New proud owner of a Portofino 8 day (510104) - interested if anyone has any experience of wearing this watch to play golf, any risk to the movement?
Hello, welcome to the forum and congratulations on your new watch!
Shock primarily affects the balance wheel and the rotor of a movement. Since your 5101 is manually wound and does not have a rotor, only its balance will be susceptible. This is why the IWC equips the caliber 59210 with an incabloc protected balance for adequate shock-protection. Also, IWC states that it rigorously tests all of its watches (article: www.iwc.com/en/experiences/test-lab/).
However, given the degree of shock induced onto the watch while playing golf (especially during a tee off!), its best not to expose any mechanical watch (IWC or otherwise) to such shocks. Though I wear my pilots doppel thoughout most rigorous activities, I always draw the line when hitting the green!
Here's what IWC states in their FAQ section:
[i]Can I play sports with my IWC watch?
As a matter of principle, you should avoid strong vibrations and impacts (e.g. when playing golf or tennis, mountain biking etc.). A mechanical wristwatch is a precision instrument whose manufacture involves working to tolerances of hundredths or even thousandths of a millimetre. Repeated sharp impacts can have a negative influence on the movement’s accuracy or even cause damage.[/i]

Hope this helps!
I am such a lousy golfer that my swing just doesn't produce sufficient force to harm a mechanical watch. However, one time it just might --why would I want to ever take a chance?
To my thinking the risks can be remote but not worth it with any fine watch.
