Pete, if you are in Melbourne go and see the boke at the antique watch shop in High St and talk to him. From memory his name is Romi. Then, before buying anything get him or someone of similar standing to check it out.
Also, make sure you get a 100% money back guarantee and try it for a week. If it is not keeping time you don't want to pay for repairs.
I bought two fake ones in Thailand a few years back. Took me awhile to find the quality as there are fakes and there are fakes. We put the Daytona up against a real one and could only tell the difference because of the band. Everyone in the room was shocked.
