Great bit of kit.
Love it. Has everything I need as a hobby runner. The battery life is incredible, and the screen is easily viewable even on the sunniest days. Tip: buy screen protectors. I didn’t and now have a scratch which is quite deep- silky me. It is quite chunky. I have slim wrists and it doesn’t bother me, but might some - photo included (Stan says hi). Just wish the app wasn’t so pants.

Good
Very good watch. I use it to track my sleep and its useful to track your cycle as a woman. I didnt realise how 'stressed' i was.

much better comparing with old 245
used to own garmin 245 Music. switch to 255 as old one lost. bigger screen, and nice apps. turn on bluetooth, and hopefully it can last 9 days.

Excelente si haces triatlón
Si te quieres poner serio con tus entrenamientos necesitas uno si o sí, registrar todos tus entrenamientos es un paso importante para medir tu avance llevo ya 3 meses con el y junto con la aplicación Garmin Connect el producto se vuelve único, no sólo el reloj si no el ambiente completo, hice mi primer triatlón y quedé en noveno lugar, tiene todo lo necesario para marcar tu ritmo, tu paso, las transiciones etc. Te recomiendo comprar además la Banda HRM Pro+ para medir de mejor manera tus entrenamientos corriendo y nadando y si tu presupuesto te lo permite los pedales para bicicleta con potenciómetro. Tener un ambiente Garmin completo te permite medir absolutamente todo. Hablando de este reloj tiene todo lo que necesitas si quieres hacer triatlón, o solo correr, nadar o hacer ciclismo. Mide horas de sueño, estado de VFC, oxigenación en sangre, nivel de estrés, etc. Una vez que lo uses verás que las prestaciones de este reloj son todo lo que necesitas, por mi parte lo usaré un año más para después brincar un 965. Pero te juro que este reloj es perfecto.

Excellent Upgrade from the Forerunner 745
I’ve been a Garmin user for over 10 years, and I upgraded from the Forerunner 745 to the Forerunner 255. This is an excellent upgrade and immediately feels like a more refined and capable watch. The 255 is lighter and more comfortable to wear all day, and the battery life is noticeably better than the 745. I’m also seeing improved GPS accuracy and more consistent tracking overall. The updated metrics, including HRV status and the newer training insights, provide more useful data to support training and recovery. Performance is smooth, reliable, and exactly what I expect from Garmin. It keeps everything I liked about the 745 while improving the areas that matter most, especially battery life, comfort, and tracking accuracy. If you’re coming from the 745, the Forerunner 255 is absolutely a worthwhile upgrade. Highly recommended.
