I took the advice of members and decided to educate myself before asking silly questions or buying a watch I'll regret later on. I posted last week after acquiring The Moon Watch book by Omega and now thanks to Jens - @watchme who sold me his spare copy of the Moonwatch Only book - I've been able to do some excellent weekend reading! If everyone else on this forum is like Jens - @watchme I'm in good company, great guy and someone who I will keep in touch with. Thanks to the people of OF.
