Polar Grit X | $430
Rating: ★ ★ ★ ★

Suunto 7 | $400
Rating: ★ ★ ★
Weight: 68g
Basics
This watch has a blend of full lifestyle functionality and medium-level single-sport training capabilities on a beefy touchscreen smartwatch.

- Fantastic GPS navigation display, offline maps, and popularity routing
- Good compatibility with Android via WearOS (works with Apple iOS as well)
Cons

Apple Watch Series 6 | $400 (40mm) | $430 (44mm)
Rating: ★ ★ ★
Weight: 47.1g
Basics
A lifestyle watch with an impressive level of bells and whistles standard in the Apple suite. New ECG and heart-rate features, along with Apple Fitness+, make it appealing for general fitness, but without the tri-specific functionality of a more sport-focused watch.
Pros
- Connection to a phone number enables some truly mind-blowing lifestyle features
- New ability to track ECG and heart-rate variability are nearly medical-grade
- Well-designed and pretty
- Comes in 40mm and 44mm sizes, with a variety of higher-end bands options
Cons
- Surprisingly poor battery life
- Workout modes are lacking in the features triathletes would expect
- Requires an iPhone
