Came across this deal when looking at Samsung's 4 Day Sale on Wearables and Tablets... Personal Digital beats their price of $509 with their $499.95 offer. Sells for $594 at Harvey Norman and $599 at JB HiFi.
It's Australian stock with a 2 year warranty.
I actually bought this watch about a month ago, pretty stylish and perfect if you have the Galaxy S6 or 7... So far everything is great - nice screen, plenty of functions, good battery life, etc.
