Garmin Instinct E GPS 40mm Smartwatch Review: Best for Swimming?

Looking for a capable GPS smartwatch that can keep up with your active lifestyle without breaking the bank? We’ve been examining the Garmin Instinct E, a smaller 40mm option that brings many solid features to the table. It’s built tough with water resistance up to 10 ATM and meets military standards for thermal and shock resistance, so it should handle rough conditions.

The battery life stands out at up to 14 days on a single charge, which means less time worrying about plugging it in.

Navigation tools include a 3-axis compass and barometric altimeter with multi-GNSS support for tracking your location. Smart notifications work when paired with your phone, and you can download additional apps and watch faces through the Connect IQ Store. Safety features like incident detection during certain activities and assistance functions send your location to emergency contacts when needed, though you’ll need your phone nearby with network coverage.

Customer feedback shows an average rating of 4.2 out of 5 from over 160 reviews. People seem to appreciate the rugged build and long battery life, though some mention the smaller screen size takes getting used to. The sports apps cover basic activities well, but the feature set is more focused on essentials rather than advanced training metrics.

Bottom Line

The Garmin Instinct E offers practical features in a tough, compact package with impressive battery life.

If you want a reliable GPS smartwatch that covers the basics without unnecessary complexity, this model deserves your attention.

Overview of the Garmin Instinct E GPS 40mm Smartwatch

This rugged GPS smartwatch stands out with its compact 40mm size, making it a good fit for smaller wrists whilst maintaining a tough exterior. The Instinct E is built to military standards for thermal and shock resistance and carries a 10 ATM water rating, which means it can handle serious outdoor conditions.

Battery life reaches up to 14 days on a single charge, which is impressive for a GPS-enabled smartwatch. You get essential health tracking features like wrist-based heart rate monitoring, sleep tracking, and Pulse Ox sensors, though Garmin notes these aren’t medical-grade measurements.

The watch includes built-in sports apps, a 3-axis compass, and barometric altimeter for navigation. Smart notifications work when paired with your phone, and you can download additional watch faces through the Connect IQ Store.

Safety features include incident detection and assistance that can alert emergency contacts, though both require your phone to be nearby with network coverage.

Key Features

The Instinct E packs several notable features into its compact 40mm case. This smartwatch aims to balance durability with everyday functionality for people who want basic tracking without complicated extras.

Rugged Supertough Design and Water Resistance

The watch meets MIL-STD-810 standards for thermal and shock resistance. This means it can handle temperature changes and impacts better than standard smartwatches.

The 10 ATM water rating allows the device to withstand pressure equivalent to 100 metres underwater. You can wear it whilst swimming, showering, or doing water sports without worry.

The smaller 40mm case size makes it more comfortable for people with smaller wrists. At just 41 grams, it won’t feel heavy during long wear sessions.

The trade-off for this toughness is the relatively small 0.86-inch screen. Reading detailed information might require better lighting conditions than larger displays.

Comprehensive Health and Fitness Tracking

The Instinct E monitors your heart rate directly from your wrist throughout the day. It tracks your sleep patterns and provides information about how well you rest each night.

Pulse Ox sensors measure your blood oxygen saturation levels. This feature isn’t available in all countries and provides estimates rather than medical-grade data.

Built-in sports apps let you track different activities without setting up custom profiles. The watch automatically records basic metrics like duration, distance, and calories burned.

We appreciate that Garmin clearly states this isn’t a medical device. The health data serves as estimates to help you understand general trends rather than precise measurements.

Precision Navigation Tools

A 3-axis compass helps you maintain your bearing during outdoor activities. The barometric altimeter tracks elevation changes as you hike or climb.

Multi-GNSS support means the watch connects to multiple satellite systems beyond just GPS. This includes GLONASS and Galileo, which improves location accuracy in challenging environments like dense forests or urban areas.

The 128 MB of memory storage is quite limited compared to premium models. You won’t store large amounts of route data or detailed maps on this device.

Battery life reaches up to 14 days in smartwatch mode. GPS tracking drains the battery faster, but you’ll still get reasonable use between charges for most activities.

Smart Connectivity and Notifications

When paired with your smartphone via Bluetooth, you receive notifications directly on your wrist. Text messages, calls, and app alerts appear on the display so you don’t need to check your phone constantly.

The Connect IQ Store integration lets you download new watch faces and apps. This adds some customisation options, though the selection for this model may be more limited than Garmin’s premium watches.

Safety features include incident detection during certain activities and an Assistance function. Both send your live location to emergency contacts through your paired smartphone. These require network coverage and prior setup to work properly.

The Garmin Connect app syncs your data and provides detailed analysis of your health and fitness information. You’ll get personalised insights based on your activity patterns over time.

Battery Performance

The Instinct E stands out with its impressive 14-day battery life between charges. This means you can wear it for two full weeks without needing to find a charger, which is helpful for people who travel often or simply don’t want to worry about daily charging.

The watch uses a lithium ion battery with a 10,000 milliamp hour capacity. This large battery works together with the watch’s efficient design to achieve that extended runtime.

We found that the battery performance makes this watch more practical than many smartwatches that need charging every day or two. However, keep in mind that heavy use of GPS features and apps will drain the battery faster than the advertised 14 days.

Comfort and Wearability

The watch features a smaller 40mm case size that aims to fit a range of wrist sizes. However, we noticed a common complaint about the strap length being too short for some users, particularly those with larger wrists. Several people mentioned needing to purchase an extended strap separately to get a proper fit.

On the positive side, the rugged design doesn’t seem to compromise everyday comfort. People found it easy to wear throughout the day and during activities. The smaller case size works well for those who prefer a less bulky watch on their wrist.

The strap issue is worth considering before purchase. If you have a larger wrist, you may need to budget for an aftermarket strap to ensure a comfortable fit.

Pros and Cons

After looking at what buyers say and examining the features, we’ve identified the main strengths and weaknesses of this GPS smartwatch.

Pros

The Instinct E delivers impressive battery life that lasts up to 14 days on a single charge. This means less time worrying about finding a charger during your daily activities.

The watch meets military standards for thermal and shock resistance and has a 10 ATM water rating. These features make it capable of handling tough conditions without failing.

We found that the display remains visible in bright sunlight and various lighting conditions. Users report that the menus are straightforward to navigate, which makes accessing different functions quick and simple.

The device includes built-in sports apps, a 3-axis compass, barometric altimeter, and multi-GNSS support for navigation. Health monitoring features track heart rate, sleep patterns, and Pulse Ox readings from your wrist.

Smart notifications keep you connected to your phone, and the Connect IQ Store lets you add new apps and watch faces. Safety features like incident detection and assistance can alert emergency contacts with your location when paired with your smartphone.

Cons

The strap length poses a significant problem for many buyers. Multiple people report that the standard strap is too short to fit comfortably around larger wrists, which requires purchasing a separate, longer strap.

The 40mm case size is smaller than some expect for a rugged outdoor watch. Some users find this size too compact for their preferences.

The watch doesn’t come with a charging plug in the box. You only get a USB-C cable, which means buying a separate plug if you don’t already have one compatible with USB-C connections.

The price point sits on the higher end, which some buyers consider steep for the features offered.

Customer Reviews

Buyers give this Garmin watch mostly positive feedback, with many praising its battery life and range of functions. Several reviewers mention the watch does what they need and recommend it to others.

The strap sizing appears to be a common complaint. Multiple customers report the band is too short for larger wrists, with some needing to purchase a longer strap separately. A few buyers also note the watch face feels small for their preferences.

Some purchasers express frustration about needing to buy a separate charging plug since the included cable is USB-C only. However, most reviews focus on satisfaction with the watch’s features and durability.

The display gets praise for being easy to read in different lighting conditions. Users appreciate the simple menu navigation and the variety of built-in functions available.

Conclusion

After looking at what the Instinct E offers, it’s clear this watch delivers solid performance for its price point. The battery life stands out as a major strength, and buyers appreciate the range of sports features and durable build quality.

However, we need to address the strap sizing issue that multiple users mentioned. Some found it too short for larger wrists, which is disappointing for a watch marketed as rugged and adventure-ready. The lack of a charging plug in the box is another consideration, as you’ll need a USB-C adapter separately.

Overall, this is a capable smartwatch for those wanting basic fitness tracking and smart features without complexity. Just be prepared to potentially purchase an additional strap or charging adapter depending on your needs.

Frequently Asked Questions

How does the Garmin Instinct E 40mm perform for swimmers in terms of tracking capabilities and accuracy?

The Instinct E includes built-in sports apps that cover various activities, though it’s positioned as an entry-level model with essential features rather than advanced swim metrics. The watch uses GPS tracking and heart rate monitoring from the wrist to record basic workout data.

Users note that the watch captures general activity information during swimming sessions. However, the Instinct E doesn’t offer the same detailed swim-specific metrics found in higher-end Garmin models. It tracks time and heart rate data but may not provide stroke counts or SWOLF scores that dedicated swimmers often want.

What are the waterproof specifications and limitations of the Garmin Instinct E 40mm when used in water?

The watch has a 10 ATM water rating, which means it can handle pressures equivalent to 100 metres of depth. This rating makes it suitable for swimming in pools and open water, as well as snorkelling activities.

The MIL-STD-810 engineering provides additional durability against various environmental conditions. While the 10 ATM rating supports swimming use, it’s important to understand that this is a pressure rating rather than a depth recommendation for diving.

Can the Garmin Instinct E smartwatch measure different swimming styles, and if so, which ones?

The Instinct E doesn’t appear to offer automatic swimming style detection based on the available specifications. As an entry-level GPS smartwatch with essential smart features, it focuses on basic activity tracking rather than advanced swim analytics.

The watch can track swimming as a general activity through its built-in sports apps. However, we don’t see evidence that it differentiates between freestyle, breaststroke, backstroke, or butterfly strokes automatically.

What is the battery life of the Garmin Instinct E 40mm during extended swimming sessions?

The watch offers up to 14 days of battery life in smartwatch mode. However, actual battery performance during swimming sessions will be shorter because GPS tracking and continuous heart rate monitoring use more power.

When GPS is actively tracking a swimming session, the battery drains faster than during regular daily wear. The 10,000 milliamp hour battery capacity provides decent endurance, but extended swimming workouts will reduce the overall time between charges. Users should expect to charge more frequently if they swim regularly or use GPS tracking often.

How does the Garmin Instinct E 40mm compare to the Garmin Instinct 2S in terms of swimming features and functionality?

The Instinct E is positioned as a more affordable option with essential features, whilst the Instinct 2S typically includes more advanced tracking capabilities. The “E” designation suggests this is an entry-level model in the Instinct range.

Both watches share the rugged design with 10 ATM water rating and MIL-STD-810 durability. The key difference lies in the depth of features available. The Instinct 2S generally offers more detailed swim metrics and additional sport profiles compared to the Instinct E’s essential approach.

The 40mm case size on the Instinct E is smaller, which some users mention affects their experience. The Instinct E uses 128 MB of memory storage and runs on Garmin OS, providing basic smart notifications and Connect IQ Store access.

What user feedback is available regarding the Garmin Instinct E 40mm’s reliability for swimming activities?

The watch has received a 4.2 rating from 163 users, indicating generally positive reception. Reviewers highlight good quality construction and plenty of functions for the price point.

Some users express concerns about the physical design rather than swimming performance specifically. Multiple reviews mention that the strap is too short for some wrist sizes, which one user described as problematic for an adventure watch. The 40mm case size also receives feedback about being too small from certain users.

Battery life gets positive mentions in reviews, with users noting it performs well in this area. People appreciate the range of functions available, though some are still working through the manual to understand all features. The watch’s durability and build quality receive favourable comments, suggesting it holds up to regular use including water activities.
