 1st pictures), I think it turned out great! The clear case back is neat as well.

Wow, that dial looks amazing considering what it originally looked like. Mind if I ask how much this restoration cost? (And how did your watchmaker clean up that dial?!)
