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

Design
A normal Ridewatch consists of the following parts:
 * Ride On Starter (ライドオンスターター) - The activation button on top of the Ridewatch. Turning it on will shift the Ridewatch to a standby state before inserting it into the Ziku Driver. Pressing it again will allow the Rider to execute a finisher.


 * Outrigger Grip (アウトリガーグリップ) - The overall exterior body of the Ridewatch. The shape stabilizes the rotation motion of the Wake Bezel and loading of Ridewatch into the Ziku Driver.


 * Wake Bezel (ウェイクベゼル) - The dial of the Ridewatch. It is an energy release valve. By rotating it from its sleep state, which displays the Rider symbol and corresponding year date (in A.D.), to its active state, the Ridewatch becomes active, which displays the full face of the Rider.

Functionality
The Wake Bezel is turned 90 degrees clockwise, causing its arrow to face the direction that it is inserted into the respective slot on the Ziku-Driver. It activates when the Ride On Starter is pressed, and it is inserted into its corresponding slot on the Ziku-Driver before it was rotated 360 degrees to transform. Zi-O and Geiz 's personal Ridewatches are inserted into the D '9 Slot to access their base forms, and Ridewatches based on past Kamen Riders are inserted to the D '3 Slot to access Rider Armor forms based on those Kamen Riders.

Creation
Like the second episode Best Match 2017, Sougo depicted the conditions to create Ridewatches:
 * 1) Meet the old Kamen Rider(s) from the present after either Sougo or Geiz meets them in the past.
 * 2) The user must say to them that he greeted them before, causing a Ridewatch manifest on the Rider's hands and the Rider will remember.
 * 3) The Rider(s) will present the user their complete Ridewatch and having a wish to protect it.
 * 4) Sougo gives the Rider(s) in the past a blank Ridewatch, which he will receive from them in the future.
 * 5) According to Woz's opening narration in episode 2, the Ridewatches actually "steal" the powers of past Riders along with their entire existence as Riders from time. This presents a sinister aspect to their creation, as Riders lose their memories and powers upon Zi-O or Geiz's first activation of the respective RideArmor.

Unused Ridewatches
The DX Ziku-Driver toy can be hacked via pin combinations to reveal the names of possible Ridewatches with no confirmation on their appearance in the show, listed as follows:

Interestingly, Zeronos, Meteor, Mach, Chaser, Specter and Build RabbitTank Sparkling's Ridewatch are absent in the toy Ziku-Driver's memory for unknown reasons.

Portrayal
The Ridewatches are voiced by Rikiya Koyama (小山 力也), who previously voiced Paradox Roidmude in Kamen Rider Drive: Surprise Future, Kamen Rider Bujin Gaim in Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle and physically portrayed Joe the Haze in Kamen Rider Black RX. He also voiced other equipment in Kamen Rider Zi-O, and Oma Zi-O himself.
