There are other sources as well but the watches from them all are more expensive and not as secure.
In fact, my FM crazy hours was not offered by any of the local dealers.
You could argue it is not very accurate.
Still, all dealers offer fantasy watches and I do see a watch now and then I'd like to have, which is not carried in stock by the local dealers.
Sometimes, apart from seeing pictures, you do need additional information on the watch.
You need to rely on what the dealer says.
