Ridewatches

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

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 in present day 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 bootstrap paradox 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) **It is us unknown whether the Ridewatches just steal the history of Riders, or include in that their villains as well, due to the villains in most Kamen Rider series having origins independent of that of the Kamen Rider who eventually faces them. While doing so would effectively erase all conflict from time and preventing a much more imminent bad future from forming by said villain faction not existing, The events presented in Kamen Rider Zi-O are in wild conflict over whether those part of a series villain faction or are the progenitors of their antagonism still exist in the setting after its timeline has been altered due to the creation of a Ridewatch or Anotherwatch. This Contradiction is seen most directly in episodes 5 and 6, with the respective villain factions appearing to no longer be active, but evidence of their prior existence and impact still being seen in the altered present.

Miridewatch Creation
The process of creating a Miridewatch is rather different compared to the regular Ridewatch, as they are based on past heroes. However the four Riders from the Future, Shinobi, Quiz, Kikai, and Ginga do not exist in the present day, and therefore it would be impossible to physically obtain a Ridewatch from them. There are two ways to do this:

Method 1
This method is used if the Future Rider has either not been brought to the present day, or if the Future Rider has become the Another Rider.
 * 1) Confirm that an Another Rider exists during the present day. The Rider that the Another Rider is based on cannot have already existed at this point in time and must be from the future.
 * 2) Immaturely defeat the Another Rider, and have a blank Miridewatch on hand.
 * 3) Have White Woz use his book to create the Miridewatch based on the Another Rider that was just defeated. This step can be skipped if White Woz is close enough to the Another Rider to siphon its powers from.

Method 2
This method is used if the Future Rider has been brought to the present day.
 * 1) Confirm that an Another Rider exists during the present day. The Rider that the Another Rider is based on cannot have already existed at this point in time and must be from the future.
 * 2) Bring the corresponding Rider from a point in time before their powers were stolen to the present day, and have a blank Miridewatch on hand.
 * 3) Have White Woz place the blank Miridewatch on the original Rider, which will steal the original Rider's powers and turn the blank watch into a fully functioning Miridewatch.

Method 3
This method is exclusively for Kikai, as the Rider nature is unknown to everyone, except Sougo.
 * 1) Confirm that Another Kikai exists during the present day. The Rider that the Another Rider is based on cannot have already existed at this point in time and must be from the future.
 * 2) Have Ora temporarily stop time to access a Holographic Keyboard from Another Kikai’s chest-plate.
 * 3) Have a Blank Miridewatch ready and have Geiz type the password ("Will Be The King") on the Holographic Keyboard.

Alternate/Erased Timeline Prevention
Since the creation of a Ridewatch involves going back in time, Kamen Rider powers from alternate or erased timelines/continuities cannot be accessed to create Ridewatches as seen with Another Ryuga, whose powers are derived from an erased/alternate continuity. As such, neither Zi-O, Geiz, or Woz can travel back in time to start the process of creating its respective Ridewatch as the timeline the power is from, technically doesn't exist, meaning that Another Ryuga is invincible using conventional means. This is the same case with Kamen Rider Ryuki, although Oma Zi-O is in possession of the Ryuki Ridewatch, meaning there is a possible way of bypassing this prevention. Also because the Time Jackers were able to infuse Kamen Rider Ryuga's powers into an Another Ridewatch, they too seem to have a way to bypass this alternate timeline restriction as well.

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. Its shape stabilizes 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 Miridewatch 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 stabilizes 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 graphics printed on the Gate Activator. Tells the user what the data and capabilities within the Miridewatch are.
 * 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.

The Zi-O Ridewatch II consists of the following parts:
 * Ride On Starter II (ライドオンスターターⅡ) - The activation button. By entering this switch, it enters a standby state for connecting to the Ziku-Driver.
 * Outrigger Grip II (アウトリガーグリップⅡ) - The exterior body. It is shaped to stabilize the separation operation of the split leather and the loading operation into the Ziku-Driver by causing the fingers to function as a boom when held by hand.
 * Split Ryūzer (スプリットリューザー) - The separation device of the Zi-O Ridewatch II. By rotating it it separates into the D'9 Side (D'9サイド) and D'3 Side (D'3サイド).
 * Shiny Bezel (シャイニーベゼル) - The capability relief valve. By moving at the same time as separation, the ability of the Zi-O Ridewatch II D'3 Side becomes active
 * Pict Window (ピクトウィンドウ) - The monitor of the Zi-O Ridewatch II. Display capabilities of the Ridewatch with icons and other information such as time is communicated in the top window projected in space.
 * Glitter Window (グリッターウィンドウ) - The D'9 Side's graphic print of the watch. It is displayed simultaneously with separation, and the ability becomes active.

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.
