World Sleep Day 3.21

Do you know? March 21st every year is World Sleep Day.

COLMI released the world's first sleep actuarial watch in 2017. It has been 7 years since we have been working on how to use smart watches to accurately calculate users' sleep.

COLMI smart watches are now equipped with high-tech methods such as the fifth-generation sleep detection algorithm, which can increase the accuracy of sleep detection data to 97.3%, far exceeding other smart watches.
