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
Ridewatches are armament devices designed like stopwatches that are the power sources for Ridewatch-compatible Rider Systems. Once created, they infuse the previous Kamen Rider's powers along with their memories as well as the history of their monsters as well.

Ridewatch Creation

 * 1) Confirm that an Another Rider exists during the present day.
 * 2) Meet the Rider on which the Another Rider is based.
 * 3) The veteran Rider will return the Ridewatch to the user and ask them to protect their wishes.
 * 4) Return to the past and defeat the Another Rider.
 * 5) Give the veteran Rider(s) a blank Ridewatch, in which they will later manifest when the user returns to the present day to receive them in Step 3. This is the start of a time loop in which the veteran Riders lose their memories from this point on and will temporarily regain them as Sougo approaches them in 2018.
 * 6) *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.
 * 7) **In episode 5, it's revealed Ridewatches not just steal the history of Riders, but also their villains, effectively erasing all conflict from time and preventing a much more imminent bad future from forming.

Miridewatch Creation
The process of creating a Miridewatch is rather different compared to the regular Ridewatch, as they are based off past heroes. However the three Riders from the Future, Shinobi, Quiz, and Kikai do not exist in present day, and therefore it would be impossible to obtain a Ridewatch from them. There is however a solution:
 * 1) Confirm that an Another Rider exists during the present day. The Rider that the Another Rider is based on cannot have already existed and must be from the future.
 * 2) Immaturely defeat the Another Rider, and have a blank Miridewatch on hand.
 * 3) Have Another Woz use his book to create the Miridewatch based on the Another Rider that was just defeated.

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.

The Decade 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 Decade 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.
 * Progress Cylinders (プログレスシリンダー) - Two cylindrical units located between the Decade Ridewatch's 'face' and Ridewatch slot. It 'upgrades' an inserted Ridewatch's powers, allowing transition into that respective Ridewatch's Rider's upgrade or super form.
 * Ride Canceller (ライドキャンセラー) - A black button located at the far right end of the Decade Ridewatch. It is a sort of security device that forcibly ejects Ridewatches connected to the Decade Ridewatch. Also serves as a button to release Ridewatches voluntarily.
 * Pict Window (ピクトウィンドウ) - The main monitor that takes the form of Kamen Rider Decade's face. It can holographically display information such as time and Ridewatch icons.
 * Groove Bezel (グルーブベゼル) - The Decade Ridewatch's reinforced outer frame, complete with Kamen Rider Decade's signature 'face bars'. It reinforces the Ridewatch and protects it from shock.
 * Wide Outrigger Grip (ワイドアウトリガーグリップ) - The Decade Ridewatch's entire outer exterior. It's shape stabilises the Ziku Driver's loading operation by letting the fingers of the Rider (when held) act as a boom (moving arm).
 * F.F.T. Slot (F.F.T.スロット) - A slot to attach Ridewatches to upgrade the Decade Armor.

A Miridewatch consists of the following parts:
 * Miride On Starter (ミライドオンスターター) - The activation button located on the top. When pressed, the Miridwatch enters a standby state to prepare itself for insertion into the BeyonDriver.
 * Outrigger Grip (アウトリガーグリップ) - The exterior body. The shape stabilises loading operation into the BeyonDriver by letting the user's fingers grasp the Miridewatch in a comfortable manner.
 * Gate Activator (ゲートアクティベーター) - The cover/capability valve. When inserted into the BeyonDriver, the Gate Activator splits, releasing the Miridewatch's latent capabilities and allowing the BeyonDriver to read it's data.
 * Pict Window (ピクトウィンドウ) - The graphic printed on the Gate Activator. Tells the user what the data and capabilities within the Miridewatch is.
 * Send Projector (センドプロジェクター) - The screen inside the Miridewatch that lies concealed beneath the Gate Activator. When the Miridewatch is loaded into the BeyonDriver, the Send Projector transmits data into it via super high-speed optical signals.

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.
