I have upgraded to a gear s3 smartwatch and have no need for these anymore.
1) Gear 2 Neo, 4gb ram, can be used as a fitness tracker and you can also play Dick Tracy as you can take and make calls (with connected smartphone) say when you smartphone is charging or if you dont want to get it out of your pocket. Can connect standalone to bluetooth headphone for music. Comes with wireless charging dock.
$70 plus p/h or pickup in Glebe
2) Gear S2 Sport. 4gb ram, a much classier watch style smartwatch. Fitness tracker, heart rate monitor, music player etc. Can send sms from your wrist and many apps are available. Comes with wireless charging dock.
