MOSTRUST Digital Simple Waterproof Stopwatch with On/Off, No Bells, No Clock, No Date, Only Basic Silent Stopwatch Large Display for Swimming Sports Kids Coaches (Black)

【Only Stopwatch Mode】: While most stopwatches on the market contain extras, like time, date, alarm; our customers told us that they never use them and it makes the stopwatch more complicated to use and set up. So, we listened, and have removed them completely. Additionally, we have increased the display size and added an on/off switch, just what our customers asked for.
【Very Simple to Operate】: The Digital Stop Watch is single lap and very simple to operate with minimal key presses to control: Start/Stop, Reset and On/Off button. The counter contains minutes, seconds and 1/100th seconds.
【IPX8 Waterproof Stopwatch】: This MOSTRUST stopwatch is 50M waterproof which can be used underwater when swimming, but can not be diving. It is designed for swimming coaches, durable and high quality, which can effectively improve the use time of the product.
【ON/OFF with Battery】: The Stop watch has on/off function with one CR2032 battery.
【Absolutely Silent Stopwatch】: The stopwatch has a good design with piano key button, and you will feel comfortable and compact in your hands. The stopwatch is absolutely silent, there is no noise when you press any button or counting.
