I am looking to buy an Omega "PIE PAN" Constellation Cal 561 (rose gold+ steel), in a decent condition. Dial condition is 6/10. Movement 8/10. Everythting else looks great. Original strap + buckle. Seller is asking for 300 USD.
Now heres the catch , one thing I spotted is that the case back is without the beautiful 14K observatory medallion.
My question -
a) is it a good deal ?
b) does missing medallion decrease its desirability for a collector?
c) how less should I offer?
d) can i buy a replacement medal to "fix" the issue, where can I buy such a medal?
Thoughts / suggestions invited. Thank you!!!
