The POLAR M62 heart rate monitor is waterproof to a depth of 30m and comes with a heart rate sensor and belt. - The battery is dead, so it's unknown if it works. - The rubber part of the belt is deteriorated and unusable, but it's connected to the nylon part and other components, so it can be replaced if you can sew. - It has been used very little, so apart from the belt, it is almost scratch-free and clean. - Brand: POLAR - Model: M62 - Accessories: Heart rate sensor, belt, instruction manual - Waterproof performance: Waterproof to a depth of 30m - Coding: 31 Coded Thank you for viewing.
