Wow, that is a beautiful watch!
Wow! Two years ago I went to the Omega offices in Mexico to have two of my watches (f300hz) serviced and they rejected me because they no longer repair these calibers, not even in Switzerland.
Wow! I never heard of a D-shaped Constellation before and that's the first example I've ever seen.
Thought my eyes were playing tricks on me when I first cast my eyes on your photos.
Good ol' WRUW! Always an education.
I went to the local Omega Boutique in Orlando and they shipped it to Switzerland. They told me it would take from 8 months to a year to get it serviced.
