How to decide
Which watch actually achieves 'infinite' power?
The Garmin Enduro 3 and Instinct 3 Solar both claim unlimited battery life thanks to their solar charging capabilities. The Enduro 3 can stretch its smartwatch mode to an astounding 90 days with solar exposure, while the Instinct 3 also promises infinite battery life but requires consistent sunlight. In contrast, the Suunto Vertical 2 Titanium has a respectable 20-day battery life, but it can't match the solar efficiency of its competitors. For serious adventurers, the solar tech on these watches means you can focus on your activities without worrying about battery drain.
MIP vs AMOLED visibility in direct sunlight
When it comes to visibility, the Enduro 3 and Instinct 3 both utilize MIP technology, which excels in bright sunlight with their transflective displays. The Enduro 3's resolution is 280 x 280 pixels, offering clear visibility even under direct sunlight. On the other hand, the Suunto Vertical 2 Titanium shines with its 1.5-inch LTPO AMOLED display, boasting a brightness of up to 2000 nits, making it incredibly vibrant. However, while AMOLED displays are stunning indoors, they can consume more battery, making MIP a better choice for extended outdoor use.
Mapping capabilities on monochrome screens
The Enduro 3 includes preloaded TopoActive maps, providing comprehensive navigation features that the other two watches lack. The Instinct 3 offers breadcrumb navigation but no detailed maps, which can be limiting for serious explorers. Meanwhile, the Vertical 2 comes with 32GB of offline maps, allowing for extensive storage of routes and trails. This makes the Enduro 3 the best choice for those who require advanced mapping capabilities, while the Instinct 3 is better suited for casual users.
Durability test: Polymer vs Titanium
The Enduro 3 is crafted with a titanium bezel and a lightweight design at just 2.2 oz, making it exceptionally durable without adding bulk. The Instinct 3, made of fiber-reinforced polymer, is also rugged, meeting MIL-STD-810 standards for thermal, shock, and water resistance. The Vertical 2 has a titanium build as well, but its heavier weight of 2.6 oz might not be ideal for everyone. For users prioritizing durability and weight, the Enduro 3 clearly stands out.
