2012 Audemars Piguet Royal Oak Selfwinding (Ref. 15400ST)


Following my “Audemars Piguet 2012″ overview – here is the new Audemars Piguet Royal Oak Selfwinding Ref. 15400.  This watch is given a new case size of 41mm, up slightly from the 39mm models of the past.  The applied AP initials appearing just above the logo are more discreet than on the previous 39 mm version.  They leave ample room at 12 o’clock for a double hour-marker inspired by the first Royal Oak watches launched in 1972.  Like the Ref. 15300 series, this reference will retain the AP automatic mechanical Calibre 3120 (also shown below).   The new Ref. 154000 Royal Oak Selfwinding 41mm model also comes in two other steel versions with a blue or silver-toned dial.  It is also available in pink gold with a choice of black or silver-toned dial, fitted with a pink gold bracelet or a leather strap with AP folding clasp (not pictured).

As is typical of the Royal Oak collection, the black dial of this new 41mm Royal Oak bears a “Grande Tapisserie” pattern that now becomes a signature for all Royal Oak selfwinding models.  This motif is crafted by Audemars Piguet using historical machines according to the ramolayé or pounced ornament technique.  This process enables simultaneous cutting of squares interspersed with a gridwork pattern of fine grooves.

    The OCD me can’t get over the fact that the Audemars Piguet logo is crooked!  Compare the top of the placard to the grid pattern…  Yikes!

      I have never seen the logo skewed on a genuine AP. Could it be a fake in the pictures?
