Re: Speedmaster Professional Chronometer...Real?
Hi, there have been indeed some (very rare) Speedy Pro's "chronometer", in that they were fitted with a chronometre-certified version of the 1861 movement.
If I remember right from Omega's own "The Moonwatch Book" one batch was produced as a limited edition to celebrate a specific company celebration, though I can't remember which one.
Most of these were in precious metal such as platinum or red gold, and just a few ones in steel. Expect all of them to be quite valuable.
I wish I had such friends as these giving away such gifts ;-)...
Cheers.
