Ridewatches

The 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. 
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.
However, Junichiro Tokiwa was later able to fix the Ridewatches solely using his skills as a horologist. Despite the timeline being reset, the Ridewatches continue to exist in some form due to elements of the original timeline spilling over, caused by further anomalies within the time stream. 
===Creation===
;Method 1
The Ridewatches of the main Heisei-era Riders can be created through a causal temporal loop, as Sougo receives the fully manifested Ridewatch from the legacy Rider in present day and defeats their Another Rider counterparts in the past before giving the legacy Rider of that past a blank watch which will ultimately manifest into the one Sougo's past counterpart receives in the future. 
While typically used to fight against the Time Jackers and the Another Riders, Woz states that this method has severe consequences as it permanently alters the timeline and "steals history", presenting a sinister aspect to this method as Riders lose their memories and powers upon Zi-O or Geiz's first usage of the respective Ridewatch. The degree of change varies from Rider to Rider, due to the villains in most Kamen Rider series having origins independent from 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
Occasionally, Another Riders who appear in the present day can spawn Ridewatches from their bodies, provided that Sougo and Geiz have met the conditions for them to do so. 
;Method 3
Similar to the used by the , legacy Riders can turn their transformation devices into a Ridewatch, which is typically done of their own free will in order to pass it on to Sougo, or forcibly robbed by someone like a Time Jacker. Vice versa, Tsukasa is shown to have turned Decade Ridewatch back into the NeoDecadriver for his own use, stating he was able to choose the quantity of his powers to be transferred initially.
*In the case of Ryuki and Knight, their Ridewatches were created when Shinji Kido sought help from Sougo and Geiz. 
*In the case of Agito, the Ridewatch will turn into energy and apparently turn back into the Altering. . In Hibiki's case, the transformation will occur immediately.
*The Hibiki and Kabuto Ridewatches were created in the presence of an individual who was deemed to have inherited the wills of the Riders they were associated with (namely Kyosuke Kiriya and Arata Kagami respectively). Behind-the-scenes, this rule was created due to the unavailability of the lead actors. 
;Restrictions
Since the creation of a Ridewatch involves time travel, they can only be created if the user is able to access to the origin of their powers, such as using a time machine to travel to the past. However, it is more difficult, if not impossible, to come in contact with Rider powers originating from alternate or erased/alternate continuities unless a denizen from there seeks it first. This was initially the case with all the Riders from Kamen Rider Ryuki as their powers originate from Mirror World until they were temporarily restored outside of it in 2019. It seems that if one is able to siphon the powers of Rider from another world or erased timeline, they can bypass this restriction as shown with the Time Jackers and their dealings with Another Ryuga.
===Miridewatch Creation===
Because normal Ridewatches are created from absorbing powers of the past, it is essentially impossible to obtain a Ridewatch from Kamen Riders of the future using time travel, as they technically do not exist at this point in time. Due to this, the process of creating a Ridewatch from future Riders are fundamentally different from its regular counterpart. Miridewatches based on Rider from the future do not necessarily share the same method, as seen with the four future Riders in the series. 
*Shinobi Miridewatch: Sougo convinced Rentaro Kagura to trust himself to be Kamen Rider Shinobi in future, which allowed White Woz to use his Future Note to write down , and turned 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===
Aside from Ridewatches based on other Riders, the Kamen Riders of Kamen Rider Zi-O possess their own personal Ridewatches based on essentially themselves, each created using methods unique to their own. 
*Zi-O Ridewatch: Created from a blank Ridewatch after Sougo became determined to change his fate.
*Zi-O II Ridewatch: Created from the fusion of two Zi-O Ridewatches from both the real world and Mirror World.
*GeizRevive Ridewatch: Created from the fusion of the Shinobi, Quiz, and Kikai Miridewatches.
*GeizMajesty Ridewatch: Created from the fusion of Diend's secondary rider Rider Cards from G3 to Geiz.
*Zi-OTrinity Ridewatch: Created from the fusion of the Zi-O II, GeizRevive, and the Woz (Mi)Ridewatches.
*GrandZi-O Ridewatch: Created from the physical presence of all 19 Main Heisei Ridewatches, regardless of its original method of obtainment. 
*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.
*Woz Ridewatch: Manifested during the time Red Woz reverted back into Black Woz.
==Design==
A standard Ridewatch consists of the following parts:
* - 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.
* - The overall exterior body of the Ridewatch. The shape stabilizes the rotation motion of the Wake Bezel and loading the Ridewatch into the Ziku Driver.
* - 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.
A standard Miridewatch consists of the following parts:
* - The activation button located on the top. When pressed, the Miridewatch enters a standby state to prepare itself for insertion into the Beyondriver.
* - The exterior body. The shape stabilizes loading operation into the Beyondriver by letting the user's fingers grasp the Miridewatch in a comfortable manner.
* - 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 its data.
* - The graphics printed on the Gate Activator. Tells the user what the data and capabilities within the Miridewatch are.
* - 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.
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 by 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.

==Notes==
*It was explained in the second episode that multiple instances of the Rider's powers cannot co-exist at the same time. With past instances such as Rider powers being replicated (Fullbottles, for example) and a Rider having multiple known civilian identities (Zangetsu Shin, Faiz, etc), the Ridewatches most likely erases the Rider's primary civilian identity rather than the power-set itself. Certain individuals seem to be immune to this such as Tsukasa Kadoya, though the reason could be that he's originates from a different universe. 
**This is implied through the Gaim tribute arc when Sougo with the Gaim Ridewatch in his possession crosses his own timeline, which doesn't erase any of their powers. The Ridewatches themselves could also have some sort of shielding from the instability of the contained powers when an Another Rider exists, which would explain how a future Zi-O could appear with his own Gaim Ridewatch, without causing power fluctuations.
*The years labeled on Ridewatches refer to the debut year of the series in which the Rider appears, rather than the year in which the Rider appears. The exception is Amazon Neo, who debuted in a separate season.
*Whereas the transformation announcements of normal Legend Rider Ridewatches feature a recycled transformation announcement from the Rider followed by the Ridewatch's voice stating the Riders name, Final Form Ridewatches feature a unique jingle, then the Rider's name, and finally the reused transformation announcement.
*Faiz, Meteor, Beast, and arguably Decade are the only Riders with more than one form who have all of their forms represented as Ridewatches.
*Out of all the Ridewatches:
** Cross-Z, Genm, and Zero-One are the only Ridewatches with the rotating dial of DX Ridewatches but non-DX functionality.
**OOO Tajadol Combo, W FangJoker, Build RabbitTank Hazard Form, and Faiz Axel Form are the only super form Ridewatches to have DX releases.
**G3-X, Knight, Kaixa, Garren, Ibuki, Gatack, Zeronos, Ixa, Accel, Birth, Meteor, Beast, Baron, Mach, Specter, and Brave are the only Ridewatches to have rotating dials in official media but not in the toy line.
**Grease, Chalice, Eternal, Poppy, Cronus, Ouja, Scissors, and Dark Kiva are the only non-Main or Secondary Riders to have DX Ridewatches.
**Diend is the only Secondary Rider to have a DX Ridewatch.
**Biorider and Roborider are the only alternate form Ridewatches to appear in media.
**Zangetsu Kachidoki Arms, Cross-Z Charge and Genm Zombie Gamer are the only DX Ridewatches of non-Main Rider power-ups.
**Eternal and Skull are the only movie-exclusive Riders to have Ridewatches.
** Kaixa, Snipe Simulation Gamer and Amazon Omega are the only Ridewatches to include two phrases from the transformation sound as opposed to only one.
**Zangetsu Kachidoki Arms is the only Legend Rider Ridewatch to play voice lines from the corresponding Legend Rider.
**Geats is the only Ridewatch whose transformation voice-line adds an additional suffix after the announcement of the Rider. In this case, the transformation announcement ends with "Ready... fight!" 
*Many Ridewatches possess sounds that are strange among other ones from the same series.
**The Ghost Toucon Boost Damashii Ridewatch is the only Ridewatch from Kamen Rider Ghost that uses the phrase "Omega Drive" as the finishing attack while other Ridewatches from the series only use "Omega", or "Omega" with an additional prefix in the case of Ghost Grateful Damashii and Ghost Mugen Damashii.
**The Drive Type Formula Ridewatch uses the "Type Formula!" sound from the Drive Driver, while the Drive Type Dead Heat and Drive Type Tridoron Ridewatches omit the "Type" portion of the announcement.
**The Garren Ridewatch does not use any voice lines from Garren's arsenal in its transformation announcement.
**Unlike all other Ridewatches based on Ex-Aid, the Poppy, Cronus, and Genm Zombie Gamer Ridewatches don't use "Critical" as their fininsher announcements. Instead, they use "Toki Meki", "Zeppan", and "Dead" respectively.
**Unlike the Faiz and Delta Ridewatches, the Kaixa Ridewatch plays his Driver's "Standing By!" voice line in addition to "Complete!".
*The unique music played throughout many of the Ridewatches are based on the soundtrack and equipment of the series they originate fromhttps://youtube.com/watch?v=u2N0SpFqTEEhttps://youtu.be/JR98E7NJJgs:
