# Garmin Instinct 3 Renewed, 45 mm AMOLED GPS smartwatch

Garmin Instinct 3 is a renewed 45 mm GPS smartwatch with an AMOLED display, built-in LED flashlight and health and activity features. The listing describes up to 18 days of battery life, but gives no operating conditions for that figure. Its rugged construction claims and navigation features suit outdoor and multisport use, while the mixed rating evidence offers limited reassurance about the renewed unit.

## At a glance

- The listing claims an AMOLED screen, built-in GPS and a built-in LED flashlight with variable intensities and strobe modes.
- Navigation features listed by the manufacturer include a 3-axis compass, barometric altimeter and multi-band GPS with SatIQ technology.
- Health monitoring claims include wrist-based heart rate, sleep monitoring and Pulse Ox. The listing says Pulse Ox is unavailable in some countries and the watch is not a medical device.

## Pros

- Built-in GPS and listed outdoor navigation tools combine with activity tracking for running, hiking and cycling.
- The built-in flashlight has variable intensities and strobe modes, which can provide illumination without a separate torch.
- The listing names compatibility with both iOS and Android devices.

## Cons

- The supplied battery-life figure has no usage-mode conditions, so it does not establish how long the watch lasts with particular features enabled.

## Before you buy

- The listing identifies a 45 mm model and claims up to 18 days of battery life, but gives no battery-use mode or conditions. It also describes the case as fibre-reinforced polymer with a metal-reinforced bezel without clearly separating case and watch dimensions. Check the selected renewed listing for the exact configuration and battery claim. Pulse Ox is not available in all countries, and health data is an estimate rather than medical advice.

## In the box

- Garmin Instinct 3 Renewed (Included)
- Cable (Included)
- Documentation (Included)

## A good fit for

- Outdoor users who want built-in GPS, a compass, an altimeter and a wrist-based flashlight.
- Runners, hikers, cyclists and multisport users looking for activity and health tracking in a rugged-style watch.
- Buyers seeking a Garmin watch compatible with iOS or Android who are comfortable considering a renewed product.

## Less suited to

- Anyone who needs a guaranteed battery runtime for a specific GPS or display mode, since the listing supplies no usage conditions.
- Anyone relying on Pulse Ox in a country where it is unavailable or seeking a medical device.

## Customer feedback

The supplied evidence contains aggregate ratings only, with no customer comments to explain the spread. The distribution is mixed, including both five-star and one-star ratings, so it offers limited reassurance about the renewed unit. Buyers should weigh this uncertainty against their needs for GPS, health tracking and outdoor features, and check the selected renewed listing's condition and terms.

## Frequently asked questions

### How long does the battery last?
The listing states 18 days, also described as up to 18 days in the title, but does not specify usage modes or conditions. Treat it as a listing claim rather than a guaranteed runtime.
### Does this watch work with iPhone and Android?
The listing says it is compatible with iOS and Android devices. It does not provide more detailed compatibility requirements.
### Can I use its health readings for medical decisions?
No. The listing says the watch is not a medical device and that its health data is intended as a close estimate. Pulse Ox is not available in all countries.
### What is included with the renewed watch?
The explicit contents list names the watch, a cable and documentation. The listing describes the case construction separately, but does not identify a case as a separate package item.
