Two posts from me after swinging in @ HK Flagship Boutique to pick up the latest catalog. This one first...

I spent some time again with this particular beauty. I had thought the 'A' was inscribed on the crown (as others have reported during the SIHH viewing), but clearly I was wrong - it is a regular crown. Still, the hands and the numerals make this a St Ex edition, although only to the more discerning eye. This timepiece also has the Calibre 89360/89361 movement, unlike the regular 2012 ardoise / sunburst dial Spitfire, with the newer, though different, Calibre 89365 movement.
Here are the pics - sorry, Blackberry, plastics, and yellow lighting are a terrible combination.
Absolutely love the hour/minute totalizer counter @ 12 o'clock...

the new buckle in red gold placed besides an older one in platinum. I am informed that the new larger size and design was to allow more contact with the fingers, making it easier to release by a tug, or even a strong flick.
