Hello :

I recently inherited this watch. I've spent a ton of time trying to find out about it without much success, since it seems like there are infinite numbers of Omega watch models and this one is very rare. So my last option is to recurr to some forums and hope someone helps me with some info. Thanks in advance to any replies.

As to now I've established the following information :

Omega Constellation 18K Yellow Gold Day Date with Gold Dial and leather strap
Estimated price from only 3 that I've found in the whole web $1.700-2.500

It seems the watch is very rare since I've found so few similar watches, and on the Omega site they currently don't sell any Constellation models with that same dial with the month and date hands. The original leather strap has been changed, but seems to be relatively inexpensive (like U$S 50).

There is something weird with this watch though, the back/casing is steel and on all the other similar ones I found, the back is gold too. On closer examination the back looks strangely worn out and scratched compared to the front which is nearly perfect - the gold could use a polish and that's about it. I suppose that the fact that the back and casing is steel decreases the value of the watch.

My questions :
1) Is there any more specific model name or model number for this watch?
2) Does that dial, which appears to be discontinued have any name? (ie diamond dial, etc.)
3) Should this watch have a gold back/casing? Or is it posible there is a model with gold dial and steel casing? (or for example if it was ever serviced they might have switched the dial onto a steel casing? - my dad was always quite a distracted person and I'm sure wouldn't have noticed if someone had done this)
4) Any other random info about the watch would be useful.
