Overview

A lightweight GPS watch from Polar, weighing about 40 grams and finished in purple, part of Polar's line of sport watches built for tracking runs and workouts on the wrist.

Category and title agree this is a running or fitness GPS watch rather than an unrelated wearable. Beyond weight and color, the available spec sheet does not list battery life, screen type, or specific sport modes, so those details sit in the product page's fuller spec table.
