One of the main advantages on APEX, APEX Pro and VERTIX models when compared with other watches is the Digital Knob. With the Digital Knob, you can easily operate the watch using one finger to scroll or click. Even if you are in the middle of a workout or wearing thick gloves in subzero environment, Digital Knob is the ideal solution for operating your watch.
COROS has conducted rigorous tests to ensure the durability of the Digital Knob even in the toughest environments and user cases.
