I don't know why, but I keep having ideas one after the other.

Name: Clock Back

Nen Type: Conjuration

Description: The user conjures a golden pocket watch. On the clock face, this is indicated as "M0", "Moment Zero", the point from which the single clock hand starts moving; it takes it 12 minutes to go back to M0. Within the next 12 minutes,  which is the time it takes the clock hand to strike M0 again, the user can close the pocket watch to revert to the exact conditions he/she was in at M0. Wounds, fatigue and any kind of Nen ability will disappear immediately, provided they haven't been inflicted before M0 (for example, if Knuckle's "Hakoware" had been attached before that, it would not disappear, but the count would go down to match that at M0), including pre-existing wounds and fatigue. The only thing that is not restored is the user's aura. This makes it ideal for kamikaze attacks, provided the user does not die before he/she can close the pocket watch. Once the user "rewinds", the pocket watch disappears.

As in a normal clock, it takes the clock hand exactly 60 "tics" to go back to M0. Each "tic" corresponds to 1/60th of the aura the user possessed at M0. When he/she decides to close the watch, if the clock hand has made 27 "tics", then 27/60th of the aura originally possessed by the user will be consumed. However, between the conjuration of the watch and the activation of the effect, the user will have most likely used some aura to fight. The consumption of aura is indicated by a second, smaller clock hand that moves counter-clockwise. The area from M0 to its current position corresponds to the amount of original aura the user has consumed, and goes by the name of "Lacking Zone". If the larger clock hand enters this area, it means that from that moment the user will not have enough aura to activate the ability. The safest way to deactivate the ability would thus be to wait for 12 minutes without "rewinding".

Limitations:

1- After 12 minutes the pocket watch will disappear automatically without its effect activating. Same if it  is damaged in such way that the movement of the clock hand is compromised.

2- Once the ability is activated, it cannot be used again before 24 hours pass from the exact moment the clock was conjured.

3- Should the user lose consciousness before being able to close it, the pocket watch will disappear without the ability activating.

4-  Should the user decide to "rewind" after the larger clock hand has entered the Lacking Zone, they will be able to do so, but the clock will not disappear; instead, it will keep existing and become indestructible until the clock hand strikes M0. At that moment, every condition that has been removed will reappear (unless it is a Nen ability and its user has been killed in the meanwhile). Furthermore, the percentage of aura that the user lacked when he/she "rewinded" will be deducted from their full amount of aura and become unusable forever.

5-  The portion of surface between M0 and AP, "Activation Point", is equal to 1/12th of the clock face's area. It is called "Negative Zone" and colored red. In the minute the clock hand is in that area, the effect of the ability cannot be activated.

6- Every time the ability is activated, the Negative Zone increases by 1/12th of the total surface: meaning if is occupied just 1/12th of the clock face at first use, it will increase to 2/12th at the second, then 3/12th at the third, and so on. The twelfth time the ability is used, the pocket watch will be successfully conjured, but it will be entirely red and it will be impossible to use it. 24 hours afterwards, the Negative Zone will again be equal to 1/12th of the total area.
