I've an ecclectic collection with some vintage beauties from Heuer and Omega.
I've just picked up this Hamilton Chrono with Lemania 1873 from ebay, but dont know much more than that this caliber is family of the Omega 861, a simplified 321, produced from 1968 onwards.
Can anyone here help me ID it?
I'd appreciate links to documentation and/or resident guru's?
Thanks, Jurgen, Amsterdam
