Hour / Tach meter

The tachometer, also known as the rev counter, indicates the speed at which an engine is operating in revolutions per minute (RPM). It is usually displayed on the dashboard or near the steering wheel for easy access while driving. The hour hand, on the other hand, shows the time of day and helps in keeping track of how long a vehicle has been running. Together, these two instruments provide valuable information to the driver about the engine's performance and the duration of use.
