Hyper Clock Up
The Hyper Zecter allows access to Hyper Clock Up (ハイパークロックアップ), an upgraded version of Clock Up, able to even time travel due to its hypersonic speed properties and the Maximum Rider Power by pushing the horn of the Hyper Zecter again to maximize the power of his finishing attack.

Decade
The Clock Up Attack Ride Card can be used by Kamen Rider Decade when he transforms into Kabuto. As Kabuto, Decade moves extremely fast to the point that seconds slow down into minutes. When this attack is used in Kabuto form, Kabuto Zecter's voice will be played. But Decadriver's voice will be played insteads if Tsukasa stays in his Decade form. In the novel reimagination, Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~, the card somehow ended up in Tendou's possession and give it to Tsukasa after he realized that he is Decade with the card itself being used by Decade while in Kuuga Mighty Form.
 * With the Hyper Clock Up Attack Ride Card, as Kabuto Hyper Form, Decade is able travel at near light speeds, allowing him to travel forward or backward through time. This card is not shown in the TV series, but is used in the S.I.C. Hero Saga side story published in Hobby Japan magazine.

In the World of Kabuto, Tsukasa is given the ability to see in Clock Up space. Daiki's treasure in this world is the Clock Up System.

Counters
Clock Up's ability is to move at fast speed and within the crossovers of the Kamen Rider multiverse, there are those with the ability to counter or match the speed of Clock Up.


 * Starting off with Kamen Rider Faiz, in a showdown with the Kamen Rider Decade series, Decade transforms into Faiz Axel and utilizes the form's super speed to combat the ZECT Riders' Clock Up. Though Faiz Axel has been noted to move at the speed of sound while Clock Up has been noted to move slightly slower than the speed of light, Hyper Clock Up was still slower than the speed of light making the actual speed of a regular Clock Up to be around the speed of sound.
 * In the finale of Kamen Rider Wizard, Faiz Axel and Kabuto both moved at the same speed.
 * Faiz Axel has been shown in a speed match against Kabuto again in.
 * Kuuga Pegasus's heightened senses can allow him to combat foes that can move at Clock Up speeds.
 * Decade, while transformed as Kabuto, was matched evenly against 's super speed.
 * In Kamen Rider Decade, there exists a Clock-Down generator, created by Sou Otogiri. Once activated it can disable users from using Clock-Up, thus slowing them back down to normal human speed.
 * Kamen Rider Stronger has been shown to temporarily halt the Clock Up function with a "Radial attack"..
 * Kamen Rider OOO's Super Tatoba Combo has the ability to displace himself in time momentarily giving him the appearance of teleportation and super speed.
 * The ability of Heavy Acceleration distorts time, making anyone in its radius to feel heavier and more sluggish, which would either hinder or negate the speed of Clock Up.

In theory, if a Rider who used Clock Up attacked an opponent whose power and defense greatly outclasses the attacking Rider's own strength, it would more likely result in the attacking Rider being hurt instead.

In popular culture

 * Episode 327-B the comedy anime Sgt. Frog (ケロロ軍曹) titled "Keroro, Invasion in a Blink!" features the members of the Keroro Platoon trying to invade Earth in Clock Up mode.
 * In Haiyore! Nyaruko-san, Clock Up is officially listed as one of Nyarko's unique powers, though she has yet to demonstrate it. However, it's referenced in the first episode when Mahiro asks how Nyarko had time to make him a box lunch that morning and she replies "A Clocked-Up Nyarlathotepian can move at speeds that defy all logic!" (Both the Crunchyroll and NISA versions mistranslates Clock Up as "overclocked", but this could be the result of a licensing issue.)  The ability is referenced again in the Nyaruko-san game for Play Station Portable.
 * In Angry Birds Toons episode 1 "Chuck Time", the power of Chuck's headband gives him an ability not unlike the Clock Up. He used this power to slow down the falling Red while slowing down time, right down to filling a barrel with water, not realizing that the water flows very slowly due to the slowing down of time and Red had fallen away from where the barrel is in the end.
 * Though unseen encountering with some ZECT Riders or Worms, Alternatives equipped with Accel Vent, Zect Riders Rider Form in Clock Up. Diend while equipped with the Tesla Band Activation, Accel Trial, OOO Super Tatoba Combo, Wizard Infinity Style, Gaim Jimber Cherry Arms, Drive Type Speed & Formula and Zutto Mach are counted to counter the system due to their inheritance of speed up or/and time-traveling abilities.
 * Although Diend did encounter Nega World's Dark Kabuto, they didn't speed clash as Dark Kabuto didn't use Clock Up to counter Diend's speed ability.
