What Customers Say

Reviewers praised the Forerunner 255 Music for its accurate GPS and heart‑rate sensors and its ability to support triathlon and multisport modes, making it a versatile option for serious runners. They liked being able to store and play music offline and noted that battery life can stretch to nearly two weeks in watch mode. However, there’s no touchscreen; the interface relies on five buttons and can feel cumbersome, and the watch lacks features such as ECG and training readiness scores. Smartwatch functions are limited and it uses a proprietary charger with no wireless option. It’s a strong choice for endurance athletes who prioritise performance metrics over convenience.
