Hi Stefan,
I would be more than happy if you were to start a new thread on any of these watches and told us a little history with some photographs.
And I would be ecstatic if you started with the Seamaster Calendar!
I too am constantly impressed with how accurate and well the vintage Omegas from the 50’s and 60’s run. They certainly do not take a back seat to my ‘modern’ watches.
Regards
Andrew
