Oh, I usually do mine on Ebay, but you have to be careful. Many Ebay sellers are totally innacurate regarding the crystal composition.
Also there is a good place named bluedial.com. You won't find too many sapphire models in the US though.
A foreign guy who can be trusted is the sky Watch guy http://www.skywatchdealers.com/watches/index.php
You won't get the warranty on the foreign ones though, ONLY the US models sold through an AUTHORIZED dealer. I believe Bluedial is auth and you will get the 5 year S warranty. Citizen has a good warranty and they are the best regarding warranty service, in my experience.
