Audemars Piguet Royal Oak Double Balance Wheel Openworked 41 mm 15412BC.ZZ.1220BC.01 White Gold/Diamonds Analog Audemars Piguet Royal Oak Double Balance Wheel…

The Audemars Piguet 15412BC.ZZ.1220BC.01 is the Royal Oak Double Balance Wheel Openworked in 41 mm 18-carat white gold, with 32 baguette-cut diamonds set in the octagonal bezel. Its slate grey openworked dial, with pink gold applied hour markers and Royal Oak hands with luminescent coating, shows the self-winding calibre 3132 and its patented double balance wheel, which can also be seen through the sapphire case back. The white gold bracelet is integrated into the case. Bizak & Co. lists it from $303,850.

What sets the 15412BC.ZZ.1220BC.01 apart

• Two balance wheels on one axis. Calibre 3132 fixes a second balance wheel and balance spring on the same axis as the first. Audemars Piguet patented this geometry and says that, although it is very complex to manufacture, it greatly improves precision and stability. Audemars Piguet specifies the calibre at 26.6 mm across and 4.4 mm thick, with 38 jewels, 245 parts, a frequency of 3 Hz (21,600 vph) and a 45-hour power reserve; it shows hours, minutes and centre seconds, without a date.
• 32 baguette diamonds on the bezel. The 18-carat white gold bezel is set with 32 baguette-cut diamonds, the same number of baguettes Audemars Piguet sets on the sapphire 15412BC.SS.1220BC.02 and the Swiss topaz 15412BC.TO.1220BC.01. Unlike those two, the ZZ keeps applied gold hour markers rather than gem-set ones, so its only gem-setting is the bezel.
• The slate grey openworked dial. It has the slate grey openworked dial, pink gold applied hour markers and Royal Oak hands with luminescent coating that Audemars Piguet also uses on the steel 15407ST.OO.1220ST.01, the pink gold 15407OR.OO.1220OR.01 and the black ceramic 15416CE.OO.1225CE.01, here paired with white gold and diamonds.
• The white gold case. The 41 mm case is 18-carat white gold, and Audemars Piguet lists the 15412BC case at 10.1 mm thick, with a glareproofed sapphire crystal and case back, a screw-locked crown and water resistance to 50 m. The 18-carat white gold bracelet, model 1220BC, is integrated into the case and closes with an AP folding clasp. Audemars Piguet no longer lists the 15412BC.ZZ.1220BC.01 on its website; it still lists the sapphire and Swiss topaz versions.

How to read 15412BC.ZZ.1220BC.01

The 15412BC.ZZ against the other Double Balance Wheel Openworked models

Prices are Bizak & Co. listings read on October 19, 2026. All six are 41 mm Royal Oak Double Balance Wheel Openworked models with calibre 3132. The 15412BC.ZZ.1220BC.01 is the white gold version that keeps the slate grey dial and pink gold accents of the steel, pink gold and black ceramic models and adds a bezel of 32 baguette diamonds. The sapphire and Swiss topaz versions use the same white gold case and bracelet, set their hour markers with baguettes to match the bezel and have their own dial treatments (a rhodium-toned dial with a blue balance-wheel bridge on the SS, a grey inner bezel on the TO), and Bizak & Co. lists both well above the diamond version. Without stones, the steel 15407ST and the pink gold 15407OR are the lower-priced ways to the same movement and dial.

Checks before you pay the balance

• Reference and setting. The ZZ, SS and TO versions share one white gold case and bracelet. Check that the quote and any papers read 15412BC.ZZ.1220BC.01, that the bezel carries diamonds and that the hour markers are pink gold rather than gem-set.
• The 32 baguettes. Ask for daylight photos of the bezel from several angles to check that every stone is present, matched and free of chips, and ask whether any stone has been replaced, and by whom.
• Movement and service. The openworked dial and the sapphire case back show calibre 3132 from both sides. Ask for a short video of the watch running, a recent timing reading and the date and place of its last service.
• Papers and box. Ask for photos of the case back and of the papers and box that come with the watch offered.
• Bracelet length. Ask how many links come with the 1220BC bracelet, so it can be sized to your wrist, and for photos of the clasp.
