Simple ideas are always the best ones; introducing the worlds first rechargeable stopwatch!!! Our research showed a sway of teacher disappointment at having to discard stopwatches once batteries had expired. Now you don't have to ever again; the recharging facility ensures you can stop worrying about watches having been left on and being useless when you need them most! We have added another 'teacher idea' feature whereby you can set the stopwatch to show either seconds, seconds / tenths and seconds, tenths and hundredths - 3 stopwatches in one! The pack contains 12 rechargeable stopwatches in bright colours, matching removable lanyards, docking station and mains adaptor - all for the price of 12 normal stopwatches - that is a fantastic offer.
