question about watch movement -advance

OmegaXRolex

If a watch is COSC certified - and it's runnning +1 fast per day or -4 per day.

Over time the watch will start losing or gaining time, how does a watch determine if it will start gaining time?

For example if a watch is running +1 second, over time will it start running like +10 seconds or will it start losing time and be -5 seconds per day. 

Anyone know how a watch will age and whether it will start losing or gaining time?
