Audemars Piguet Royal Oak

Original early 70's Royal Oak - the one that started it all

Movement: cal 2121 - based on cal 2120 - "thinnest automatic movement in the world"
Features: Notice the AP logo below the center of the dial; the long thin solid (no luminous) baton hour markers, and clous de paris hobnail dial pattern. I have seen versions with both solid and luminous filled markers.

Movement: cal 2140 (?)
Features: This is a rare variant released in 1978, with full bar markers all around, double bars at 12:00 and 6:00, without the AP logo anywhere on the dial. I believe this is an early version of the ref. 15 000, with center sweep seconds and using the cal. 2140.
