Hey guys, so I found someone selling this Speedmaster. How much should I pay for this? And is it considered a collectible?

Thanks for the help!

 

Looks like a Speedie from the 80's (movement number and dial) with a caseback (105.012-66CB) and bezel from the 60's (DON). Definitely NOT collectable. Definitely IS avoidable.

 

That is a strange concoction.

At the very best, if you were willing to be extremely optimistic, you might cross your fingers and think it's a 60's watch that was sent to Omega in the 80's for a service and received a new movement and dial.

Unfortunately it's probably just a complete Franken.

 

This forum has saved me from 2 potentially regrettable purchases. Thank you all!

 

The 48m serial makes me wonder.

There was a time when entire movements were changed at service. Could this be an Omega built one? All the movement swaps I have seen have been 48m serials.

I have never seen it in a 321 case before.

Just to be clear, @Gemini4 's and @Davidt3449 's advice is spot on, this isn't worth more than a parts sum.

Just interesting to an anorak like me.
