Garmin Forerunner® 255, GPS Running Smartwatch, 46mm, Slate Gray

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.

I really am enjoying this watch. I'll start off by saying it I used to have an Apple watch but no longer have an iPhone so I was looking for an alternative. I've used Fitbit and apple watches and feel they are accurate at tracking things like heart rate and GPS. This watch feels the most accurate out of both of those. The Garmin app isn't as pretty and easy to use as Fitbit but the quality and information is so much better. Also the customization of this watch is insane. From multiple backgrounds to the way you can set up what information you want to see during any given workout is awesome. As you can tell by my watch face there is a great amount of information just by looking at the first screen and more if you scroll around. This is the 46mm case size and I really think it's the perfect balance between being able to see the information and not being too bulky. Obviously the tranflective display is not as pleasing as an AMOLED display like and apple watch, galaxy watch, pixel watch, or Garmins own venu or epix watches but it honestly is not that bad. Also I've heard of bad backlight reviews on the Garmin watches where the screen looks washed out and blue when the backlight is on and I think I got a good one. It's almost been two weeks and I'm still at 67% battery life. I have yet to swim with the watch but it feels like good quality and the gps has been accurate on my runs. I was thinking of getting a Fenix 6 since they are much cheaper now but the features and less bulkiness of this Garmin Forerunner 255 sold me. The gray color is okay but I might end up going with a different band style and color in the future. The video taken with the backlight on is with the brightness at 20%. Take your fitness goals to the next level and get this watch!

The Garmin Forerunner® 255S has truly become my absolute favorite smartwatch and has been a key tool through my fitness journey, here's why I love it: Adapting to My Workouts: Although labeled as a running smartwatch, it effortlessly fits into my diverse workout routine. Whether I'm hitting the gym, practicing yoga, or going for a nature walk, it tracks my progress with accuracy. Feels Like Nothing: The lightweight design is a game-changer. During workouts and even during sleep, I barely notice it's there, allowing me to focus solely on my routines. Accurate Insight: From heart rate monitoring to sleep tracking, it offers insights that help me tailor my workouts effectively and monitor my health data reliably and easily. Knowing I can rely on its data keeps me motivated. Part of My Day: Its sleek profile and customizable faces make it not just a workout companion, but an everyday accessory that reflects my style. No Worries About Charging: One thing I appreciate is its impressive battery life. It's a relief knowing I can wear it all day without needing to recharge constantly. For my use, it lasts 11 days before needing a charge. When It does need charging, it charges FAST! In short, the Garmin Forerunner® 255S is more than a gadget; it's a personal fitness partner. It adapts to my routine, offers accurate insights, and feels like a natural extension of my active lifestyle. Whether I'm lifting weights or running errands, it's a constant companion that helps me stay on track and motivated. I highly recommend this watch!

I’ve been using the Garmin Forerunner 255 for a few months now, and I’m genuinely impressed. It strikes a great balance between advanced performance features and everyday usability. The GPS accuracy is top-notch, thanks to the dual-frequency support, and I’ve had no issues with tracking even in areas with spotty reception like wooded trails or city streets. Battery life is a huge plus—it easily lasts close to two weeks in smartwatch mode and over a day with continuous GPS. The design is lightweight and comfortable for all-day wear, including during sleep tracking, and the five-button interface is simple and responsive (though I do sometimes miss having a touchscreen). Training features are where this watch really shines. It supports multiple sports modes, heart rate variability, stress tracking, and Garmin’s “Body Battery” to gauge overall energy levels. The race predictor, morning report, and recovery time estimates are surprisingly useful. Sleep tracking is detailed and generally accurate, and syncing with the Garmin Connect app is smooth. My only minor complaint is that you need the Music version if you want onboard music storage; otherwise, you're just controlling your phone’s playback. Also, no touchscreen might be a con for some, but the physical buttons work great in sweaty or wet conditions.

I have been using this watch for years and it really works great battery life for long runs the sleep feature is a surprisingly good estimate worth the price but don’t expect high tech features

I previously had a Garmin 235 that I had bought used, and it died. I finally bought myself a new Garmin. This thing is great, very basic, but solid and very accurate with the GPS. Battery life is awesome at 14+ days when not using GPS. It dips faster when you use it for running/volleyball, etc, but still gets like over a week when I'm working out 6-7 days before needing a charge. Holds battery way better than Apple watches, etc. Text, and messenger notifications come through great on the watch as well.

Great watch for runners. Sleep tracking not as accurate as other watches. Running metrics such as pace, stride length, hr, power are helpful info for improvement.

I LOVE this watch! That's really all there is to say. I had no issues with the seller or delivery. I'm writing this over a year after purchasing, and I have had not a single issue with the watch. Garmin is fantastic!

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.

Que es un reloj super, me encanta y de momento va perfecto

Todo correcto, ha tardado en llegar 2 dias menos de lo previsto, el reloj perfecto, va como tiene que ir, gps, mapas, etc. muy bien

Brilliant watch. Can do anything you want it to basically! I just need to figure out how to turn the training suggestions off, otherwise exactly what I was after!

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.
