Ticwatch Pro Bluetooth Smart Watch, Dual-Layered Display, NFC Payment, Google Assistant, Android Wear, Compatible with iOS and Android (Pro 4G-AU)
Try as I might, I couldn't find why the watch has been classified with the AU prefix, because as far as my research has gone I don't believe it's esim is supported by Telstra but will give it a go when mine arrives.
Otherwise this watch is the same as the more expensive Pro 2020, but with 'swim ready' up to 1.5m depth and a sports band rather than hybrid leather (leather doesn't go too well with chlorine/salt water).
Bands are interchangeable with any of the 22mm bands out there.
Add both promotions at Amazon checkout and the total for the top of the line ticwatch and their previous gen ear buds comes down to under $370!
