The battery has the storage capacity to pass 510 mA in an hour. If you discharge at half the capacity (0.5C) it will be empty after 2 hours.
If it was to draw 51 mAh it would last 10 hours.
But if it would draw 1020 mAh it would only last 30 minutes

So this is 510 mA per hour, I guess

This is the winning response I think.

Not really, it makes sense to give a max current. If a car’s top speed is listed as 200 km per hour, it does not mean that it goes this fast continuously.

I get this is a battery but the units don’t make sense unless it’s going at 100% all the time

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).

The max rating is important so your powersupply/battery can be sized accordingly. No powersupply can provide a abitrary current at their rated voltage.

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.
