This is the only Omega I own. I think it is simply an Omega Automatic, but it looks a lot like a De Ville. This watch is from about 1975 and was a gift to my grandfather, it is inscribed with a date on the back. I later inherited the watch without a band and bought a leather band for it.
He wore the watch all the time and it certainly looks well used. The glass (sapphire?) is scratched and chipped. The metal case is also well worn with some dents, dings, and scratches. It looks as if someone at some point had tried to open the back up without the correct tools. As I said the watch was given to me without a band. I assume that the original one broke or was too far gone to save.
My grandfather died in 1991, so he wore the watch for only about 15 years. It spent the next 13 years sitting in a jewelry box until my grandmother died in 2004. I was never set to receive the watch, but when my mother found the watch among my grandmother's junk, she said that I could have the watch.
It looses about an hour a day unless I've been wearing it for several days on my other wrist, then it seems to be as accurate as my '99 Swatch Irony Aluminum.
Is a long wind-up to full accuracy normal for automatic mechanical watches?
If anyone knows anything about my Omega, I'd be pleased to hear it.
