Technical Information

Up to 99hrs 59mins 59sec and 50 split times (split and lap). The stopwatch measures the following: 1/ split times = SPLIT: the time elapsed since the start, 2/ lap times = LAP:the time elapsed since the last lap time measurement.
When using the stopwatch, the first 50 split times and lap times are memorised. They can be recalled, whether the stopwatch is running or not.

Used for 1 week or less
I was expecting a bit more reliability for the price. As a time keeper at swimming galas, a reliable stop watch is essential when timing 100+ races, but this let met down too many times.
