Actually, both of your points are incorrect. In the case of Rolex's "perpetual", that's exactly what it's referring to-the fact that it's self-winding. It has nothing to do with a perpetual calendar. My Deepsea says "Oyster Perpetual Date" on its face, and I assure you it isn't a perpetual calendar. It's a self-winding watch using their Oyster case with a date complication.
And a chronograph is a stophttp://cdn.macrumors.com/vb/images/editor/menupop.gif watch.
Perpetual date, doesn't this give you any thoughts? It is just that all Rolex watches are all automatic today that they do not mention this specifically, in general perpetual refers to the date/calendar function. However, not all Rolex watches are perpetual.
Just see the Rolex Celline time:http://www.rolex.com/watches/cellini-time/m50509-0005.html.
Rolex mentions that it is self-winding, but is not referred to as perpetual.
On the chronograph, your are right I should have referred to the term chronometer.
