Here is New Google Patent Pixel Watch… Resource Patently Apple has published a new registered patent of smart watches from Google – Pixel Watch.
The images demonstrate the attachment structure of the interchangeable strap to the device itself. Change the strap will be easy and fast. Special magnets (number 409 in the diagram) will make sure that the bracelet does not suddenly come unfastened, and the device does not fall from the hand.
Perhaps the company plans to release a large collection of straps in different styles, as implemented for the Apple Watch.
Google has been registering such patents since 2016. Earlier it was assumed that Pixel Watch will come out with a Google Pixel 3 smartphone in 2018, but WearOS Development Director denied this information.
