This is an adjustable planning example, not a scientifically established best duration or productivity claim.
Exact duration
39 minutes = 2,340 seconds = 00:39:00. The digits show hours, minutes and seconds. At 60 minutes the preset is 01:00:00, not 00:60:00.
00:39:00
Open the preset and start
Choose the timer or stopwatch link. It fills the duration or goal without starting. Check the display and press Start. A timer preset uses an empty or new workspace so another saved timer is preserved.

The stopwatch counts up from zero with a 39 minutes goal. Record laps while running. Reaching the goal changes the status without stopping or playing a sound. Goal sessions have separate saved records from the ordinary stopwatch.
