Rated 5 out of 5 by from Loving It I have had the watch and HRM bundle for about 2 weeks and have been very happy with it. You don't need the strap for heart rate monitoring, the watch does have a heart rate monitor that works very well, but the strap adds dimension to your run, including VO2MAX, elevation, and several running dynamics. The watch is an activity tracker that will track your steps, sleep (automatically), heart rate, and syncs to apps like MyFitnessPal. I have used it for running both outside and indoors. It is the most accurate treadmill watch I have seen. I am continuing to learn what this watch can do and look forward to track other sports.

Rated 5 out of 5 by from I'm obsessed with this toy I finally decided to upgrade my old Garmin Forerunner, which felt like having a computer on my wrist every time I ran. I recently bought the Forerunner 735XT for Ironman triathlon training. After several weeks, I'm obsessed! The features are everything I need without too much extra size or bulk. The workout tracking and integration with my iPhone and apps (Training Peaks, My Fitness Pal, etc) is seamless. Sometimes the indoor swim distances are a bit off, but the tracking seems to catch up after a bit. If you're looking to do some multi-sport training, this watch is a great investment.

Rated 5 out of 5 by from Fantastic Watch As an avid runner who is getting more into biking and swimming but wanted basic smart notification and battery life this Watch is absolutely perfect. I recently purchased an Apple Watch but decided to get this and see how I liked it and it was the best decision I could have made.

Rated 2 out of 5 by from PoorGPS function drags this watch down Have used forerunner 405 before which had a much better GPS interface and performance. The 735xt is completely lost once you go near a tree or building. Ridiculously bad performance. Garmin put a cheap GPS in to save money? The HR function on wrist is silly. It's still recording HR when it's off. It's like this watch is OK with fake news. Very dissapointing. The sleep function is pretty good. It's not nearly bright or vivid enough. Dang. I wanted it to work

Rated 4 out of 5 by from Dependable GPS Device Solid GPS performance...good overall features, but wish it had WiFi and an altimeter. Also, the plastic makes the watch nice and light, but I'm concerned that it might not hold up over time--jury is out on this aspect.

Rated 5 out of 5 by from Exactly what I was looking for I bought the Forerunner 735XT a couple of weeks ago after about a year of researching (& putting it off because I wasn't finding what I wanted). So far, I love it. Awesome functionality and custom ability and super comfortable. My husband has the Sapphire and it was too big on me but I love how this watch looks and wears.

Rated 3 out of 5 by from Solid, but not MY daily driver This watch is perfectly functional and does everything I would want in a Tri-training watch. However, I was also looking for something that I could wear as a daily driver in an office type setting. I only purchased the black rubber band, but did not feel that the combo was something that I could "dress up" enough to be a daily. I am tall and skinny, but it still has a smaller face than I like. Further, the plastic casing gave me pause to have it on at all times. Now the good. I am a novice triathlete, but I am a fitness enthusiast and for those looking for something to track their training this watch is more than capable of providing the data you would want, and then some. If you are looking for an exclusive training watch, this is a solid choice. The metrics you get with the bundle are very helpful and WILL help you better yourself in the various disciplines, and the basic functions of an activity tracker are all there too. At the end of the day I could not get over the feel of the watch so I ended up exchanging the 735XT bundle for the Fenix 5 bundle.

One reviewer says this watch has no wifi--how does it connect? Does it have bluetooth? Also, specs for the 735 XT watch alone says it has a GPS altimeter while specs for the 735 XT run and tri bundles say atmosphere-based altimeter--which is correct?

Asked by: PJinNY
The Forerunner 735XT communicates wirelessly with other Garmin devices and sensors using ANT+ technology and can connect to your computer with the charging/dataclip. It does not have Bluetooth connectivity. The altimeter on this devices is GPS, not pressure based. Thank you for bringing the inaccuracies to our attention, we are having the information updated as soon as possible.​

Does the Garmin 735xt tri bundle include a charger? Mine came from REI without a charger, very little charge & a lot of old data. Seems really poor customer service not to have a charger included for the price.

Asked by: msultra
There should be a charging/data clip included. Please contact us at 800-426-4840.

I want to use the 735XT System for triathlon training and racing. Which one of the bundles do I need.I do have a footpos and a cadence sensor on my bike.  Ijust want to get the correct system for my objectives. Do i need the one strap or two strap system?

Asked by: 17 Hawkeye
This depends on the type of data that you are looking to gather. If you would like to know heart rate data after swimming, the Tri Bundle is the way to go. If you are just looking to get heart rate data while running and cycling, HRM-Run bundle is the best choice. The HRM-Run bundle does not give you heart rate data while swimming.

Is the Battery easily replaceable?

Asked by: Amish
The battery on the 735XT Heart Rate Monitor Watch is not user replaceable and should only be replaced by Garmin.

Confirm the 735XT syncs w/the Garmin bike cadence device, and operates in open water. Finally is the 'red' HRM strap any different in functionality than the "Tri-bundle" straps? Confirm that the watch cannot monitor course and locations like the 920XT.

Asked by: n1008
The Forerunner 735XT Heart Rate Monitor Watch is compatible with both speed and cadence sensors for cycling. The watch can be used for swimming both in the pool and in open water. The HRM-Run strap will only calculate running data (cadence, stride length, ground contact time, etc). The HRM-Tri calculates all of the running data and stores heart rate data when underwater, then forwards it to your wearable at the end of your swim. Both the 735 and the 920 will be able to monitor courses and locations.

Is the display always on during a workout? If not, how do you activate the screen? I am replacing a Series 1 Apple Watch and it takes too long for the screen to come on and then update current time, pace, etc after raising wrist.

Asked by: Brian
There are several backlight settings, so you can set up the screen in a few different ways. You can set up the screen to turn on with the press of a button or simply whenever you turn your wrist to face you.
