With rumours and leaks for the new Garmin Fenix 6 ramping up in the past week I thought it would be worth comparing what we know or suspect will feature in the new Fenix models in comparison to the closest Garmin rivals, the last generation Fenix 5 Plus, and the most recent Forerunner 945.

News of the Garmin Fenix 6 started last Sunday following a YouTube leak of some renders. At the time they looked a bit questionable, but since they takedown notices have been issued, then photos of the Fenix 6X Pro leaked, and an Amazon listing for the Fenix 6X Sapphire briefly appeared.

As no official information has been released about the Fenix 6, this is all speculation at the moment. I will update the post as more information comes in.

Fenix 6 Series Models

Assuming all the leaks are correct, there could be a range of new models that were not featured on the Fenix 5 series.

The product line-up includes:

  • Garmin Fēnix 6 / 6 Pro
  • Garmin Fēnix 6s / 6s Pro
  • Garmin Fēnix 6x Pro / 6x Pro Solar

The Amazon listing showed two 6X models, the 6X Sapphire and 6X Sapphire Solar. There was no mention of Pro models. The leaks didn’t indicate a non-pro 6x, this could be an omission, it is an odd or stupid naming scheme to have Pro models but then no standard model.

The current line-up has Sapphire models for each edition, so one theory (I have) could be that the Pro is supposed to be Sapphire.

Another guess could be that the Pro models might indicate something like LTE, but that is pure speculation on my part.

Design

From the three leaks, it appears that Garmin is keeping the basic design almost identical to the Fenix 5 Plus series. The Amazon listing does indicate that the 6X will have a 1.4” display up from 1.2” of the Fenix 5 series which should help with readability and improve aesthetics. It is believed that the Fenix 6 will have a 1.3″ and 6S a 1.2″ display. The result of this is a noticeable difference in screen real estate with the there being much less dead space of the newer 6X.

The images we have from the leaks are hardly exceptional, but there are no other dramatic design changes.

The screw features are in the same place with two screws near the activity button, then singular screws to the bottom right, bottom and top right.

The one design difference that I can see from the live images of the 6X Sapphire is the layout of the numbers and design around the dial. There is a white line indicator at 0,20,40,50mins and a triple red line at 10 mins. The current 5X Plus has a single red at 0 then number for the others. Not exactly a significant design change.

Obviously, in comparison to the FR945, the design is very different. The Fenix range is much more adaptable for casual use, I particularly love the Fenix 5S design. This does come at the cost of weight though, and the 5S weighs 64g while the FR945 weighs 50g. The 5X Plus then goes up to 96g.

Heart Rate Monitor

The Forerunner 945 is the watch that will closest resemble the Fenix 6 in features or the MARQ for rich people. So it is a given that the Fenix 6 will replicate all the features that the FR945 has.

This, therefore, means the watch will have at least been upgraded Elevate optical HRM sensor + Pulse Ox (SpO2).

One rumour is that an ECG might be included, there is not a great deal of evidence to back this, but it would help differentiate it from the FR945 and also bring it in line with features from Apple and Polar.

GPS

As with the FR945, it is expected that the Fenix will upgrade to a Sony GPS chipset which should result in lower battery drain.

Multiple satellite systems will also be supported (GPS, GLONASS, Galileo).

Maps

The 5 Plus series included full-colour TopoActive Europe mapping preloaded with map data optimized for at-a-glance navigation and location tracking, as did the FR945, so the Fenix 6 will have at least this.

FirstBeat Features

The table below shows a full feature list of the FR945 vs the current Fenix 5 and 5 Plus, I also threw in the Fenix 3 HR just to show how far things have come.

Just like the HRM, we will definitely see all these features replicated. Garmin has more FirstBeat features than any other brand on the market.

The Suunto 5, does, however, have 3 features the Garmin does not. Personalised training plans, sleep quality assessment and fitness age. Then the Polar ignite offers things like sleep score, nightly recharge, and fitspark, which provides training plans adapted from the quality of your sleep.

As the Fenix 6 is the flagship model for Garmin, I would put money on this introducing a few new FirstBeat features. Some form of sleep tracking improvements and maybe personalisation based on sleep makes a lot of sense to me.

PacePro

This is the one big feature coming out that we have a bit of information on. This was from the Amazon listing and was described as grade-adjusted pace guidance throughout your activity.

While I can’t confirm exactly what this, it sounds like an alternative to power. Your pace will change as you go up and down hills, but your power output/effort may remain constant (ideally). With PacePro this will give the reading in the form of a pace rather than watts. So this might be 7mins per mile on flat, then if you run 8 mins per mile on an x% gradient the PacePro will feedback you are running an equivalent of 7mins per mile.

Battery

At the moment, there is no information on battery life.

The current 5X Plus has 20 days in smartwatch mode and 13 hours in GPS, the leaked Solar images indicate 21 days, and assuming Solar means what everyone expects it to, then the Solar function adds around 5% to the battery life.

The original 5X had up to 12 days in smartwatch mode (depending on settings), up to 20 hours in GPS.

The Forerunner 945 has up to 2 weeks in smartwatch mode, 10 hours in GPS mode with music or up to 60 hours in UltraTrac mode

So it would be logical to assume that the battery life will go upwards. Though the trend for GPS battery life has been going downwards, I would hope this does not continue.

Display

Lots of rumours have suggested an improved display or maybe even AMOLED. The current leaks and images indicate no change. The display size is larger on both the 6X and 6 as previously mentioned. Now at 1.4” and 1.3” respectively vs 1.2” on the previous models.

The FR945 has a 240 x 240 pixels display at 30.4mm which matches the 5X and 5X plus.

Going up in resolution does seem like an obvious upgrade, but Garmin will be quite cautious about the effect this has on battery life.

Smart Features

Currently, there is nothing to indicate that the smart features will be any different. These will include NFC and music across the range, plus Wifi and Bluetooth connectivity.

The FR945 has safety and tracking features to make it easy to share your location with chosen contacts in case you need assistance. This includes built-in incident detection. So it is a given that the Fenix 6 will include this.

The 5 Plus series uses 16GB of storage. The FR945 doesn’t state the amount but lists Up to 1,000 songs. A memory upgrade is a possible option, though I don’t see the need, 16GB is a lot of music and maps. Though more storage is always handy.

Price & Release Date

Things are a little more confusing here. Until the Amazon leak, I would have bet good money that the Fenix 6 series will be announced at CES 2020 in January. This would have followed the same pattern as previous Fenix releases.

While I am still inclined to think CES is the most likely, the recent Amazon leak indicated this month! With a launch date of 29th of August 2019.

On one hand, this is possible, it is just in time for IFA in Berlin, on the other, it is very off to launch to public a few days before one of the worlds biggest tech shows. They would typically launch at it, with availability days or weeks after the show.

The Amazon leak indicated that the 6X Sapphire would be $949 while the Solar would be $1149. That sounds like crazy money, but these sit at the very top of the Fenix 6 Series. The current 5X Plus Sapphire sells for $1,049.99 on Garmin USA, so for them to drop the price by $100 is another odd move.

The current base model 5S Plus retails for $599.99, though it launched at $699, and the FR945 is also $599.99. So I would expect the cheapest Fenix 6 to launch at least $699.99 in order to avoid cannibalising the FR945 sales.
