Swing it hard?
First time i heard such methods....
Mind elaborating....thanks
its like your uncle ask you to bang your non working radio!
watches often sit on the display for mths or yrs before human wrist. oil will sit low due to gravity...
some watch manual stated to you need to wear a week only test for accuracy !
so swing it might help... use it for HJ help!
