About Coros
Introduction to Coros
Coros is a relatively young brand in the GPS watch market, having been founded in 2016 as a spin-off from the well-established sports technology company, Suunto. Based in Utah, USA, Coros was created with a singular focus: to provide athletes with high-performance GPS watches at competitive prices without compromising on accuracy or durability. The company's mission is to empower athletes of all levels by delivering reliable, data-driven tools that enhance training and performance.
Despite its youth, Coros has rapidly gained recognition for its innovative approach to watch design and technology. Unlike many competitors that prioritize flashy features or smartwatch capabilities, Coros has carved out a niche by focusing on core athletic needs-long battery life, accurate GPS tracking, and robust construction. This no-nonsense philosophy has resonated with runners, triathletes, and outdoor enthusiasts who demand precision without unnecessary frills.
Coros watches are designed for athletes who prioritize performance and durability.
Why Choose Coros Watches?
Coros watches stand out in a crowded market for several reasons. First and foremost is their exceptional battery life. While competitors like Garmin often require daily charging during multi-day activities, Coros models can last up to 50 hours in GPS mode (Pace 4) and even longer in UltraMax mode (Apex 2 Pro). This makes them ideal for ultramarathoners, hikers, and triathletes who need reliable tracking without worrying about power depletion.
Another key advantage is GPS accuracy. Coros uses dual-frequency GPS technology in its higher-end models, which reduces signal interference in urban areas or dense forests. The company also employs Barometric Altimeter for elevation tracking, a feature often reserved for premium-priced watches.
Durability is another hallmark of Coros watches. The Apex series, for example, features a sapphire crystal (on Pro models) and a robust titanium casing, making it resistant to scratches and impacts-ideal for trail runners and mountaineers. Even the more affordable Pace series uses fiber-reinforced polymer for lightweight yet durable construction.
Pros of Coros Watches
- Industry-leading battery life (up to 100 hours in UltraMax mode)
- Accurate dual-frequency GPS with barometric altimeter
- Lightweight and durable construction (titanium, sapphire crystal options)
- Affordable pricing compared to Garmin and Suunto for equivalent features

Cons to Consider
- Limited smartwatch features (no music storage, minimal app ecosystem)
- Smaller community compared to Garmin (fewer third-party resources)
- No touchscreen on most models (button-only interface)
- Fewer style options (Coros focuses on function over fashion)
- Slower software updates compared to Garmin

Coros Pace 3 GPS Watch Review
The Coros Pace 3 is the brand's third-generation running watch, succeeding the highly popular Pace 2. Released in 2023, the Pace 3 builds on its predecessor with significant improvements in battery life, display clarity, and sensor accuracy while maintaining an impressively lightweight design.
Priced at $249, the Pace 3 delivers features typically found in watches costing twice as much.

The 1.2" transflective memory-in-pixel (MIP) display offers excellent readability in direct sunlight, though it lacks color (unlike Garmin's AMOLED screens).
| Specification | Coros Pace 3 |
|---|---|
| Weight | 30g (with silicone strap) |
| Dimensions | 41.9mm x 41.9mm x 11.7mm |

Pros
- Lightweight and comfortable for all-day wear
- Excellent battery life at this price point
- Dual-frequency GPS for improved accuracy
- Bright, readable display in sunlight
- Affordable compared to competitors
Cons

Who Should Buy the Pace 3?
The Pace 3 is ideal for:
- Runners who want accurate GPS tracking without breaking the bank
- Triathletes needing a lightweight watch for brick workouts
- Casual athletes who prioritize battery life over smart features
- Budget-conscious buyers who don't want to pay Garmin-level prices
If your bedroom is under 200 sq ft and you sleep with a partner who moves a lot, the Pace 3's silent button interface won't disturb anyone-unlike touchscreen watches that can accidentally register taps.
The Coros Pace 3 is one of the lightest GPS watches available.
Coros Pace 4 GPS Watch Review
The Coros Pace 4, released in 2024, represents the brand's latest evolution in its popular Pace series.

|---|---|
| Weight | 35g (with silicone strap) |
| Dimensions | 46.5mm x 46.5mm x 12.5mm |
| Display | 1.4" MIP (240 x 240 pixels) |
