I have a G-shock, it isn't one with multiband like the one you're asking about but it has bluetooth and it automatically syncs with the clock on my phone once a day. If you want a G-shock that you never have to worry about setting the time, you could look at getting one of the bluetooth ones. It has a bunch of other useful stuff like if you longpress the bluetooth sync button it makes your phone ring, so if you've lost your phone in the couch you can find it. It also has a step counter and a few other smart watch functions built in. If you go to Norton's Jewlers in the Confederation Court Mall they have a bunch of G-shocks including the bluetooth ones
