The new model of the Swiss watch brand Audemars Piguet persuades – besides the extra flat mechanism – with hand manufactured ornaments and an oscillating weight, that can be personalized by the owner.
The case of the Royal Oak Selfwinding Perpetual Calendar (Ref. 26579CB.OO.1225CB.01) is made of with ceramic. As well the watch is equipped with non-reflecting sapphire crystal and a screwed crown. The case back is manufactured of sapphire crystal as well.
The blue dial of this Royal Oak is decorated with a ‘Grand-Tapisserie’ motif. The model has silvered counters, applied indices and the typical Royal-Oak-hands made of white gold and covered with luminescent coating. At the rim of the watch a blue flange is situated.
The watch is driven by the automatic calibre 5134, which is based in its predecessor, the calibre 2120, and has been revised due to the larger case size of 41 mm. The 4.31 mm high mechanism was made of 374 individual pieces and is visible through the watch’s case back. The caliber is selfwinding in both directions.
A special feature of this Royal Oak is the perpetual calendar. Other than that the new model has a flying spring house und a moon phase indication, which has been applied with micro structuring and has to be corrected only every 122 years and 108 days. The oscillating weight is situated on 4 rubin rolls with the help of a peripheric ring. This way friction can be reduced effectively.
The watch’s strap is, like the case, made of white ceramic and is equipped with a AP folding clasp made of titanium. The power reserve of the Royal Oak Selfwinding Perpetual Calendar is 40 hours.
