Polar WearLink (sensor model 31) and adjustable chest strap for adding HRM (heart rate monitor) functionality to Polar brand running watch (model RS400)

Probably used about 10 times (just for races) before I lost the RS-400 watch.
Chest strap hand-washed after each race.

Includes sensor, chest strap, and owners manual (for the watch, which shows how to use the HRM transmitter).
