These Thai made fakes are a little different to the Chinese who can fake anything with impunity. By stamping a non-existent number on the case back, they think cannot be pursued locally for counterfeiting as the watch does not purport to be a specific model. But they can be had for infringement of the gold regulations and of course copyright law, such as it is in Thailand.
But, I like Steve's explanation better
