Garmin Fenix 5 – hardware specs leaked



(Edit: Jan 2017 – 5x specs here)

As half-expected <here> it seems that the FENIX CHRONOS really *IS* the hardware for the upcoming Garmin Fenix 4 following the latest leak, this time through appelmoessite.

If you think about it, it makes sense.

This could mean a Fenix 5 at CES on 5Jan2017, and almost certainly Q1.2017. The same source also suggests a diving watch variant on the F5 will be released before the F5 and called DESCENT.

Here is what we believe on the F5 along with some inferences and thoughts:

  • There are at least two versions including a more expensive STEEL version. Expect similar form factors to emerge inline with what we have on the Fenix 3.
  • New EXO antennae as discussed <here>. A hopeful GPS accuracy boost but the antennae is only part of the story when it comes to GPS accuracy other improvements will come from redesigned componentry inside the watch for example to include shielding and avoiding contact with other inner modules.
  • Optical HR Sensor changes
    • Component thickness reduced
    • Same ELEVATE sensor as used on the 735XT
    • Different sensor orientation compared to Fenix3 and 735XT
  • Reduced battery
    • Smaller size
    • Lower life at 180mAh (as CHRONOS) compared to previously at 290/300mAh. This unit taken from the Garmin 630 and so COULD deliver 13-16 hours of in-exercise use.
  • Casing
    • Maintenance access via screws on the rear, not front (like CHRONOS)
    • Thickness of the unit reduced due to smaller oHR and battery
  • New Barometric altimeter module
  • New 64 colour display (RGB22) which was previously 16 colours. Presumably increased resolution, although the CHRONOS is only 218x218px like the F3. More colours sounds great but IMO better resolution is still required to make it look like a ‘watch with proper hands’…even more than on the SPARTAN (320x300px)
  • Faster and more capable processor to support CIQ2.1 apps.
  • New Comms antennae for Bluetooth LE and ANT+. Unsure if this contains wifi capabilities for the F4.


Perhaps we can look at the CHRONOS now in a different light 🙂


BATTERY: Please do not get carried away with the thought that the Fenix 4 will have a greatly reduced battery life. It might. But don’t forget that Suunto, a much lower-resourced company, has still managed to release two versions of the SPARTAN where the main physical difference is the battery size and battery life – of course Gamrin are QUITE ABLE to do something similar.

So what this means is that if you want a Fenix 4 you can, SORT OF, buy one NOW. Just get a FENIX CHRONOS model. It’s HIGHLY likely that firmware upgrades will make it into a Fenix 4. So it looks like we all got the CHRONOS wrong. It’s not just an expensive F3.

The leaking of this news may come as no surprise. On the Garmin forums I only noted one comment from a CHRONOS owner on the FENIX 3 sub-forum (Chronos does not have a sub-forum of its own…yet). Not too many have sold I would imagine. This revelation MAY WELL boost CHRONOS SALES over Christmas from early adopters.

NOTE: This could simply be a hoax and/or a re-hash of the CHRONOS spec. Please note that I don’t just put stuff up here for click-bait …… because I want you to come back! If I think it is a hoax I won’t put it up. ie I believe this one is correct. Of course I could be wrong.

Here are some existing CHRONOS Features:

11 thoughts on “Garmin Fenix 5 – hardware specs leaked

      1. That would be nice. Options are good. Although it matters less for me now, I just ordered the limited edition copper Spartan Ultra. Just going to roll with the punches as it continues to get better via firmware updates. They seem pretty committed to eventually getting it where it should be. For some reason I’m just more into Suunto than Garmin. Perhaps I just like the underdog, haha.

      2. copper…ooooh. fancy! ye I like the ultra a lot but it is not quite there yet. come xmas/January it will be ok for my needs. it doesn’t seem to get a gps lock properly…make sure you sync before you use it that seems to help gps accuracy (if accuracy bothers you)

    1. Two different models would be nice. I personally would be OK with charging the watch a bit more often in exchange for less bulk/weight.

  1. let’s not forget on the feature list: a new charging connector, after changing it over past 12 months 9x times it get’s time to introduce something new Garmin!

  2. guys, is it worth it to buy now the discounted F3 HR, 450$ at Best Buy or to wait for F4 and decide after ? I presume that the offer for a lower priced F3 will continue.

    1. F3 will only get cheaper. Garmin are unable to release new products that do not have bugs. F5 maybe bug fixed by summer? if you need one sooner then buy now! buy it slightly cheaper on amazon here helps give me a small %age to keep the blog going 🙂

      1. Oh, thx man for the quick reply. I need it before summer, for sure. I will gladly use your link, ofc. Still not decided yet, my main question is how good/bad is the accuracy of the inbuilt HR sensor of F3 and how much it will improve in the F4 ? Nobody can answer now but you are already familiar with the F3 sensor, so how is it ? Thx again for you help.

      2. it will likely be the same oHR sensor version as the 735Xt and chronos. elevate “v2”. implementation into F5 may cause better or worse accuracy of course. flagship product so will eventually be good. ohr will not be as accurate as a chest strap and there are ohr variations from person to person and from sport to sport. if you are happy with some inaccuracy it will likely be fine.
