Fitness is the new obsession that many hardware manufacturers wish to capitalise on with from wearables for counting steps and measuring sleep to watches meant for hardcore marathon runners.

I had this watch for 2 years. It was working generally fine for running although it stopped paring with HRM run monitor strap after one year. Then it died after swimming in a pool a few times. The screen went black and could not be restored. According to other reviews, this is not uncommon.

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.

The Garmin Forerunner 735XT is a hardcore fitness tracker designed for triathletes and those who become excited by the prospect of a Tough Mudder challenge. It can be bought as a standalone unit (￡360) or as a Tri Bundle (￡450), which includes Garmin's advanced HRM Tri and HRM Swim chest straps.

Robust design; Great multi-sport support; Good coaching and activity tracking

App is difficult to navigate; Not the best-looking watch around

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.

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,

The best Garmin GPS I have used , super quick satellite finder , has all the features you will ever need and then some , I wear it all the time as a watch and personal activity tracker, press a couple of buttons and your into a run , cycle or swim .

This is a powerful training watch. However the design is very small for my usage. I would stay with the more expensive Fenix 3 HR over this one. You can also consider Polar m400 or Polar v800.
