Garmin Instinct 3

Garmin's Instinct 3 series which launched in Australia in January 2025, marks a significant evolution in rugged GPS smartwatches. Designed for those who demand durability without compromising on modern features, this latest iteration introduces an AMOLED display to the Instinct lineup for the first time, offering vibrant visuals and improved readability in various lighting conditions .

The watch is available in two sizes—45mm, and 50mm—to cater to different wrist sizes and preferences. The 45mm AMOLED model, for instance, boasts a 1.2-inch display that delivers crisp, clear visuals, enhancing the user experience during workouts or daily use. 

Durability remains a cornerstone of the Instinct series. The Instinct 3 is built to military standard MIL-STD-810, ensuring resistance to thermal extremes, shock, and water up to 100 metres (10 ATM) . Its bolted construction, metal-reinforced bezel, and scratch-resistant lens make it a reliable companion for outdoor adventures.

Battery life varies across models. The standard AMOLED version offers up to 18 days in smartwatch mode, while the Solar variant can achieve unlimited battery life under optimal solar charging conditions—assuming all-day wear with 3 hours per day outside in 50,000 lux conditions . This feature is particularly beneficial for extended expeditions where charging opportunities are limited. 

Health and wellness tracking is comprehensive. The Instinct 3 monitors heart rate, stress levels, sleep patterns, blood oxygen saturation, and respiration. It also supports Garmin Coach for personalised training plans and offers recovery time suggestions post-workout . These features provide valuable insights for those aiming to optimise their fitness routines.

Navigation capabilities are robust, featuring multi-band GPS with SatIQ technology for accurate positioning even in challenging environments. The inclusion of a 3-axis compass and barometric altimeter further aids in navigation during outdoor activities 

Smart features include notifications for calls, texts, and app alerts when paired with a compatible smartphone. Garmin Pay enables contactless payments, adding convenience for users on the go . Additionally, the built-in LED flashlight is a practical tool for low-light situations, enhancing safety during nighttime activities.

In terms of pricing, the Instinct 3 series starts at an RRP of $729 for the 45mm Solar model while the AMOLED options start from $829. These options provide flexibility for users to choose a model that best fits their needs and budget.

Overall, the Instinct 3 series combines rugged durability with advanced features, making it a versatile choice for those seeking a reliable smartwatch for both everyday use and outdoor adventures.
