The Swimovate Pool Mate 2 swim sports watch is at home both in the pool & in open water thanks to its swim pedometer mode that measures distance & speed outdoors. In the swimming pool it will display laps, sets, strokes, distance, time, speed, calories, & efficiency levels in large characters on the crystal glass face. It has a great battery life of 24 months & a 99 set chrono mode for use in other activities. The memory will store & recall 50 sessions worth of stats including individual sets & total session data, & the watch, which is designed for use in pools over 18m long, has an alarm, a 24 hour clock & is water resistant to 50m (164ft).
