## Description

Garmin Forerunner® 255S, Smaller GPS Running Smartwatch, Advanced Insights, Long-Lasting Battery, Powder Gray

Review: 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.
Review: Get 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.

### ⭐⭐⭐⭐⭐ Absolutely love this watch as an activity and wellness tool
*by K***D on September 4, 2023*

I am not a runner but I have been considering a Garmin watch for a long time because I am usually an active hiker. I haven't been as active for a while and I feel like the wellness tracking this device offers is helping me back on track. This has been one of those purchases that I wish I had pulled the trigger on sooner now that I have it. Combined with the web app I really love the amount of detail that I can get and the variety of things I can easily track. I've found the GPS tracking on my longer walks to be very accurate so far. I also enjoy the variety of customization options both native to the watch and through Connect IQ score. I know that the sleep, stress, body battery, etc, are not the most accurate, but they are still a great tool for getting a rough idea of where I can improve. For me, being called out by something as neutral as data is very helpful and I appreciate being able to see trends and make note of things that I could change for the better. I do have to take some of the body measurements with a grain of salt because of medications that I take, like the HRV-based stress readings (always high for me), so you should take that into consideration if you are prescribed any kind of medication that either stimulates or sedates. I am so glad I went with the smaller model, I am a petite person and it feels like the perfect size for my wrist. I don't find it to be obtrusive at all. I don't love the silicone band and went with an alternative that looks better at the office and doesn't bother my skin as much.
