Recently, Nikon's new patent registered in Japan was exposed. Surprisingly, the patent seems to have nothing to do with cameras and lenses. From the picture, it is a patent for smart watches.

The patent figure shows that the watch adopts a round dial, is equipped with a crown and a number of prominent physical keys, and the strap is small, so the overall shape of the watch is strange. Previously, it was rumored that Nikon was developing wearable devices that could be connected to the SLR camera to achieve more convenient remote photo taking. This watch may be related to remote photo taking.
