Garmin Enduro 4 Leaked: First Details Emerge
Correction (17 June 2026): An earlier version of this article stated that the Enduro 3 was built on the Fenix 7X platform. It is built on the Fenix 7X Pro hardware platform, with the Fenix 8 software platform on top. The feature list has been updated accordingly. Thanks to readers Pecio, DanMcz and Brian Reiter for the correction.
Gadgets & Wearables has confirmed this site’s findings in the latest Garmin Connect app, which mentions the Garmin Enduro 4. Here is what that likely means, based on what we know of the Garmin range.
What the Enduro range is
The Enduro is Garmin’s answer to one question: how long can a GPS watch last? The current Garmin Enduro 3 lasts over 30 days in standard GPS mode, and even longer with solar charging. It uses a traditional low-power MIP screen rather than the bright AMOLED displays now standard on the Fenix range. That screen technology draws far less power and allows solar cells to be included. The result is a watch built for ultra-distance running, multi-day mountain routes and anyone who cannot charge every few days.
Although internally categorised as a running watch in the Fitness division, think of it as a Fenix with the battery turned up to maximum.
When to expect it
Since the Enduro 2, Garmin has followed a roughly two-year refresh cycle: Enduro 2 in August 2022, Enduro 3 in August 2024. An August 2026 launch would fit that pattern and is likely, given the nature of the leak. Specific device mentions in the Garmin Connect code usually indicate a release is close.
What it is likely to cost
Garmin’s Enduro pricing has tracked the equivalent Fenix model:
| Watch | Launch Price | Equivalent Fenix | Fenix Launch Price | Gap |
|---|---|---|---|---|
| Enduro 2 (2022) | $1,099 | Fenix 7X Sapphire Solar 51mm | $999 | Enduro $100 more |
| Enduro 3 (2024) | $899 | Fenix 7X Pro Sapphire Solar 51mm | ||
| Enduro 4 (2026?) | TBC | None (no MIP solar Fenix 8 Pro) |
The Enduro 3 broke from the Enduro 2 premium and came in below the equivalent Fenix for the first time. The Fenix 8 Pro is offered only in AMOLED and MicroLED, with no MIP solar variant, so there is no direct comparator to anchor an Enduro 4 price.
What is likely to be new
The most probable addition is off-grid satellite messaging. Garmin added this to the Fenix 8 Pro last year, enabling two-way text communication without a phone signal. The Enduro is fundamentally an off-grid watch, and the absence of that feature from Enduro 3 was already a gap. It is the obvious upgrade for a watch bought by people who spend days beyond mobile coverage.
Solar charging will almost certainly return. A screen change to AMOLED would undermine the watch’s core battery advantage, so that seems unlikely.
The Enduro 4 will likely be built on the Fenix 8 Pro hardware platform, much like the Enduro 3, which was built on the Fenix 7X Pro hardware platform with the Fenix 8 software platform on top. For anyone upgrading from an Enduro 3, that is a two-generation jump in hardware. The Fenix 8 added features the Enduro 3 never received:
- Built-in microphone and speaker, for phone calls and a voice assistant from the wrist
- Dive capability to 40 metres, with full EN13319 certification
The Fenix 8 Pro then added the comms hardware that matters most for an off-grid watch:
- LTE connectivity
- Two-way satellite messaging via inReach, the likely headline addition for Enduro 4

Quick answers
What is the Garmin Enduro 4?
The Garmin Enduro 4 is the next generation of Garmin’s ultra-endurance GPS watch, designed for long-distance running and multi-day adventures where battery life is the priority. It has not been officially announced. The name appeared in a teardown of the Garmin Connect app in June 2026.
When will the Garmin Enduro 4 be released?
Garmin has not confirmed a release date. Based on the roughly two-year refresh cycle, August or September 2026 is the most likely window.
How much will the Garmin Enduro 4 cost?
Garmin has not confirmed pricing. The Fenix 8 Pro is offered only in AMOLED and MicroLED, with no MIP solar variant, so there is no direct comparator to anchor a price for a MIP solar Enduro 4.
Will the Garmin Enduro 4 have satellite messaging?
Nothing has been confirmed. However, Garmin added satellite messaging to the Fenix 8 Pro in 2025, and the Enduro is positioned as an off-grid watch. It is a reasonable expectation for the new model.

Any chance for a 47 mm version do you think?
probably the fenix
The Enduro 3 is built on the Fenix 8 platform and has an ECG. There’s an error in the description.
exactly, thanks
As Pecio already mentioned, all the predictions in the post are flawed because of that single fact: the Enduro 3 was already a Fenix 8 based watch. Thus, the 4 is much more likely to be a Fenix 9 based device, or possibly an 8 Pro based one, though I don’t think they would do that.
It also seems possible, that they will completely omit the Fenix Solar line and make the Enduro in different sizes (which I would be really happy about, not everyone want Amoled, who has a small wrist)
Your table is slightly off. The enduro 2 was a fenix 7X with a larger battery. The enduro 3 is based on a fenix 8 solar, not a 7X. The enduro 4 would be a hypothetical derivative of a Fenix 9 51mm with a MIP display. (The original enduro was a more modified derivative of a Fenix 6X.)
Although I know a couple of people who have a Fenix 8 solar 51mm, I think this was entirely because of what the Garmin agent chose to import into their country onto the local market and they would have been just as happy or happier with an enduro 3, given the option. I would not bet on there being a Fenix 9 offered with a MIP display. I think they may reserve that for a SKU of the tactix and enduro.
I do expect Garmin to move from LTPS to LTPO amoled displays to get native 1hz refresh capability and more power efficiency. (This is one of the reasons the Suunto Race 2 and Vertical 2 are so competitive with battery range against a Fenix 8.) Also possibly making the displays incrementally larger to 1.5” and shrinking the bezel area. And also I would expect them to finally update the SoC to the NXP RT700 series.
Correction made. My understanding is a Fenix 7X Pro hardware base with the Fenix 8 software layer. Bottom line: the off-grid comms must surely be on the E4, and that requires the Fenix 8 Pro hardware.
As you say I guess it’s pretty much semantics. The only difference between the 7 pro and 8 is buttons, speakers, depth sensor and software. The f970 is even less different — it’s just the flashlight, speaker, and software.
I agree with Brian’s assessment IRT MIP displays. I would venture to say Enduro and maybe Tactix will keep MIP, the rest goes AMOLED. Since we don’t know how popular MIP actually is, it’s difficult to say if there is an economical reason to produce a 47mm version. My guess is no, there isn’t. Most people I know prefer the shiny AMOLED. I own the Tactix 8 Solar and AMOLED (and the Enduro 3…I know, kinda excessive…) and I alternate between the watches. But in the summer, I prefer MIP any day of the week.
There’s almost no way we’ll see a Fenix 9 based Enduro before we see the Fenix 9.
Then again, it almost makes no sense to release a 8 Pro based Enduro so close to the release of the Fenix 9 which is supposed to have an integrated antenna and a much lower profile.
agreed
where is that f9 info from? and what do you mean by integrated antenna please (they’re integrated now in one sense) ty!
other than MARQ, enduro is the last hardware iteration of its current hardware base. i think the confusion last time was that it was so late that it got the new software
lets say enduro (guess) came out next week. a F9 in sep/oct would work from garmin’s POV.
They better change their satellite messaging before add it tot the enduro. It it does not work well and the lte service is limited
Agreed!
Easier said than done!
E3 vs E2: Solar panel was removed above the area where data are shown in the display.
E4 vs E3: Offering either Gorilla Glass or inventing anything to diminish the adverse (darkening) effect of Sapphire on the display would be my only desire from E4.
Temporalily I used my son’s F5plus when I had neither an Enduro nor an Enduro 2 with me, and I liked so much the real black and white display. The grayish or brownish display of Enduros are such a pity!
Everybody said about Enduro 1 and 2 that Solar was more important than anything, but later Garmin sacrificed some of the real (!) battery life coming from the full display size solar panel. Still now everybody says that a rugged Enduro should have a sapphire to protect the display, but I still believe there is another way than having either a backlight or an amoled to get back the contrast of earlier MIP displays.
I wrote a long comment which has been eaten by the “post comment engine”.
Repeating only the main message: I believe finally there will be an Enduro generation either without Sapphire or with a modified Sapphire to get back the clear visibility of Fenix 5 plus or Fenix 6. Solar panel as an obstacle to achieve it was removed (see E3 vs E2), it is high time to solve the other obstacle.
Test.
My comment on another article appeared immediately, but here I cannot comment it (no links at all). Now I shortened my comment.
i cant see any email that sin’t published.
it should publish immediately
only if there are two or more url/links might there be a problem.
Strange, but in the meantime I explored reddit sailing with Pinta. 🙂
My understanding is that MIP is more expensive than AMOLED at this point for Garmin and the panel is thicker. The display has significantly lower resolution and color depth. This allows a larger battery in AMOLED units which partially offsets the energy difference. Garmin doesn’t even have the “good” AMOLED LTPO which is more energy efficient by being able to have a variable refresh rate. In most scenarios the AMOLED is no worse or significantly better than MIP at the job of displaying information clearly depending on the conditions.
There are also chip improvements that could save a ton of energy with reduced process size and vector display process instructions to reduce the overhead of map rendering calculations.
Although there are some vocal proponents, I think MIP is increasingly niche. That’s why smaller manufacturers like Suunto are just totally eliminating MIP with LTPO and getting equivalent battery life in the Vertical 2. Garmin has a lot of head room in chip and AMOLED technology to improve performance and range.
agreed.
I doubt there will be much hardware that garmin shows for the first time on Enduro.
as you indicate there are a few areas to improve battery life, which is a key differentiator for Enduro.
perhaps there will be one thing that offsets the satellite/LTE feature
> In most scenarios the AMOLED is no worse or significantly better than MIP at the job of displaying information clearly depending on the conditions
Except when you’re talking about using the watch as a cycling computer where you can’t simply flick the wrist to see the metrics. When mounted on a bar, the watch will need to be burning at full brightness for the entire trip, so it’s a no go for me in that regard. I dont want to buy a separate bike computer. Plus, I simply hate the aesthetics of Amoled.
fair case exception.
