The Garmin Fenix range has been an outstanding line-up of outdoor adventure watches since they were first released. You can trust Garmin to innovate and improve on an already successful product and that’s precisely what they’ve done here with the Garmin Fenix 3 Sapphire HR. Garmin have taken the previous Fenix 3, popped in a robust sapphire crystal display.
They have also added Garmin Elevate OFF the WRIST heart rate sensors and given it some great new strap styles and added 3 new sports profiles > golf, stand up paddleboarding & rowing. On top of that they’ve included the latest advanced running dynamics and physiological measurements and even.

Who’s it For?
Just like the rest of the Garmin Fenix range the Fenix 3 is aimed at people that don’t want to compromise in any aspect of their training. It’s got all the essential performance monitoring metrics of the Forerunner 630, the swim metrics and multisport triathlon functionality of the 920XT / 735XT …. it’s also a competent GPS navigation tool and 24/7 activity tracker with off the wrist (Garmin Elevate) heart rate monitor.
I’ll be quite frank here and say if budget is not an issue and you’ve been considering any of the following, Forerunner 735XT, Forerunner 630, Forerunner 235 or any previous incarnations of Garmin Fenix, bit the bullet and get this model. It looks great, it’s got outstanding battery life (up to 16 hours in GPS mode) and, to top it all, it comes with a sapphire crystal watch glass to keep it looking pretty for years to come.

TracBack feature navigates you back to your starting point the same way you came. Its built-in sensors provide information on heading, elevation and weather changes
Barometric Pressure sensor
The built-in altimeter provides elevation data to accurately monitor ascent and descent, while the barometer can be used to predict weather changes by showing short-term trends in air pressure. The 3-axis electronic compass keeps your bearing whether you’re moving or not.

Next Model Up
This is the top of the range with built-in Garmin Elevate heart rate sensors. If you want something even more exclusive and you’re happy to drop the off the wrist HR then it has to be the Garmin Fenix 3 Chrono. In January 2017 Garmin released the Fenix 5 (no Fenix 4, something to do with bad luck in Chinese). This latest incarnation has everything this model does plus it’s available in 3 sizes. A regular size, the Fenix 5, a small Fenix 5S and a LARGE one with more advanced mapping ability, the Fenix 5X.
Garmin Fenix 5 available in 3 different sizes – all versions with wrist based HR
Garmin Fenix Chronos (shopping partners website – approx £900 – £1000)
Alternative Garmin for Elite athletes
In May 2017 Garmin released the Forerunner 935. The Garmin Forerunner 935 aimed at elite athletes in all disciplines including Triathlon provides some of the very best training feedback with Training Load, Training Effect (aerobic and anaerobic) and Training Status. The 935 features a barometric pressure sensor but lacks some of the navigational features found on the Fenix range (e.g. route follow)
Garmin Forerunner 935 the best all round GPS sports watch for those not interested in GPX route navigation
Next Model Down
The next model down is the same watch, the Fenix 3, without the built-in HR. Personally, if I was spending this much money I’d get THIS ONE. However, if there some great deals on the regular chest strap version then go for it.
Garmin Fenix 3 without Garmin Elevate off the wrist heart rate.
It’s difficult to recommend a direct alternative to the Garmin Fenix 3 as it depends on the features / functions that attracted you to it. Watches that come closest to the Fenix 3 are the Suunto Spartan range of GPS sports watches. If it’s primarily for sports use and your racing time is under 9 hours then there is the Spartan Sport Wrist HR – also with wrist based heart rate For those looking for a fully featured ABC outdoor adventure racing watch it would have to be the Spartan Sport Ultra (currently not available with wrist based HR, but I am certain coming very soon ….) [April 2017]
Suunto Spartan Sport best suited to triathletes and other multisport exercisers – this version requires a chest strap
Spartan Sport Wrist HR best suited to triathletes and other multisport exercisers – also features off the wrist heart rate
Suunto Spartan Ultra best suited to outdoor adventure racers and ultra marathon / Ironman – chest strap required
Love them or hate them, smartphone notification alerts can be very useful. The Fenix 3 will alert you to incoming calls, texts etc.
5 x Heart Rate Training Zones
The Fenix 3 HR is a great sports watch for anyone involved in serious heart rate training. With 5 x auto-set heart rate training zones see at a glance which zone you are in. Your training zones can be personalised if you want to set them yourself. If you’ve not used a heart rate monitor before please try our heart rate zone calculator to get an idea of your own training zones. The clear colour coded heart rate display of the Fenix 3 HR also makes it a great watch for HiiT training.
24/7 Heart Rate Monitoring
Like the Forerunner 235 and Vivoactive HR the Fenix 3 HR samples your heart rate every 4 minutes (approx). Get a clear view of your peaks and troughs throughout the day. As well as this 4 hour view it is also possible to recall a 7 day HRH graph. This graph shows your daily average resting heart rate. Periods of extended elevated heart rate could be an indication of over exertion, illness or over training.
Daily Activity Tracking and Move Alerts
The RED bar is the MOVE BAR. Try to keep this unlit. After 1 hour of total inactivity the large lower bar fills. Following that, every 15 minutes the upper small sections will also turn red. When the whole bar is RED you’ve not moved for 2 hours ! The vertical bar on the left is your progress towards your daily activity target.
Videos (Garmin’s own)
Garmin say “True performance meets true style. Introducing fēnix 3 HR. The rugged, capable and smart multisport training GPS watch with wrist-based heart rate. Let the journey begin…..”
I prefer this video demonstration for a proper idea of what the Fenix 3 HR can actually do ..
And this one gives some good examples of Heart Rate related screen views …
