A new Apple patent has solved this problem well. The patent shows that when we take off the watch from one hand and put another watch on it, the news from the first watch will be transmitted to the second watch. And the second watch will synchronize the data of the first watch.
The patent solves the problem of synchronization of data between two watches and connection with a mobile phone device to receive messages when frequently changing smart watches.
At present, the patent has already been applied for. It may be applied to the next generation of Apple Watch. Does this feature prompt you to buy two Apple Watch?
