Keeping time

[sullycape]

I have been trying to time my watch with time.gov and this is an observation I have made. After setting the watch exactly it tends to gain 2 seconds in the next couple of hours, and then gains about 15 seconds through the next 24 hours.

This morning I noticed that it held exactly 14 seconds fast all morning. I reset it again and again within a couple hours it had gained 2 seconds.

Does anyone know if my holding the second hand while setting the time has the effect of speeding up the watch?

My next test is to hold back 15 seconds to see if it normals out 15 seconds fast again which should put the time exact.

I know this is crazy...but its kid of bugging me.
