There is a thermometer under the time dial that shows how hot or cold it is. A mega bright blue LED at the top brings light to the darkness. Last but not least, the screw-off magnifier (cover on the dial) puts the little ones into the limelight! What a watch! Quartz clockwork with fluorescent hands. Comes with a large, robust snap hook so it can be attached to belt loops. Easy to reach and looks so cool. Made from anodised aluminium. Nickel free, splash-proof. Batteries incl. Watch size (not including snap hook): 6cm L, 4.5cm W.
