Even worse, my Casio can't even change the default mm-dd to my country's default dd-mm, keeps throwing me off.

I used to walk around with a Casio always, I would have welcomed this connectivity, but now I have a Pebble and I like the balance. Could have done without the HR monitor, and with GPS though (some features don't work without phone connection, too many I find). Other than that, perfect for me.
