Really? I have a camera that is rated “3.7 V, 2 A” but only draws that amount from the battery when the flash capacitor is recharging. Yes, the normal current draw would be more helpful, and in case of a watch, the standby current.
This may be the charging current but it would be pretty unusual to pick a value slightly above what legacy USB can deliver (500 mA).
