COROS Built Its Biggest, Brightest Display Into the Pace 4 Pro
The
COROS Pace 4 Pro is a titanium AMOLED sports watch built around the largest
screen COROS has put on any of its watches so far. It weighs 43 grams, measures
11.8mm wide, uses a titanium bezel, and runs for up to 60 hours on GPS tracking
alone. COROS built it for athletes who want a full-featured sports watch
without the bulk that usually comes with one.
A Screen Bright Enough for Full Sun
The
display measures 1.47 inches, packing over 200,000 pixels into a 466 by 466
resolution, covered in edge-to-edge sapphire glass, on a watch body just 11.8mm
wide. Brightness reaches 3,500 nits at noon, then automatically drops as low as
2 nits at 2AM so the screen isn't blinding in the dark. COROS states the screen
stays clearly visible in full sun, gyms, and indoor pools alike. An adaptive
refresh system shifts the screen's speed between 60Hz and 1Hz depending on
what's happening, staying smooth while someone pans across a map, then slowing
down to save power once they stop interacting with it. COROS states the watch
pairs its most advanced processor yet with twice the RAM of previous models,
making mapping faster and more responsive than on any earlier COROS watch. A
new, more advanced processor paired with twice the RAM of previous COROS
watches is built specifically to make that mapping experience faster and more
responsive.
Built From the Same Metal Used in Aircraft
The
watch body is machine-engineered from TC4 titanium alloy, the same category of
material used in aerospace parts, finished with a premium paint coating, paired
with the same sapphire glass used on the display to help maximize both
durability and battery capacity inside the case. On battery life, COROS rates
the watch at 60 hours in its High GPS mode, dropping to 45 hours if the
always-on display stays active, or 40 hours in Max GPS mode, dropping to 30
hours with the always-on display active. That's a notable jump from the previous
PACE Pro model, which COROS lists at 38 hours of GPS battery, a plastic bezel,
a 1.3-inch display, and mineral glass rather than sapphire. As one real example
of that battery life, COROS cites a full triathlon, a 2.4-mile swim, a 112-mile
bike leg, and a 26.2-mile run, finished in 11 hours and 48 minutes with 80%
battery still remaining. COROS states the combination of efficient software and
a larger battery is meant to get an athlete through a full week of heavy
training on a single charge. Compared with the previous PACE Pro, COROS's own
figures show GPS battery life roughly doubling from 38 to 60 hours, the bezel
material moving from plastic to titanium, the display growing from 1.3 to 1.47
inches, and the display glass upgrading from mineral to sapphire. To illustrate
real-world battery life, COROS cites a full triathlon, a 2.4-mile swim, a
112-mile bike ride, and a 26.2-mile run finished in 11 hours and 48 minutes,
with 80% of the battery still remaining afterward.
Maps and Sensors Built for Real Terrain
Dual-frequency
GPS reduces the signal distortion that normally comes from buildings, canyon
walls, or thick tree cover, giving more accurate pace and distance readings in
places where GPS usually struggles. The watch holds 32GB of onboard storage for
detailed offline maps, including street and trail names, contour lines, and
points of interest, along with turn-by-turn navigation and a "back to
start" function. Onboard sensors include a barometer, an ECG sensor, a
9-axis motion sensor, a thermometer, and a SpO2 sensor for blood oxygen
readings. The heart rate sensor uses a multi-channel PPG design, reading
accurately through the skin, and COROS states the watch body sits flush against
the wrist specifically to prevent the small shifts and movements that usually
distort heart rate data during intense workouts. That sensor data feeds into
customizable training zones, overnight heart rate variability tracking, and
daily stress monitoring. That sensor data feeds into customizable training zones,
overnight heart rate variability tracking, and daily stress monitoring.
Voice Notes, Six Training Tools, and Real Connections
A
built-in speaker plays alerts for pace, distance, and heart rate out loud, and
lets a runner record a voice note mid-run, whether that's a training
observation or something worth remembering later, without stopping or reaching
for a phone; the same speaker also handles hands-free calls. Dedicated
triathlon mode supports a full swim-to-bike-to-run session, and Multi-Sport
mode lets someone stack different activities, like a run followed by weight
training, into one connected session. The COROS companion app organizes
training data across six tools: Training Load, Pace Strategy, VO2 Max tracking,
a running-specific fitness score, structured workouts and training plans, and a
route builder. The app connects directly to Strava, AllTrails, and Komoot, and
the watch can also pair with additional heart rate monitors and action cameras.
The same 32GB of onboard storage used for offline maps also holds downloaded
music and audiobooks, controlled through built-in media playback controls. The
watch rounds out with safety alerts for early morning or late-night sessions
and a built-in flashlight.
