Whats it worth (1970s Omega Constellation)

[JohnnyE]

I can only find a really tiny pic to share here - but I have the chance to buy a 1971 Omega Constellation - which is my birth year. Its an automatic chronometer with a black face and date. Just serviced with 2 years guarantee. Case and strap described as excellent condition.

I love Omegas but just cant justify buying a modern SM or the likes - so this one will scratch the itch while being the same age as me! The seller bought it new in 1971 and seems very genuine on chatting... He is also selling his wifes Omega from the same year. This one I'm looking at doesnt have any box or papers though.

What would you say its worth?


(apologies for the small pic - its all I could find)
