IRVINE, CA — April 22, 2025 – COROS, the sports technology company behind the award-winning PACE 4, today announced the launch of COROS PACE 4 Black Crystal — an elevated design that brings premium materials and refined touches to the brand's lightest AMOLED GPS watch. Featuring a 6000-series aluminum alloy bezel finished with Physical Vapor Deposition (PVD) coating, injection molded translucent lugs, and a silk-screened silicone band, Black Crystal delivers a new look and feel built for athletes who value precision and purpose.

What to Know

• Aluminum Alloy Architecture — A 6000-series aluminum alloy bezel provides structural integrity and a smooth, refined finish ready to withstand the demands of an active life.
• Vapor Deposited Resilience — PVD bonds a matte metallic coating to the bezel at a molecular level, resisting sweat and salt for an elevated appearance that lasts.
• Details with Depth — Two-tone injection molding on the watch lugs creates a translucent, multi-layered look that gives PACE 4 Black Crystal a sophisticated, industrial edge.
• Uncompromisingly Light — Even with added aluminum, PACE 4 Black Crystal weighs just 32 grams with the nylon band.
• AMOLED At Its Best — A 2.5D touchscreen AMOLED display with a tapered edge delivers crystal-clear visibility in any light.
• Big Battery Life — Up to 41 GPS hours and 19 days of daily use, built into the most refined PACE design yet.

Hidden in Plain Sight

Black Crystal is a considerable upgrade from the original PACE 4. The aluminum alloy bezel is finished using Physical Vapor Deposition, a process that bonds the coating at a molecular level for lasting resistance to sweat, salt, and the wear of everyday training. On the lugs, two-tone injection molding adds a translucent, layered quality that goes well beyond a standard polymer finish — a detail athletes will notice up close and others will notice from a distance.

The silicone band carries the same attention to craft: a silk-screened ripple design, heat-cured directly into the surface for a permanent, high-definition finish that won't fade or peel over time.

"PACE 4 Black Crystal is designed for athletes who want their gear to reflect the same standards they bring to their training," said Lewis Wu, CEO and Co-Founder of COROS. "Every material choice — from the aluminum bezel to the PVD coating to the translucent lugs — was made to create something that performs exactly like PACE 4 and looks unlike anything else on the market."

All the Performance of PACE 4

Black Crystal retains everything that made PACE 4 the top-rated running watch of 2026 — including built-in voice features, advanced training metrics, and a redesigned heart rate sensor — now wrapped in a finish worthy of the watch inside.

• Built-In Mic — Record training notes or capture Voice Pins mid-run with the built-in microphone.
• Complete Activity Details — Upload photos, videos, and Voice Pins directly to each activity.
• COROS App: Training, Recovery & Health Hub — Track recovery time, sleep stages, HRV, menstrual cycles, and detailed training metrics to understand how your body is responding to training.
