Audemars Piguet movement identification please

[Rogerg]

I am hoping that someone here can confirm the identity of the movement in my 18k AP ultra thin manual wind.

It looks like an entirely correct Audemars Piguet Calibre 2003 manual-wind movement, 36 hour power reserve and 1.64mm thin which is pretty damn impressive.

It's their ultra slim movement, Cal 2003, 1.64mm thick, developed in the mid-40's. Used by Vacheron Constantin and others. Super high qualty and fairly rugged for an ultrathin. I don't think AP uses it at the present time. I have it in an AP perpetual calendar.

Thank you both for the quick confirmation!!!!
