Apple Watch Ultra 3 Running & MultisportGarmin Forerunner 165, Running Smartwatch,

Design and Build Quality

The Apple Watch Ultra 3 features a rugged titanium case that is designed to withstand the rigors of adventure sports, making it a premium choice for those seeking durability. In contrast, the Garmin Forerunner 165 has a lightweight design with a traditional button control system, which makes it user-friendly but may not provide the same level of resilience as the Ultra 3. The Apple Watch Ultra 3 stands out with its sapphire crystal display, known for its scratch resistance, whereas the Forerunner 165 focuses on portability with its 43 mm size. Both watches cater to fitness enthusiasts but in different ways regarding their overall build quality.

Display Quality

The display of the Apple Watch Ultra 3 is notably larger and brighter, featuring advanced technology that enhances visibility at wider angles. This makes it particularly effective for outdoor activities. On the other hand, the Garmin Forerunner 165 is equipped with a colorful AMOLED touchscreen that delivers vibrant visuals but may not match the brightness levels of the Ultra 3. The disparity in display technology can affect usability in bright conditions, with the Ultra 3 providing a superior experience for users who require optimal visibility during workouts.

Battery Life

In terms of battery performance, the Garmin Forerunner 165 outshines the Apple Watch Ultra 3 in smartwatch mode, offering up to 11 days of battery life compared to the Ultra 3's multi-day usage of 42 hours. However, when utilizing GPS, the Ultra 3 lasts up to 20 hours in Low Power Mode, while the Forerunner 165 can function for up to 19 hours in GPS mode. This indicates that while the Forerunner 165 is better for everyday use, the Ultra 3 provides competitive battery life for intensive activities, catering to different user needs.

Health and Fitness Tracking Features

Both the Apple Watch Ultra 3 and Garmin Forerunner 165 are equipped with advanced health and fitness tracking capabilities. The Ultra 3 offers invaluable health insights, including notifications for hypertension and irregular heart rhythms, adding a layer of health management not found in the Forerunner 165. Nevertheless, the Forerunner 165 compensates with personalized workout suggestions and a variety of built-in activity profiles, making it a versatile option for various training regimens. The Ultra 3 serves as a more comprehensive health monitoring device, while the Forerunner 165 excels in adaptive training support.

Smart Features and Connectivity

The Apple Watch Ultra 3 boasts extensive smart features, including cellular connectivity that allows users to take calls and stream music without their iPhone. Its integration with Apple's ecosystem enhances usability for those who are already invested in Apple products. In contrast, the Garmin Forerunner 165 provides smart notifications when paired with a smartphone, allowing users to stay connected without overwhelming the user experience. While the Ultra 3 offers superior connectivity options, the Forerunner 165 focuses on efficiency and ease of use for fitness tracking.

Price Point

The price difference between the two devices is significant, with the Apple Watch Ultra 3 priced at $699.99, while the Garmin Forerunner 165 is available for $199.99. This makes the Forerunner 165 about 71% cheaper than the Ultra 3, which may appeal to budget-conscious consumers or those who prioritize functionality over premium features. The higher price of the Ultra 3 may be justified by its advanced features and build quality, but the Forerunner 165 provides excellent value for those seeking a solid running smartwatch without the additional costs.

Market Position and Popularity

In terms of market performance, the Garmin Forerunner 165 has a bestseller rank of 225, indicating a solid presence among running smartwatches. The Apple Watch Ultra 3, with a slightly higher rank of 415, still demonstrates its appeal but may cater to a different segment of users looking for a multifunctional smartwatch rather than solely a running device. The Forerunner 165's popularity suggests it meets the needs of many consumers, while the Ultra 3 targets those who seek a more comprehensive fitness and lifestyle solution.

Which should you buy?

Choosing between the Apple Watch Ultra 3 and Garmin Forerunner 165 ultimately depends on your specific needs and budget. If you prioritize advanced health tracking, a rugged design, and extensive smart features, the Apple Watch Ultra 3 may be worth the investment despite its higher price. However, if you are looking for a reliable, user-friendly running smartwatch with excellent battery life and fitness tracking capabilities at a significantly lower price, the Garmin Forerunner 165 is an outstanding choice. Both watches excel in their respective areas, providing unique value to different types of fitness enthusiasts.
