FR735XT is the go-to device for triathletes – tracks everything you could ever need with the ability to connect an external HRM for improved dynamics.

Full color; backlit display; GPS; GLONASS and Ultra-Trac mode; 6-7 days of battery life; Daily alarms and move reminders

Durability concerns due to plastic casing; HR sensor is not great for dynamic movements; Music playback doesn't work very well

I wanted a GPS fitness watch that was also a smart watch not the other way around. It needed to have built in heart rate and activity tracking as well. This watch meets my goal of focusing primarily on fitness while also being water proof.

weights; "always on" feature; waterproof; audible and vibration notification; music control; long battery life; excellent value (on sale

special charge cord, losses Bluetooth connectivity, still expensive, not running the latest Garmin Connect SDK; No barometer, altimeter, or compass built in; Guess I'd need the crazy expensive Fenix 5 series for that

The Garmin Forerunner 735XT is meant for hard-core athletes, such as those into multi-sports such as triathlon and who are already logged into serious fitness regimes. This is one of the premium options for such athletes and provides complete analysis of their progress and endurance abilities.

Multi-sport watch; accurate monitoring; detailed analysis

Bland looks; little bulky

A full feature set for multisport athletes in an easy to wear design. The great battery life and support for smartwatch functions means you're fully informed whether that's on your daily activity or the specifics of your training.

Excellent HR and GPS performance; Lots of functions; Comfortable to wear; Compatible with a full range of sensors; Great for multisport athletes with specific profiles for triathlon and duathlon

No on-board music support; UI is a little convoluted; No altimeter/barometer for accurate elevation tracking

A great running and triathlon watch, with slim design, long battery life and now a much better price to go along with it. Although a little lightweight in nature it's more than good enough to function as a daily timepiece, and actually shows up some of the more 'dedicated' smartwatches.

Long battery life; Good smartwatch functionality; Accurate GPS

Plastic feel; Some fitness tracking could be better; Heart rate monitoring not great from wrist

I specifically chose this Garmin- as it was on the smaller, lighter side of things making me (I hoped) less aware of it when I was open water swimming. This it has been.

it 's a great product, but for me , i found it , to complicated, or some time confusing , to monitor, my activities, to many buttons to choose from , specially in multi sport, I would like to see better manual on the product,

I purchased this watch about a year ago and do moderate activity. About a week ago i noticed the screen had cracked & I know i did not do any sort of hard core activity to cause the screen to break or even hitting the screen on a hard surface.

great watch for tracking metrics and keeping you on track for fitness

I've just got this fitness watch so can't give it a full review yet. First impressions are good. The watch is super comfortable and light weight so you forget your even wearing it most of the time. The face is large enough to see everything it displays and has enough room to fit in all the features.
