The Garmin Enduro 4 was a no-show at the Fenix 9 launch — but a fresh leak suggests the mega-battery smartwatch could be imminent

• The Garmin Enduro 4 might have appeared in a new leak
• Details emerged in Indonesian regulatory filings
• The device might arrive before the end of 2026

We’ve barely had time to catch our breath after the Garmin Fenix 9 and Fenix 9 Pro announcement, but here comes news of another high-end Garmin watch looming over the horizon. Only this time, it’s not an official announcement that has shone a light on the device, but instead an intriguing leak that Garmin would probably rather you didn’t see.

The leak in question first appeared in regulatory filings from Indonesia (via Garmin News). There, listings mentioned an unnamed Garmin device bearing the model number A05197 in the “Outdoor Product” category.

Other details are pretty thin on the ground, but there is reason to believe it could point towards the unreleased Enduro 4. For one thing, Garmin News reports that Garmin uses the Outdoor Product category for “almost all of its high-end multisport smartwatches during testing phases, including past Fenix, Tactix, and Enduro generations.” That could therefore be an indicator that this mystery device belongs to one of those product families.

Then there’s the issue of previously leaked code references. We’ve already seen mention of the Enduro 4 in code contained within the Garmin Connect app, suggesting that the wearable is in development at the very least. Combine that with the new Indonesian regulatory filings and an Enduro 4 launch is looking increasingly likely.

A battery champ

Prior to the Fenix 9 Pro announcement, we had hopes that the Enduro 4 would also appear at Garmin’s launch event. That never came to pass, but it hasn’t dampened our expectations that the device exists and is on the way.

Interestingly, the unnamed Garmin device was granted regulatory approval in Indonesia on August 25 — the same day as the Fenix 9 event. Garmin News notes that it can take one to three months for a Garmin device to be unveiled after it is approved, suggesting that we could see the Enduro 4 — or whatever this unknown wearable is — before the end of 2026.

If and when that happens, it should be good news for fans of the best Garmin watches who want a device with phenomenal battery life. After all, as our Garmin Enduro 3 review noted, this line of watches “puts battery first.” We can expect the Enduro 4 to continue that tradition.
