  • Well Worth the Money
Color: Black Size: 46 MM Style: Music Pattern Name: Smartwatch
I LOVE this watch. I've been debating buying a running watch for so many years now and finally decided to do it. I have been doing marathon training and this watch has aided me plentifully. It has cool features when you record runs where it'll tell you every time you finish a "lap" which you can set the distance for - so during a long 10 mile run I have it set to tell me every time I finish 1 mile and what pace I finished it at. It also has cool badges you unlock when you run certain distances, and it will notify you every time you recorded a new personal best mile, 5k, 10k, half marathon, etc. during any long run. It displays a very accurate heartrate as well which I've tested multiple times and it's always within 5 of what I measure manually. You have to download Garmin Connect and Garmin Connect IQ on your phone which can then be used to download your favorite music app right to your watch (I use Spotify). From there, you can download your music/playlists/podcasts/audiobooks right to your watch. You can leave your phone at home then for long runs and just have your watch and your headphones with you; which is a lifesaver personally lol. The second you get back home from a run, it'll connect back to your phone and send the data over immediately. On your phone you can then see all your runs, as well as the pace, average heartrate, calories burned, and a few other cool measures. It can also record your sleep and give feedback on the quality of it, length, etc. but I have yet to use this feature. I sleep like a rock and can easily tell how well I slept when I wake up haha. I highly recommend this product. If you are on the fence as I was for so long, GET IT ... show more

  • Does everything I need
Color: Black Size: 46 MM Style: Music Pattern Name: Smartwatch
Fully charged lasts about 2 weeks depending on how many activities you use. I'm not super techie so it works for everything I need. Tracks workouts, body stats, sleep and manages notifications/ alarms on my phone . Literally all I need it for besides of course telling the time. Good, affordable forerunner. If you want a super advanced watch with a million features, though, this may not be the one for you. ... show more

  • Long battery life, Scratch resistant
Color: Black Size: 46 MM Style: Music Pattern Name: Smartwatch
Very high quality watch, I love how I can use it while swimming and not worry about getting it wet. The battery life is amazing and I had some moments where I thought I might have scratched it, but the screen is very durable and scratch resistant.

  • Insane amount of tech for $250
Color: Black Size: 46 MM Style: Music Pattern Name: Smartwatch
It’s hard to believe everything that this watch can do. I’m amazed at the tech packed into a watch this size, with a battery that lasts 2 weeks. This thing tracks sleep, all kinds of activities, performance and health stats, and more with high accuracy. It can even do navigation - I actually loaded in the course for a 50 mi ultramarathon a month ago and this watch saved me when I missed a turn. It’s lightweight, durable, and waterproof - I shower in it, run/ride in the rain, ride off-road, etc. and it barely shows any wear. I’m sure a direct hit to the screen would damage the watch, but they do sell screen protectors. I’m a 180lb male and it is the perfect size for my wrist. It looks great, not too big. Pairing is easy, but learning the buttons does take some time. After a month of using it feels intuitive now - just be patient. You are controlling a full on computer with 5 buttons. For me, this watch does everything I want and more at a very reasonable price. ... show more

  • Awesome watch! 💚

Love this watch, it is exactly what I needed. It really helps monitor how stressed my body is and also tracks strength training. I’m also using it to train for a 5k. 😁

  • Great training tool for runners.
Color: Black Size: 46 MM Style: Music Pattern Name: Smartwatch
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. ... show more
