Facebook has been working on a new smartwatch for the past few months.
According to media reports, the Facebook smartwatch will have a detachable display with two built-in cameras for taking photos and videos to share on Facebook, Instagram, and WhatsApp.

The camera on the front of the watch display can be used for video calls, while the 1080p camera on the back can be used to take photos when the watch body is separated from the stainless steel frame. (Sina Technology)
