Garmin Enduro 4: A $899 Solar Watch with 320-Hour Battery and Fenix 9 Software

Key points

• The Enduro 4 is priced at $899.99, matching the launch price of the previous Enduro 3, though the older model is currently discounted.
• It features a 51mm fiber-reinforced polymer case with a titanium bezel, weighing 66g, which is significantly lighter than the Fenix 9 Pro Solar.
• Hardware upgrades include a faster processor, 50% more RAM, and doubled storage to 64GB, enabling faster map rendering and a new perspective view.
• The watch retains the same 1.4-inch MIP display and solar charging capabilities as the Enduro 3, with battery claims of up to 90 days in smartwatch mode and 320 hours in extended GPS mode with solar.
• Software updates include Garmin Epic for multi-day events, new stamina zones, and improved rucking metrics, though some features are exclusive to the new hardware due to processing constraints.

Background

The Enduro 4 follows a pattern established with the Enduro 3 and Fenix 8, where the Enduro series serves as a lighter, cheaper, and more battery-efficient counterpart to the flagship Fenix line. Previous archive coverage noted that the Enduro 4 was launched to compete with the Apple Watch Ultra 4 on battery life while maintaining a lower price point. The release targets users who prioritize endurance and solar charging over connectivity features like LTE or satellite messaging, which are reserved for the higher-end Fenix 9 Pro models.

How outlets are covering it

DC Rainmaker emphasizes that the Enduro 4 is primarily an upgrade for Enduro 1 and 2 owners, as Enduro 3 users will receive most software updates for free. Ray Maker notes that while mapping speed improvements are noticeable, they are not dramatic in real-world usage, and the main value lies in the new software features and hardware efficiency. HiConsumption highlights the 'unlimited' battery potential in expedition mode with solar charging, framing the watch as a solution for users tired of daily charging routines. Gizmodo compares the Enduro 4 directly to the Apple Watch Ultra 4, noting that while the Apple watch has a brighter OLED display, the Garmin offers vastly superior battery life for outdoor activities. Freeyork focuses on the watch's utility for ultramarathons and remote treks, praising its durability and solar capabilities, while also noting the absence of premium materials like full titanium cases found in the Fenix 9 Pro.

Why it matters

The Enduro 4 reinforces Garmin's strategy of segmenting its market by offering a device that maximizes battery life and weight efficiency for extreme outdoor use. By sharing the Fenix 9 software platform, Garmin ensures that its budget-friendly line remains feature-relevant without compromising the core value proposition of the Enduro series: longevity. This move appeals to athletes and adventurers who prioritize reliability and solar charging over connectivity and premium aesthetics, potentially capturing a niche market that finds the Fenix 9 too heavy or expensive for their needs.

What to watch

Garmin plans to roll out most of the new software features to existing Enduro 3 and Fenix 8 users, though some hardware-dependent features like the new mapping engine and perspective view will remain exclusive to the Enduro 4 and Fenix 9 series. The timeline for these updates is not fully specified, but Garmin has indicated that not all features will arrive by the end of the year. Future releases may see further refinements to the MIP display technology or new solar charging efficiencies, though current industry trends suggest limited innovation in MIP panels due to declining unit volumes.
