Strickly a Speedmaster Professional follower and I need some assistance on this Seamaster. Is it real? What's the reference number? What years of productions. Movement? Collectible value?

Thanks for any help

 

Quartz movement, possibly a 1441 with thermo-compensation, can be regulated to +/- 10 seconds per year.

 

Thanks for the info. I think I'll stick to the 321/861 movement watches.
