COROS Pace 4 vs. Pace Pro: Which Lightweight Sports Watch is Right for You?

Display Technology and Size

• 💡 Both the COROS Pace 4 and Pace Pro feature bright, colorful AMOLED displays, a shift from COROS's previous use of memory-in-pixel displays.
• 🎯 The Pace Pro offers a larger 1.3-inch display compared to the Pace 4's 1.2-inch screen, with both boasting a peak brightness of 1500 nits.
• 📏 A key difference is size: the Pace 4 has a 43mm case, designed for a smaller, lighter feel, while the Pace Pro is larger at 46mm, potentially better suited for those who prefer a bigger watch.

Design and Wearability

• 👟 While both watches use standard 22mm bands, the Pace 4's silicone band has an integrated design that may fit smaller wrists less comfortably than the Pace Pro's.
• ⚖️ Both are lightweight, with only a slight weight difference (around 5-9g) between them, emphasizing COROS's focus on comfortable, unobtrusive wearability.
• 🛠️ Construction is similar, with both featuring a plastic case, mineral glass lens, and a 5 ATM water resistance rating.

User Interface and Features

• 👆 Both watches have a touchscreen, a rotating dial, and a back button, but the Pace 4 adds an action button on the left side.
• 🗺️ The Pace 4's action button is useful during workouts for navigating maps and can be customized for other shortcuts, though it has no current everyday use.
• 🎤 A new addition to the Pace 4 is a microphone for voice notes, which are automatically transcribed and synced to the COROS app, though voice notes can also be taken via the app on the Pace Pro.
• 🎵 Both support MP3 playback via Bluetooth earbuds, with the Pace Pro offering 32GB of storage (primarily for maps) compared to the Pace 4's 4GB.

Health and Performance Tracking

• ❤️ Both models include heart rate and SpO2 sensors, sleep tracking, and other standard health metrics.
• 🩺 The Pace Pro uniquely features ECG hardware for on-demand wellness checks, providing more accurate heart rate and HRV readings, though it's not FDA-cleared.
• 🏃‍♂️ All sport profiles, training feedback metrics (like running performance, FTP estimation, training load, recovery time), and dual-band satellite chipsets for accurate GPS tracking are identical across both watches.

Navigation and Key Differentiators

• 📍 The Pace 4 offers breadcrumb-style navigation with a back-to-start feature and the ability to load routes for turn-by-turn directions.
• 🗺️ The Pace Pro's standout feature is its support for offline topo maps, providing detailed context of surrounding streets and trails, making it superior for navigation in unfamiliar areas.
• 💰 Ultimately, the Pace Pro's key advantages are its maps and larger display, while the Pace 4 counters with its action button and microphone; however, size preference may be the most significant deciding factor.
