Coros Sports Watch

COROS is a high-end sports technology brand that has quickly risen to prominence in the endurance athlete community, particularly among mountain runners and triathletes. Founded in 2016, the brand focuses on high-performance GPS watches and training software capable of extreme battery life and durability. It rose to global fame through high-profile sponsorships of elite athletes like marathon world record holder Eliud Kipchoge.

While the brand holds a significant corporate and marketing presence in the United States, its manufacturing operations and back-end research and development are centered in China. The company is known for its vertically integrated approach, controlling much of the hardware and software development internally rather than outsourcing, which allows for frequent firmware updates and rapid evolution of their sports science metrics.
