Speed Gauge (Earth-Prime)

The Speed Gauge is a watch-like device created for Barry Allen to monitor his speed usage after the Death of the Speed Force.

History
In 2020, Speed Force died after The Spectre infected the Speed Force with spectre energy which unbalanced the energy in Speed Force. Later, Cisco built the Speed Gauge for Barry in order to use his residue speed wisely.

Design
The gauge is in the appearance of a watch and emits green, yellow and red when Barry uses his speed to much. The color is currently red after "Iris" kicked Barry out of their apartment.
