Kaltor

Other Kronoforms might be thinkers or lovers, but Kaltor is clearly a fighter.

Kaltor is an Autobot from the Generation 1 era.

Kaltor transforms from a robot to a time machine styled after a Human calculator watch.

It is unknown whether he needed to be in watch mode to travel in time, or if he was able to access the ability in both modes.

Toy

Kaltor was designated a Kronoform toy on his package, and originated in the same japanese Microman subline that spawned Scorpia and most of the other Transformer watches, as well as scores of knockoffs. Like most of the Official Transformers watches Kaltor is rather rare.
