Very simple design to mount an FPV watch to a Taranis. Only requires an M3 bolt (~7mm long) for mounting. Simply remove the wrist band from the watch and re-attache the metal spring rods. The watch easily snaps in and out of the mount. You can still use the antenna on the watch.

Slide the mount on to the lanyard bracket. Insert the M3 bolt from the bottom hole (Closest to power switch) and thread in to the top hole.
