480 minutes
A timer for 480 minutes, or exactly eight hours, allows you to track an entire work shift or a long training marathon. Interface without unnecessary details: Start, Pause and Reset are located in plain sight and work without delays. At the end, the selected melody sounds, the sound is adjusted or turned off. The built-in time translator instantly shows 480 minutes in seconds and standard hour format.
