Rated 5 out of 5 by from the lightest most functional multi-sport watch This is the latest Garmin multi-sport product and it is absolutely unbelievable. It is lighter than any Garmin I have owned in the past and at numerous times I wasn't even sure it was on. The functionality is the best of the Garmin watches. The acquisition of satellites is super fast. The integration with the Varia accessories is very welcome and works perfectly. The HR seems to be super accurate. I would highly recommend this to anyone looking to get a full functioning multi-sport watch and fitness tracker. I am a little concerned about the plastic face and how long it will remain clear and unscratched.

Rated 4 out of 5 by from Really impressed Have had for almost a month now and I really like this watch. Only reason it did not get 5 stars is because it does not have a "hike" mode and because I still think $450 is outrageous. Love the way it syncs with phone app. GPS and heart rate work very well. For those of you like me that want a watch for hiking and don't want to spend $600 for the can use this watch in "run" mode. Some of the metrics watch tracks in run mode will not be relevant, but it will still track your mileage, elevation, and time. Does excellent in bike mode as well.

Rated 5 out of 5 by from Goldilocks and the three watches For the last three years I've been using a Garmin 910XT, which got the job done admirably as a purely exercise specific device with almost no modern frills. I decided to try out a Fenix3, it seemed like exactly what this Army, outdoor enthusiast, fitness data oriented person wanted, but I could never stand the weight, especially for sleeping with it on, which negated the sleep tracking, and it just wasn't good enough for being $500+. The 735XT came in and does virtually everything right. the battery life is phenomenal, I get about 6 days including all workouts (but if you're an Ironman-er you might want to go with the Fenix3), it has all the features I need for biking, running, swimming, and hiking. An Altimeter would be nice but that's about all it's missing. The heart rate monitor works better than expected and it's weight is feather-light. The sync to my iPhone is nice

Rated 5 out of 5 by from FREAKING AWESOME! It's the only nice smart watch I've found you can actually swim with. Unless you send your Apple watch, Samsung, or Fitbit in to be water proofed, you can't swim or shower with them. This watch also having GPS is seems pretty limitless.

Rated 5 out of 5 by from Great for active people I love this watch. I had been debating between the Forerunner 235 and the Garmin Vivoactive HR when this was released. It has the best of both worlds. I generally run, hike, and lift weights. This tracks all of that. My girlfriend swims and it is great for that too. We constantly compare our steps with each other and how much sleep we are getting. If you like to be active, this is a must buy. Granted, this is no Apple Watch or Android Watch or whatever - it has very finite specific uses, though you can download a variety of face widgets to show you useful information. However, those fancy smart watches don't have the amazing battery life that this does. I can go over a week with regular exercise before recharging. That is one of the reasons I have stuck with it - I never have to take it off except for 30 minutes or so once a week. We have found a few quirks. Sometimes it takes a while to lock on to satellites before a run. It lacks a barometer, so no flights of stairs climbed (but really that's not a big deal to me - I just can't compete in that category against my brother who has the Vivoactive HR). It also randomly stopped tracking steps and froze once, but it hasn't since. The one weak spot is the app, however that is easily changed by Garmin. The website app is amazing. The iPhone app still does a lot, but is much more limited. I fully expect this to improve over time. Also, you need to either put the watch in sport mode or have the app open to get them to sync. Since I frequently use both this isn't a problem, but its not like someone you are "connected" with through the ecosystem can see a live value for how many steps you've taken in a day. Good thing is the app takes full advantage of Apple's HealthKit, so when I weigh myself on my Withings scale, Garmin knows what my weight is automatically. All and all, I would totally recommend this watch to someone else. It is worth every penny and looks good to boot.

Rated 5 out of 5 by from All around multitasking watch I received this as a Valentines present from my husband. He actually called my best friend and she told him what Garmin I wanted. I owned an old Garmin forerunner 410 for years, that completely quit working over the summer; however the Garmin 410 got me through, multiple ultra marathons, marathons, half marathons and everything in between. I decided that i wanted to upgrade to a Garmin that I could use competing in multi-sports. I LOVE this forerunnner 735. If you have ANY doubts, just buy it, it's worth it! I love the face it app, and I wear it everyday to work as it counts steps and records all day heart rate. Which is cool! The Garmin forerunner 735 is very easy to use, with an easy startup. The watch works as indicated on the treadmill , without a foot pod, and is spot on with heart rate and pace.

Rated 5 out of 5 by from Amazing GPS watch! This is the best watch I've ever owned. Had it for several months now and am still thrilled about this purchase. Great for workouts (even multisport workouts) and constant monitoring of activity, heart rate, and calories burned throughout the day. I had the Forerunner 235 before this watch and was disappointed with it. This one is well worth the upgrade.

Rated 4 out of 5 by from good watch I had a Fenix 3 that I really liked with the exception that it was a little bulky/heavy and that the exact time would drift slightly. I then tried the 920. I liked the fit, but the screen was a lot smaller than it looks like it should be and the screens/functionality are fairly limited. The 920 is a pure tri watch and I was looking for more everyday watch that could also serve as a backup to my cycling computer. The 735 is very light & comfortable. It has more functionality than the 920, but not as much as the Fenix. Overall I'm happy with this watch, but won't think twice about replacing it as the next cool thing comes out. The HR monitor is ok, but if you're really into knowing your HR, don't let this feature be a deciding factor in your purchase; you'll probably want a chest strap monitor anyway.

The 735XT has built-in HR Monitor... What is the use for the two separate monitors / straps ?

Asked by: aclement
The HRM Tri and HRM Swim straps included in the Forerunner 735XT bundle will give you additional metrics such as heart rate while swimming, cadence, stride length, ground contact time, ground contact time balance, vertical oscillation and vertical ratio.

What does the 735XT do different from the 235? I am looking at using it for training for a tri.

Asked by: JStreetWalker
The Forerunner 735XT is compatible with the new Tri and Swim-HRM straps from Garmin. These straps can give you beats per minute while swimming. The Forerunner 235 cannot is not compatible with these new straps.

Looking at replacing the 910XT with the 735XT or the Fenix 3hr. We have recently added in Kayak and hiking to our activities but only competitive in Tri's. Thoughts? I understand the fenix is a little more bulky and heavier.

Does this watch work for tracking elevation gains/loss and speed when road cycling?

Asked by: kjhurley
This watch has a satellite-based altimeter for tracking elevation. Also, you can measure speed with the addition of the Garmin Speed Sensor (purchased separately) using the following link:​

I currently have a Suunto T4D and I'm wondering if this will be a good replacement? I mainly use the suunto for the training effect so i'm not sure if the suffer score is equivalent to that or not. In what ways is it similar or different. Thanks!

Asked by: ImproveSelf
Suffer Score is a kind of analysis of your heart rate monitor data from Strava that is included on the Forerunner 735XT Heart Rate Monitor Watch​. It is not a training program and it does not provide suggested workouts like Training Effect.

One of the reviewers says the watch does not have an altimeter, but you list an altimeter in the specs. Who is right?

Asked by: susanv
The specs say "satellite based altimeter". That means it uses GPS to calculate altitude, unlike the Garmin Fenix 3 or FR920XT, which both include a barometer that uses air pressure to determine altitude. They also both have a magnetic compass, which the 735xt lacks. Those are the two primary feature differences between this watch and the Fenix 3 HR. Supposedly the GPS-based altimeter and compass on the 735xt are fairly accurate in their own right, but be aware you don't get the dedicated components like you do in the Fenix. The tradeoff is you get a way smaller form factor in the 735xt, and half the weight of the Fenix 3 HR, but you lose the magnetic compass, barometer, and some battery life.

Do you have to wear a chest strap for the swim feature? Will the HR work in water with out a chest strap? Is this touchscreen?

Asked by: Kwald
To get a heart rate reading in the water, the Garmin HRM-swim or HRM-tri monitor is needed. The Forerunner 735XT is does not have a touch screen.
