510mA per hour is nonsensical because A is an instantaneous measurement. 510 mAh/h is 510 mA. I guess you need a backpack to carry the battery around if you want the watch to last all day.
The battery has the storage capacity to pass 510 mA in an hour. If you discharge at half the capacity of 255 mAh (0.5C) it will be empty after 2 hours.
If it was to draw 51 mAh (0.1C) it would last 10 hours.
But if it would draw 1020 mAh (2C) it would only last 30 minutes
So this is 510 mA per hour, I guess. That or it just draws 510 mA continuously

This is the winning response I think.
