As the Amvox I and the new Memo don't share the same Caliber, and that also makes a difference.
So you should better compare the sound of a Navy Seals Alarm ( in titanium ) and the new Memo, in SS.
So, you will appreciate the difference.
As for the International, this is more a decoration than a complication, as it is far from working like a PP WT.
But it is a very cool watch, full of nostalgia, and Dreams.
Best,
