Description

The Garmin Forerunner 45S is a lightweight fitness-focused smartwatch that’s designed to help you reach more fitness goals. The Forerunner 45 is available in two sizes; a bigger 45 and smaller 45S. The difference comes in the sizes 39mm vs 42mm and each of these two is well equipped with lots of fitness tracking features that allow you to track and manage your active life effortlessly.

The Forerunner 45S has a 1.04 inch transflective LCD display that’s easy to read outdoors, although not so colorful. It’s not a touchscreen device, so you’ll have to depend on the 5 physical buttons that no doubt makes it easy to navigate.

This watch will keep connected to all that matters to you as well as being able to control music on your phone, find your phone and watch. The battery life is great, you can go up to 7 days from a single charge and about 13hrs with continuous GPS tracking.
