Huge Fan

As a fitness tracking watch this is an awesome introduction to the Garmin platform. We are a Garmin and Apple family with four Garmins and two Apple Watches. I use this Garmin for walking, running, cycling, stretching and general workouts. I’m very happy with this watch and the data it provides.As I said I can compare this watch to several others. Let’s start with battery life. Our Apples are on the charger every night. The Garmins all go at least a week, I average 9 days. We also have an Instinct, a 965, and a Golf. Biggest “complaint” is forgetting to charge them.My 255 connects to my Apple iPhone 15 without issue. It also connects seamlessly with my MacBook Pro, zero issues. I have and use separate HRM’s because for intense workouts I don’t think a wrist based HRM is the answer. My chest strap is much better than my watch for workouts. The 965 however is much more accurate during runs (compared against arm strap HRM) so Garmin maybe uses different HR sensors in different models? For walking and general use during the day my 255 works great!Value for $… I’d strongly recommend this watch without hesitation if you’re thinking about entering the fitness watch/smart watch world.I entered this fitness data world because of age. I have a friend who is alive because of data changes he noticed in his heart during exercise. A triple bypass later and this fit cyclist is still riding with me. At 60+ I thought this data was for younger more aggressive athletes. Not so. I am now a data nerd and train regularly partly because of it.Didn’t think it was important, in honesty didn’t know it was a thing but I now am aware of HRV, FTP, Training Status, Sleep tracking, and Watts. It’s addictive. But knowledge is power and knowledge can be healthy. I owe a 25 pound weight loss to this knowledge (and a lot of work). This watch alone won’t cause weight loss but for me it was a part of the puzzle.I really like my Garmin Forerunner 255. That said, my next one will probably be a 965, but at the price difference I’m not 100% sure the difference is justified, certainly not if this is your intro to the data! The reason I will likely “upgrade” is simply because my daughter has the 965 and I want to be able to share that (cool, we both have the same watch) with her 😉Final thought as I wrap up this review, as I said I’m getting older and as such my near vision isn’t great without readers but I can actually see the time on this watch so.. there’s that.

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.

Great Sports Watch

I started to take my fitness seriously and bought this watch mainly to track my swims and collect data. I chose the forerunner because had enough functionality to expand into other sports such as running and cycling. So far it has been extremely accurate in terms of counting laps, stroke count etc. I has only been off once by one lane and I swim about 3 times a week. And I haven't tried out the other sports functions.The band is nice and doesn't chaff, the 46mm size faces isn't too big on me, even though I have pretty small wrist for a dude. And the battery life is great. I went two weeks without charging the thing. I have been pretty happy with it and don't regret my purchase. My only complaint is the screen is pretty dim even when it is lit up. Though if you have a bigger budget I would recommend getting an upgraded model for a better screen. It is totally workable, but you get what you pay for.
