Apple Watch and magnetic surfaces

Are there any problems by putting the watch on magnetic surfaces like metal tables? I have a metal table and by laying the watch on it you feel the typical magnetic force. Can this in some way harm the watch?

What about the magnetic charger cable? The downside of the magnetic charger is also magnetic and by putting this on the metal table it is the same behaviour.

Can these situations in some way damage or harm the watch?

Thank you!
