Seiko Swimming Master Black

The Seiko Stopwatch S141 is a stopwatch with a "pitch measurement function" that easily measures and digitally displays the pitch (strokes) per minute. It also features a "large three-line display panel" that allows you to simultaneously check split, lap, and total time or running lap time, as well as a "memory function" for measurement data. With 10 ATM water resistance, it can be used with confidence in rainy weather or during water-related sports. (Ideal for swimming, rowing, and water sports.)
