- Excellent battery life with up to 19 days of regular use
- Bright and sharp AMOLED display is rarely seen at this price
- Lightweight and comfortable, but clearly plastic in build
- Lacks everyday smart features like payments and music
The Coros Pace 4 is a watch that knows exactly who it is for. This is not a lifestyle smartwatch trying to please everyone. It is a lightweight, performance-focused training companion aimed squarely at runners, triathletes, and cyclists who care more about splits and stamina than streaming playlists.
With up to 19 days of battery life and a sharp AMOLED display, it undercuts many rivals on price while still offering dual frequency GPS and dependable health tracking. At 249 dollars or 229 pounds, it lands in the same territory as more general-purpose wearables, yet its priorities are very different. The question is simple. Does that focus pay off?
A brighter screen without sacrificing stamina
The biggest change from the previous generation is the move to a 1.2 inch AMOLED touchscreen. It replaces the older memory in pixel display with a far sharper 390 x 390 resolution panel that reaches 1,500 nits of brightness. Outdoors, whether under strong sunlight or grey skies, visibility is excellent. Text and charts look crisp and modern, giving the Pace 4 a welcome visual lift.
AMOLED screens are usually tough on battery life, but Coros has balanced the equation well. The company claims up to 19 days of daily use or 41 hours in high GPS mode. In real world testing with several runs and rides per week, the watch comfortably lasted between ten and fourteen days.
That is impressive for a device with this kind of display and puts it ahead of many similarly priced competitors.
Charging is handled by a proprietary magnetic cable that snaps neatly into place. It is simple and secure, though as always with custom chargers, you will want to keep it safe.
Built for runners, not for show
Pick up the Pace 4 and you will immediately notice how light it feels. At just 32 grams with the nylon strap, it almost disappears on the wrist. The fiber-reinforced polymer case does not scream luxury, but the trade-off is comfort. During long runs and interval sessions, the watch never feels intrusive.
Navigation is handled through a hybrid three-button system that includes Coros signature digital dial and an action button. It is intuitive and reliable, even with sweaty hands or gloves. The interface is clean and straightforward, avoiding clutter in favor of speed.
Where the Pace 4 draws a firm line is in its smart features. There is no NFC for payments, no music streaming apps and no ability to reply to messages. If you want a smartwatch that handles calls and acts as a mini phone on your wrist, this is not it. The Pace 4 sticks to training first, everything else second.
Performance that punches above its price
Under the hood, the Ambiq Apollo 510 processor keeps things moving smoothly. Menus load quickly and tracking sessions start without delay. Health metrics such as heart rate and cadence are largely reliable, thanks to an updated optical sensor array with five LEDs and four photodetectors.
The dual-frequency GNSS chipset connects to multiple satellite systems and locks on quickly, even in built-up areas.
In side-by-side comparisons with more expensive watches, the Pace 4 was usually within a small margin of error for total distance. It is not laboratory-grade precision, but it is more than accurate enough for most runners and cyclists.
One feature that stands out is the integrated voice tool. Voice Pins allow you to record short notes mid-run and tag them to specific locations, while Voice Notes let you log thoughts after a session. It is a clever way to capture how a workout felt without stopping to type.
The main limitation on the navigation front is the lack of full offline maps. You get breadcrumb-style routing with turn-by-turn directions for planned routes, but nothing more detailed. For road runners, this may be fine. Trail explorers might want something more advanced.
Value that is hard to ignore
At 249 dollars or 229 pounds, the Coros Pace 4 sits in an attractive position. It offers features that are often reserved for pricier watches, including AMOLED, dual band GPS and long battery life. What you sacrifice are premium materials and lifestyle extras.
For athletes who want a dependable training partner that can go nearly two weeks between charges, the Pace 4 makes a compelling case. It is not trying to be the flashiest watch on your wrist. It is trying to help you train smarter, and in that respect, it succeeds.
