Garmin Instinct 3 AMOLED vs Solar: Which One Should You Buy?

With the Instinct 3 Series, Garmin has given users a choice they’ve never had before — the ruggedness of the Instinct line now comes in both Solar and AMOLED variants.

But which one is the right pick for you?

Let’s compare them across critical dimensions to help you decide.

1. Display Technology

The most obvious difference lies in the display. The Solar model uses a transflective MIP display, offering excellent visibility under direct sunlight. It's perfect for outdoor adventures.

The AMOLED model, on the other hand, offers a vibrant, high-contrast screen that’s great for readability indoors or at night.

2. Weight and Size Options

Both models are available in 45mm and 50mm sizes, but the Solar variant is slightly lighter due to the absence of an AMOLED screen.

Both watches are comfortable for all-day wear.

3. Battery Life

The Solar model is the clear winner in battery life. With sufficient sun exposure, it can offer unlimited battery life, and with one charge, it can offer up to 40+ days in smartwatch mode and several weeks in expedition GPS mode.

The AMOLED version, while offering rich visuals, comes with a trade-off — it provides up to 24 days in smartwatch mode and 30 hours in GPS mode.

Battery life of the 50 mm sizes is higher than the 45 mm in both models.

4. Pricing

Across global markets, including India, the Garmin Instinct 3 AMOLED commands a premium due to its advanced display and refined design.

In the 45 mm size, the AMOLED variant is priced at ₹52,990, while the Solar version costs ₹46,990.

In the larger 50 mm size, the AMOLED model is priced at ₹58,990, whereas the Solar version is available at ₹52,990.

This price difference of approximately ₹6,000 is consistent in many countries and reflects the cost of the brighter, high-resolution AMOLED screen.

While both models are packed with advanced tracking and rugged durability, your choice may come down to priorities.

For users focused on long outdoor expeditions and battery life, the Solar version delivers unmatched value.

However, if visual appeal, display clarity, and modern styling are key for you, the AMOLED is worth the additional investment.

It’s also worth noting that the 45 mm size is often more suitable for Indian users, especially those with smaller wrists.

It offers all the features of the larger version in a more compact, lightweight form — ideal for all-day wear without compromising on capability.

5. Outdoor Usability

The Solar model shines during long treks and hikes where power sources are scarce.

If you’re into mountaineering or camping, the ability to extend your battery life through solar charging is a huge advantage.

Meanwhile, the AMOLED model is better suited for mixed-use offices, gyms, and outdoor activity, especially if you prefer a more premium look.

6. Health and Wellness Features

Both watches offer the same robust suite of health tracking features — heart rate, Pulse Ox, stress tracking, sleep scores, HRV status, and more.

Neither model compromises here.

7. Smart Features

Both support smart notifications, Garmin Pay, music controls (not storage), and integration with Garmin Connect.

The AMOLED model’s display makes interacting with these features more enjoyable.

Verdict

• Choose Solar if you prioritize battery life, especially for long outdoor excursions.
• Choose AMOLED if you want an eye-catching screen and plan to use the watch in everyday urban settings.

Either way, the Instinct 3 Series has something for everyone — and it’s a win for Garmin fans.
