COROS PACE 4 Pro

iPhone and Android

COROS's first PACE with a titanium bezel and sapphire glass, released in September 2026 above the plastic PACE 4. Its 1.47-inch LTPO AMOLED is the largest display COROS has built, and COROS pairs it with a bigger battery, 32GB for maps and music, and a speaker for calls and spoken alerts. Against the earlier PACE Pro, COROS lists 60 GPS hours versus 38.

  • Headline: COROS spec: Daily Use & Sleep Tracking 21 Days.
  • Always-on: COROS spec: 7 Days (with Always-On Display).
  • GPS: COROS spec: High All Systems (GPS, GLONASS, Galileo, Beidou, QZSS) 60 Hours; 45 Hours with Always-On Display; 17 with offline music playing.
  • Dual-band GPS: 40 h.
  • Dual-frequency figure from the spec table (Max Dual Frequency 40 Hours, 30 with AOD); the product page FAQ calls it a 45-hour mode, so the spec table is used. COROS: 30 minutes of charging returns roughly 10 hours of GPS.

The ring’s outer track is the headline claim; the inner two are the always-on and GPS figures as a share of it. An empty track means COROS does not publish that figure. Why the figures differ

Phones, paid tier and updates

iPhone:
Yes.
Android:
Yes.
COROS app on iOS and Android; COROS lists Message/Call Alert on both, and its FAQ says the app syncs with Apple Health and Google Fit.
Paid tier:
No paid tier sold by the maker.
Software updates:
COROS does not publish a guaranteed number of update years for this model.

Cleared health features

COROS cites no regulator clearance for a health feature on this model. Its heart-rate, sleep and blood-oxygen readings are wellness features.

A clearance says what a feature is allowed to claim, not that it replaces a doctor. Cleared versus wellness features

What the extra money buys: Against the COROS PACE 4, the extra ~$200 buys 19 h more GPS time and a longer headline battery (21 days vs 19 days). See the COROS PACE 4.

Features, per COROS

  • 1.47-inch 466 x 466 LTPO AMOLED, 60Hz to 1Hz adaptive refresh, sapphire glass
  • Grade 5 titanium bezel; 43 g with nylon band
  • All-satellite dual-frequency GNSS
  • 32GB for Landscape and Topo global maps plus music
  • Speaker and microphone for hands-free calls, spoken alerts and Voice Pins
  • Electrical heart rate sensor for HRV and Wellness Checks
  • Triathlon and multisport modes

Where the specs put it ahead

  • Rated for 7 days with the screen always on, a figure that removes the usual reason to turn AOD off on an AMOLED watch
  • 60 hours of all-systems GPS covers a 100-mile race with margin to spare
  • Sapphire glass and titanium at 43 g with the nylon band, lighter than most titanium sport watches
  • Turn-by-turn topo maps and music share 32GB, so there is no maps-or-music trade-off
  • Speaker allows calls and spoken pace alerts, which the plastic PACE 4 lacks

What it gives up

  • No contactless payments; COROS states payment is not supported
  • Costs about the same as the APEX 4 46 mm, which has a longer MIP battery and better outdoor durability
  • 5 ATM rating, below the 10 ATM of the VERTIX line
  • No third-party app store, so smartwatch functions stop at notifications and media control

The two lists above are drawn from the maker’s own pages and prices, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.

What owners say

No owner discussion has been read for the COROS PACE 4 Pro yet. This section stays empty until there is something real to put in it.
