For serious swimming timing and coaching, we recommend the Fastime 14 if you want to store a series of split times in memory as segments. This means you do not have to recall and write down your memory data before starting the next event. This watch also has a stroke rate function.
If you need a more basic memory function, then consider a dual display stopwatch such as the Fastime 20 (10 lap memory). Or a triple display stopwatch such as the Fastime 9 (100 lap memory) with stroke rate. All our memory stopwatches have similar stopwatch functions but check them out for different additional functions such as the various timer options available.
If you would like to time up to 4 swimmers in an event look at the Multichron stopwatch. If you want a basic stopwatch look at the Fastime 01 entry level stopwatch or the Fastime 1. Both have the same functions but the Fastime 1 is more robust and has a bigger display.
