How to affect the accuracy of your Rolex by positioning the watch while not in wrist?

[hoowee]

Hello, I’ve been years away from this forum. I’ve tried to find the info about this. Years ago there was even an info card how to get your Rolex to gain or lose some seconds by keeping the watch in different positions while not in your wrist.
Could please help me to find more info and discussions about this?
Thank you in advance for your help. Henry
