Coros PACE 4 Premium Sport Watch with Silicone Band - Cloud White

Stealth-Inspired Precision — The Ultralight AMOLED GPS Sport Watch, Now with a Premium Aluminium Bezel - Cloud White

The COROS PACE 4 Aluminium — known as Black Crystal — is a premium edition of COROS's award-winning ultralight AMOLED GPS sport watch, built for athletes who value both performance and refined design. A 6000-series aluminium alloy bezel finished with Physical Vapor Deposition (PVD) coating adds structural integrity and a matte metallic finish, while translucent two-tone injection-moulded lugs and a silk-screened silicone band give it a sophisticated, industrial edge. Beneath the upgraded exterior lies the same PACE 4 performance platform: a vivid 1.2" AMOLED touchscreen, up to 41 hours of GPS, dual-frequency satellite tracking, a built-in microphone, and advanced training tools — all in a package that weighs just 33 grams with the nylon band.

• 6000-Series Aluminium Alloy Bezel with PVD Coating: A precision-machined aluminium bezel provides a structurally rigid, premium frame. Physical Vapor Deposition bonds a matte metallic finish at a molecular level, resisting sweat and salt to maintain an elevated appearance over years of training.
• Translucent Two-Tone Injection-Moulded Lugs: Two-tone injection moulding on the watch lugs creates a multi-layered, translucent appearance that adds depth and a sophisticated, industrial aesthetic beyond standard polymer construction.
• Silk-Screened Silicone Band: The ripple-pattern design is heat-cured directly into the silicone band for a permanent, high-definition finish that won't peel or fade.
• Vivid 1.2" 2.5D AMOLED Touchscreen: A tapered-edge AMOLED display delivers vivid colour, 1,500 nits of brightness, and crystal-clear visibility in any lighting condition — including direct sunlight — with 164% higher resolution (390×390px) than the previous generation.
• Ultralight at 33 Grams: Despite the added aluminium bezel, PACE 4 Black Crystal weighs just 33g with the nylon band — barely more than the standard polymer model — making it one of the lightest feature-rich GPS sport watches available.
• Up to 41 Hours GPS Battery Life: Delivers up to 41 hours in All-Systems GPS mode and up to 31 hours in All-Systems + Dual-Frequency mode — with 19 days of daily use between charges, outperforming most AMOLED sport watches at this price point.
• Dual-Frequency GPS (All-Systems Mode): Pulls signals from every major satellite constellation using dual-frequency technology for improved accuracy in urban environments, dense forest, canyons, and other signal-challenging conditions.
• Built-In Microphone: Record hands-free training notes, log perceived effort after intervals, or drop Voice Pins mid-run — all via the built-in mic, without needing to touch your phone.
• Redesigned Optical Heart Rate Sensor: Larger LEDs and a more secure fit reduce data spikes and drops during movement, delivering more reliable heart rate data across all training intensities and activity types.
• Advanced Training Tools: Running Fitness, Race Predictor, Virtual Pacer, interval training, structured workouts, and personalised marathon training plans help athletes of all levels unlock better performance and target their next PR.
• Health & Recovery Tracking: Tracks steps, sleep stages, HRV, recovery time, and menstrual cycles — both on the watch and via the COROS app — to help you understand how your body is responding to training load.
• VO₂ Max, Lactate Threshold & Running Fitness Metrics: Calculates advanced performance metrics from training history, pace, and heart rate data to give athletes a detailed picture of their endurance and recovery capacity over time.
• Route Navigation with Off-Course Alerts: Sync routes from Strava, RidewithGPS, or Wikiloc, or create them directly in the COROS app. Breadcrumb navigation guides you along the route with off-course alerts if you stray.
• Media & Phone Controls: Control music or podcasts playing on your paired phone — adjust volume, skip tracks, or pause — directly from the watch face.
• MP3 Music Storage: Store and play MP3 files directly on the watch via Bluetooth headphones (note: streaming services such as Spotify are not supported — files must be uploaded from a computer).
• Display-Based Flashlight: The AMOLED screen doubles as a wrist-mounted flashlight for low-light runs or navigating in the dark.
• 5 ATM Water Resistance: Rated to 50 metres depth, suitable for swimming, open-water training, and all-weather use.
• Altimeter, Barometer & Compass: Built-in sensors support trail running, hiking, and climbing activities with accurate elevation, weather, and directional data.
• 22mm Band Compatibility: Standard 22mm lug width maintains compatibility with existing COROS and third-party bands — nylon or silicone.
