The timer is fully mechanical, so it is ready to use whenever you need a clear time limit for homework, routines, classroom activities, breaks, meetings or everyday tasks.Audible while it counts downThis timer makes an audible ticking sound throughout the countdown and rings a bell when time is up. That feedback can be useful when you want to hear time passing, but it may not suit people who prefer a non-ticking countdown.Up to 60 minutesSet the dial for any countdown up to 60 minutes. Its approximately 20 x 20 x 5 cm size makes the display easy to see from a desk, table or classroom space.Choose the timer that suits your spaceIf you want a battery-free timer with audible ticking, this is the better choice. If continuous ticking would be distracting, our Time Keeper Visual Timer does not continuously tick during the countdown, although it does have an audible end alarm.
