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.

Method 1

 * 1) Confirm that an Another Rider exists during the present day, provided it was born during its original counterpart's debut year.
 * 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) **In episode 5, it is revealed that 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. However, the degree of change varies from Rider to Rider, due to the villains in most Kamen Rider series having origins independent of that of the Kamen Rider who eventually faces them, though evidence of their prior existence and impact are still being seen in the altered present.

Method 2

 * 1) Confirm that an Another Rider exists with Rider Powers within himself/herself.
 * 2) Hard-counter the Another Rider.
 * 3) The Rider Powers within the Another Rider will take the form of Ridewatches and will eject out of his/her body.

Method 3
In this method, the Transformation device of a Kamen Rider either transform into Ridewatches (like Decade, Hibiki, Kabuto, Den-O) or transfer their powers into a blank Ridewatch (like Kuuga, Ryuki, Knight, Agito). In majority of the cases, the Rider performs the creation with his own will, generally while giving their powers to Sougo, or the powers are taken away by someone, like Kuuga and Agito. In cases of Kabuto, Hibiki, Ryuki and Knight, the creation took place itself for unknown reasons.

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 or any other Kamen Rider from his series, however, Sougo and Geiz are able to obtain the Ryuki and Knight Ridewatches by simply having Shinji Kido in their presence due to the fact that all the Mirror Riders' powers were restored in 2019 in another Rider Fight. Also, because the Time Jackers were able to infuse Kamen Rider Ryuga's powers into the Anotherwatches, they too seem to have a way to bypass this alternate timeline restriction as well.

Miridewatch Creation
The Four Riders from the future, Shinobi, Quiz, Kikai, and Ginga do not exist in the present day, therefore it is impossible to obtain a Ridewatch from them in the way regular Ridewatches are received. Due to this, the process of creating Miridewatches are fundamentally different from its regular counterpart. Each of the future Riders has had their Miridewatch created using a unique method each time.

Shinobi Miridewatch

 * Another Shinobi was immaturely defeated, which allowed White Woz to use his book and turn the blank Miridewatch in his hand into the Shinobi Miridewatch.

Quiz Miridewatch

 * White Woz placed a blank Miridewatch on Mondo Douan, which had siphoned his powers into a fully functioning Quiz Miridewatch.

Kikai Miridewatch

 * Another Kikai had an accessible holographic keyboard on its chest-plate. By entering the correct password, WILL BE THE KING, White Woz created the Kikai Miridewatch.

Ginga Miridewatch

 * Of the four future Riders, Ginga is an anomaly, and as such the creation of Another Ginga would be impossible. The three main Riders are forced to collaborate with the Time Jackers in order to defeat Ginga. With the alien Rider defeated, Swartz seals Ginga's powers in a blank Miridewatch before Black Woz snatches the Ginga Miridewatch in the process.

Special/Personal Ridewatch Creation
Each Ridewatch formed in this manner either possess a unique standby tune, or insert into the D '3 slot of the Driver with music accompanying the standard tune.

Zi-O Ridewatch II

 * Created from the fusion of two Zi-O Ridewatches from the Real World and Mirror World.

GeizRevive Ridewatch

 * Created from the fusion of the Shinobi, Quiz, and Kikai Miridewatches.

Zi-OTrinity Ridewatch

 * Created from the fusion of the Zi-O II, GeizRevive, and the Woz Watches.

GrandZi-O Ridewatch

 * Created once all 19 Main Heisei Ridewatches are collected.

Tsukuyomi Ridewatch

 * Created by Ohma Zi-O by infusing some of his powers into a blank Ridewatch.

Ohma Zi-O Ridewatch

 * Manifested after Zi-O meets Ohma Zi-O and receives guidance from the latter.

Power Restoration
In a manner similar to, if a legend Rider holds and activates a corresponding Ridewatch, they will instantly regain their powers. In the case of Agito, the Ridewatch will turn into energy and apparently turn back into the Alter Ring. In Hibiki’s case, the transformation sequence will immediately occur when this happens. They can later volunteer to turn their powers back into the Ridewatch. The same instance happened to Tsukasa when he lost his powers to Swartz, leading him to request Sougo to return the Decade Watch, which contained half of his powers, and sucessfully regained his Neo Decadriver.

Destruction
In Episode 47, as of the result of the further space-time anomalies, each Heisei Rider history will crash into reality, represented by each Ridewatches' destruction, turning grey in color and cracked. As a result, previous Heisei era monsters and surprisingly architectural locations (Futo Tower & Yggdrasill Tower) were summoned, crashing into each other.

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.

The GeizRevive Ridewatch consists of the following parts:
 * Revive On Starter (リバイブオンスターター) - The activation button located on the top. Pressing it switches the Ridewatch into a standby state to be inserted into the Ziku-Driver.
 * Revive Circular (リバイブサーキュラー) - The front body. It's shape is meant to stabilise the Ridewatch's rotation when switching forms by letting the hand and fingers function as a boom.
 * Divide Window (ディバイドウィンドウ) - The 'hourglass' window. It is the main monitor. Each two blocks divided in the upper and lower sections stores strength and speed abilities separately via unknown means. Inside of the Divide Window are multiple Repaired Crystals (リペアードクリスタル) that gathers on the bottom half of the Divide Window no matter what form GeizRevive is in. When the GeizRevive Ridewatch is flipped around, the Repaired Crystals go into the opposite block in order to repair its system from any damage incurred.
 * Pict Face (ピクトフェイス) - A face within the GeizRevive Ridewatch's Divide Window. It informs people of what form the user is currently in.
 * Black Bumper Bezel (ブラックバンパーベゼル) - The frame that surrounds the Divide Window. In addition to high strength, it acts as a shock absorber, protecting inner mechanisms. Despite it's name, the Black Bumper Bezel is more of a dark metallic gray hue than an actual black color.

The Zi-OTrinity Ridewatch consists of the following parts:
 * Trinity Starter (トリニティスターター) - The startup button on top. By pressing it, the whole Ridewatch enters a standby mode.
 * Layered Lock Bezel (レイヤードロックベゼル) - The overall bezel. The Zi-OTrinity Ridewatch is divided into three layers; each layer providing protection for inner parts, as well as locking functions outside control range.
 * Pict Window (ピクトウィンドウ) - The graphic imprinted on the Zi-OTrinity Ridewatch; displays Zi-OTrinity's face. It can holographically transmit information.
 * Unite Ryuzer (ユナイトリューザー) - The ability release valve located on the right side. By rotating it, the Zi-OTrinity Ridewatch opens up layer by layer, releasing more power per layer.
 * Oversight Clock (オーバーザイトクロック) - A clock face that extends over the Ziku-Driver's middle section. As the Unite Ryuzer is turned, each layer of the Zi-OTrinity Ridewatch is flipped, forming the Oversight Clock. By aligning itself with the Ziku-Driver's axis, the Driver's processing power is increased 1.5 times. This allows the user to safely use the high-impact Zi-OTrinity Ridewatch.
 * Trinity Grip (トリニティグリップ) - The Zi-OTrinity Ridewatch's overall exterior. The shape stabilizes the rotation motion of the Wake Bezel and loading of Ridewatch into the Ziku Driver. Out of all the preceding Ridewatches (and Miridewatches), it boasts the most protective strength.

The Ginga 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.
 * Connecting Slider (コネクティングスライダー) - A joint for connecting the Miridewatch to the slot of the BeyonDriver. The number and arrangement of the connectors differ depending on the characteristics of the Miridewatch.
 * Revolute Selecter (レボリュートセレクター) - The watch's selection device. The icon on the surface shows the ability of each form, and the desired icon to the center of the Miride Scope.
 * Miride Scope (ミライドスコープ) - The watch's ability release valve. The icon that fits in the center of the scope has a role to release the ability to represent.
 * Orbital Reel (オービタルリール) - The Ginga Miridewatch's reinforced frame. It increases the rigidity of the enlarged Ginga Miridewatch and also serves as a guide rail for the Revolute Selector.
 * Ginga Armor (ギンガアーマー) - The Ginga Miridewatch's overall armor. It is made from cemented carbide that cannot be purified under gravity, and is very dense and robust.
 * Send Projector (センドプロジェクター) - The screen. When the Miridewatch is loaded into the BeyonDriver, the Send Projector transmits data into it via super high-speed optical signals.
 * Half Outrigger Grip (ハーフアウトリガーグリップ) - The Ginga Miridewatch's overall exterior. It has a shape to stabilize the loading operation to the BeyonDriver by making the finger function as a boom when holding by hand.

The GrandZi-O Ridewatch consists of the following parts:
 * Grand Starter (グランドスターター) - The activation button. By pressing this switch, it enters a standby state for connecting to the Ziku-Driver, and the Glory Small is revealed on both sides.
 * Grand Grip (グランドグリップ) - The exterior body. When holding by hand and by making the finger function as a boom, it is shaped to stabilize the loading operation to the Ziku-Driver.
 * Complication Bezel (コンプリケーションベゼル) - In order to hold down the enormous internal power equivalent to 20 Ride watches, Zavaldust Graphenium is used, and each ability is controlled by arranging many control devices.
 * Pict Window (ピクトウィンドウ) - The main monitor of the GrandZi-O Ridewatch.The ability of Ridewatch is displayed as icons, and other information such as time is transmitted in the top window projected to space.
 * Glory Small (グローリースモール) - The ability release valve of the GrandZi-O Ridewatch. It shows the ability of the Ridewatch deployed and assembled on both wings.
 * Second Controller (セコンドコントローラー) - The control device. Twenty large and small pieces are placed to control the power of successive Ridewatches and supply them in a state most suitable for GrandZi-O.

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.

However, some Ridewatches lack a Wake Bezel, in which case the depending Starter is pressed before being inserted into the Ziku-Driver.

A Miridewatch works similarly to a Ridewatch. However, due to a lack of a Wake Bezel, the Miridewatch is activated merely be pressing the Miride On Starter before inserting it on the BeyonDriver. Pressing the Miride On Starter again will open the Miridewatch's Gate Activator, exposing the Send Projector and allowing the Beyondriver to be closed.

Special Ridewatches have extra steps to activate. For example, the Zi-O Ridewatch II's Ride On Starter II is pressed before being split into two pieces by the Split Ryuzer.

The GeizRevive Ridewatch, after pushing the Revive On Starter button, can be inserted into the Ziku-Driver to transform into Kamen Rider GeizRevive. To change forms, the user merely rotates the entire Ridewatch's face without removing it.

The Zi-OTrinity Ridewatch, after being inserted into the Ziku-Driver's D '3 slot, requires the Unite Ryuzer to be turned twice, revealing faces of Kamen Riders, Geiz and Woz before activating the transformation into Zi-OTrinity. The finisher is determined by how many times the Trinity Starter is pressed, from once to thrice, before rotating the Driver.
