## Description

Casio HS-80TW-1EF Digital Handheld Stopwatch measures with an accuracy of thousandth part seconds the meantime and the end time. Signals confirm the starting/stop selection. The measuring capacity reaches up to 10 hours. The referee function shows the current play time and the overall time which has already passed in the game, simplifying the calculation of injury time. Measured total, lap and split times can be stored in a memory with the date and can be displayed again later. A data set consists of: date, total, lap and split times. The memory has enough space for up to 100 data sets. Using this timer, up to nine individual countdown times can be defined and set to elapse in sequence. The daily alarm reminds you of events that recur every day, by emitting an audible signal at the set time. This model has twelve independent alarms that can be used flexibly to remind you of important appointments. Once set, the automatic calendar always displays the correct date. The acrylic is easy and relatively unbreakable. The resin housing is the ideal everyday companion. It is durable, lightweight and relatively insensitive to cold, heat or other external influences. The battery supplies the watch with sufficient energy for approximate five years. This watch can be worn when showering and bathing - it is tested for water resistance up to 5 bar according to ISO 22810.

I am a swimming coach and have had my fair share of various stopwatches. This piece is very well made and comes packed with most features you would need (it doesn't calculate a stroke rate, but you can do it yourself, so this doesn't bother me). For me the main thing is the robustness and reliability of the device, which are superb. Highly recommended!
