TTS Battery Stopwatch
Simple stopwatch with large screen which can be made age and key stage appropriate.
Change the settings, so that the timer will show either minutes only or with seconds or tenths. The on/off button is contained at the top so cannot be easily reset. Battery powered.
Each stopwatch requires 1 x coin cell battery.
Keeps a 3 year old entertained for ages. Easy to use. Good value for money.
