What determines the case back medallion style on a Conquest? This solid GoldPurchases made through these links may earn this site a commission from the eBay Partner Network one from c1959 has the blue stars whereas this similar vintage SSPurchases made through these links may earn this site a commission from the eBay Partner Network (from the ebay recommended thread) has the green fish. And what's a realistic price for the gold one?
You'll find the green fish on the stainless and gold capped models and the blue sky with stars on the gold versions. I will say $2-2.2k for the one you mentioned but wait for Dennis as he is more informed on pricing.
Bingo. There's nothing special about that particular model. It's a $1400 watch given the condition. If it had the date at 3 it might be $1600, and if it had a date at 12 it could break $2000. The asking price of the seller is crazy.
I think UK prices are probably a bit higher, so maybe £1K2 would be more realistic than his asking price.
