Ridewatches

The Ridewatches (ライドウォッチ) are pocketwatch-like devices that contain the power of past Kamen Riders, used by the Riders in Kamen Rider Zi-O.

Overview
to be announced

Functionality
Once a Ridewatch is selected, the Rider will turn the face of the watch 90 degrees away from the button on top of the Ridewatch so the arrow faces the Driver. The button is then pressed and then Kamen Riders Zi-O and Geiz insert their personal Ridewatches into the right-hand side of the Ziku-Driver and rotate the Driver 360 degrees counter-clockwise to transform. Ridewatches based on past Kamen Riders are inserted into the left-hand side of the Ziku-Driver to access Armor forms based on those Kamen Riders.
