The main difference between the Snapdragon Wear 4100 and 4100+ is the presence or absence of the coprocessor "QCC1110" for always-on (AON). The Snapdragon Wear 4100+ equipped with this coprocessor can monitor your heart rate and tilt to detect sleep and awakening faster, and can support alarms, timers, step counts, and tactile feedback to display the screen. You can increase the number of colors from 16 to a maximum of 64,000. High-performance smart watches will be ranked as 4100+, and low-priced devices will be ranked as 4100.

Qualcomm has already begun shipping both SoCs, explaining that manufacturers may announce onboard devices in the coming months.
