Hi there and welcome
There are a large amount of books on the subject, many of which are expensive and/or difficult to get a hold of. I would recommend you to start read the entire Omegaforum.net back catalogue of threads - this is one of the best ressources online and it is free. If you care for vintage Omega Constellations, you should go have a look at
Desmond's Blog or if Speedmasters are your thing look up
www.Speedmaster101.com
I have gone through the Vintage Omega subforum twice and I always learn new things - or re-learn something I've forgotten.
