I bought this watch in July 2017 at quite a cost as it had to be shipped out from the USA with the extra VAT and duty payable on arrival in South Africa. So 19 months later the band is seen splitting. The band contains the Wifi, Bluetooth and LTE antennas and there are not even easy to obtain replacements without the antennas. One place in Korea sells them at $70 each. The lesson is don't buy devices that do not have easily replaceable bands or batteries!
