As for my acoustical observations, you are right. I have no comparisons in mind, other than the Sonata, the Master Minute Repeater, and my Alarms.
So, I was expecting a louder sound. But never heard other " music box " on the wrist.
It had to be added, indeed.
As well as the typical construction of the " music box ", compared to the Sonata or the JLC Minute Repeater ( whose gongs are welded to the sapphire ).
I heard the same explanation about Rolf's wife nails, but on the Jade... As for the crown.
Good to have an owner's feedback.
Spending only one hour with a Watch cannot be compared to an owner's experience. Thank you so much for that.
All the best, my friend.
