5.0 out of 5 stars Great training tool for runners.
Reviewed in the United States on July 30, 2024
I’ve owned Garmins before and find the ability to objectively gauge and plan your training is a powerful tool. This watch takes it to the next level compared to my old ones. You get essentially the Forerunner 265 here minus the Amoled screen and the training readiness metric. Here’s a hint, look at your body battery and recovery metric and you have pretty much training readiness nailed down. The biometric sensors of the 255 and 265 are the same.

Activity tracking is light years beyond Fitbit and also stock Apple Watched. Hell, having 5 buttons blows any Apple Watch out of the water for running. You can just hit an activity and go, or take a recommended workout. You can also make your own routines and upload to to the watch. I had some workouts from when I last owned a Garmin that I designed 10 years ago, and was able to upload and run them. I principally use it for running and strength training. For running I can’t find any faults for me. For strength training my complaint is the list of strength exercises is missing common exercises, like any read deltoid exercises…. It has an exhaustive list of odd ones too. Worst of all, you can’t make new ones. You can just use an existing one that is close enough and make a note that exercise X is really the one you did…. The watch also does a good job tracking indoor runs and both indoor and outdoor walks. It is pretty accurate in automatically detecting activities like impromptu walks, as well.

The MIPs screen is amazing outdoors and way better at night when you would don’t want to blast your face looking at the time. In mixed-level indoor lighting, it lacks compared to AMOLED. It doesn’t have the pretty colors nor the contrast indoors, but I like a more serious looking watch anyway and find AMOLED to look like a game. The battery life is amazing. To get this sort of life on the 265 you have to let face go dark when inactive and use gestures to wake it. Not a big deal, but nice to be able to see the watch with a side glimpse without having to raise hand all the time.

Customization is great. I downloaded a watch face that allows me to put all the metrics I need and have the time highly visible. Data screens are also very customizable. I have downloaded a custom data screen for running and for strength training to supplement the default screens.

This isn’t a Pixel watch or an Apple Watch. As a smart watch it has limited ability and that’s fine. It reliably shows notifications. If you have your phone with you, you can initiate contact with an emergency contact. For example, you can send a message to come get picked up. If you have a compatible bank or credit card, you can use Garmin pay. I do find my financial institutions don’t currently support it, though.

The music functionality is flawless. I use it with Spotify and a pair of JBL earbuds. It’s nice to be able to run with just the watch and earbuds and not have to carry a phone for music.

I was able to use my ANT heart rate strap and foot pod from 13 years ago with no issues. They sync quickly and stay synced. The onboard wrist heart rate and running dynamics functionality have been very good when I haven’t used my ANT accessories. So there is no need to get an HR strap, but if you have or want one, they work flawlessly.

The Garmin ecosystem; the watch, Garmin Connect App, and the website are great. Highly customizable and reliable. I had most recently used Fitbit and found the experience with the app and its website to be headed in a negative direction this last year.

Overall, I highly recommend this watch. If the price difference between this and the 265 is around $50, it’s a hard decision. It boils down to how you feel about AMOLED versus MIPS, and maybe the chance that 265 feature set continues to get updated a bit longer than the 255. When the price delta is above $50…. The 265 becomes hard to justify and the 255 is the obvious choice. To reiterate, training readiness isn’t worth much at all. It’s a combination of other metrics that are already on both watches. So the decision is simply AMOLED vs MIPS display versus price.

5.0 out of 5 stars Slight overkill for the non-elites
Reviewed in the United States on May 8, 2024
Watch is top quality with a bunch of bells and whistles. I really only needed a watch to stop me from having to hold my phone on runs.

All the extra features are nice to haves and have allowed me to look at my training from a professional outlook however I know where I am at. Combined with the strava app (or whatever app you want) it maintains tracking information well and accurate.

Battery life is almost never ending, with a nice low profile appearance. I will classify this watch as perfect for its price point and as a "better to have it and not need it than need it and not have it" purchase.

Reviewed in the United States on July 31, 2024
Great watch, fits very well (male wrist). Smaller face (255S) may work for others. No problems (yet) playing music while I run. Lots of battery life. No problems swimming w/it either. Cool features with tons of great info. I wish Garmin had access to a bunch of other apps, but what I do get is perfect for what I need. Overall a great purchase.

5.0 out of 5 stars The best watch for a runner yet!
Reviewed in the United States on May 1, 2024
I've been running with garmin for over 10 years now and it keeps getting better. The updates from the garmin forerunner 245 are noticeable and the technology in this watch is outstanding. There are plenty of apps to connect the watch to, whether it's running to tennis it has a mode for it. The watch is light and responsive with every button pressed. The GPS signal is strong and accurate and the wrist HR is dead on. I'm going to be honest, I'll never get a garmin with out a music mode to it. It's super clutch to run around with Spotify Playlist loaded on my watch without my phone being needed. Additionally, if you do carry your phone while completing an activity and you happen to fall, there is an incident detection and will contact a designated person on your liat with accurate gps coordinates to you location.

This watch is amazing and does everything you need it to do, and more !

4.0 out of 5 stars The watch that finally replaced my Pebble
Reviewed in the United States on April 23, 2024
I'll probably go back to my trusty Pebble Time Steel from time to time (no pun intended... that time). You just can't beat that watch.
Anyway, this one works well as a replacement, I guess. I'll always miss some things like the fun animations (which I'll never get on the Garmin), or the 2-week calendar on the watch face (which might be possible on the Garmin but I can't figure that out). I don't really need to know my blood oxygen level, or track my runs down to the second, or get a nightly sleep score and a daily morning report, but this watch does all those things.
It doesn't look as nice as my pebble, but the screen is bigger. It also doesn't have a microphone, the most underrated feature. Actually, that would be Timeline.
Anyway, I miss you, PTS, and don't lose hope. Maybe I'll have it in me some day to replace your battery. Please forgive me.

5.0 out of 5 stars Perfect for what i need and more
Reviewed in the United States on May 26, 2024
This watch is great for running and cycling (i have not swim with it yet bit im sure it will perform as intended). It fits great on my wrist and it is confortable, considering I have skinny wrist. I enjoy the stats and data it provides, specially the workout suggestions. I was not interested on the workout suggestions, however i did noticed that its recommendations are based on your saved work outs. The battery seems to last a considerable amount of time i have charged it once per week(i run 3-4 times a week for at least 40 minutes with the gps on). Lastly, it charges quickly, i would say an hour and a half to reach full charge.

5.0 out of 5 stars Avid Runner Loves This!
Reviewed in the United States on June 30, 2024
My husband bought this after his Apple Watch, since it is more exercise focused. He has loved it thus far. The distance on his runs is much more accurate, it is waterproof, has sleeping insights, and battery lasts a long time! I still need some convincing to move from my Apple Watch, but for the regular exerciser, this watch is great!
