Audemars Piguet Royal Oak Offshore Music Edition
Beat, tempos, rhythms are all about timing, so it comes with little surprise how you could link watches to music. Plus if we’re talking about Audemar Piguet, then we can trace their contribution to audio, back to their mid-19th century chiming watches. Or in current times we can focus on all the contemporary artists known to wear AP’s, plus their partnership with the Montreux Jazz Festival. No matter how you flip it the new Royal Oak Offshore Music Editions are a hit.These watches come in different materials, sizes, and with distinct caliber movements housed inside. They are available in either titanium, 18k white gold (37 & 43mm) or black ceramic (only 43mm), all with vertically brushed surfaces and polished accents.On the flip-side they all have sapphire exhibition caseback that allow a view into the inner workings of the mechanical movement. Despite housing two distinct calibers they’ve both been decorated with satin brushing, circular graining, a Côtes de Genève finish, and an oscillating weight made of 22k pink gold with black NAC coating.
Other cool music themed elements come in the form of knurled textured studs that look like jack plugs.
Surrounding the setting-crown are crown guards sculpted to appear as faders on a mixing console.
Mounted to the cases is the iconic “Royal Oak” octagonal shaped bezel in a matching alloy; but in common all these options have exposed 18k white gold screws. 
In contrast, a big difference is that water-resistance can reach up to 50 meters (164 feet) for the 37mm cases, while the 43mm options can resist up to double that at 100 meters (328 feet).
Except for the 18k white gold models that feature a gemstone studded bezel. The ten colors chosen to recreate an equalizer were recreated with: rubies, peridots, tsavorites, green, blue and orange sapphires.
A technique known as the “harmony cut” was employed to inject more sparkle into these precious minerals.
Time is exhibited on a music theme dial designed to mimic the colored bars on an equalizer. The backdrop is still very much the iconic AP Petite Tapisserie” motif, which is a pattern of small squares, obtained thru a hand guilloché. But, in this edition several squares are color coded to seem like the beat sequence on a stereo equalizer. 
This musical color-scheme is further enhanced by all the extra glitter and sparkle, brought about by the blue aventurine tapisserie dials, seen on the white gold models.
All options have a sloped flange with a printed 60-minute track. The central hand and applied hour index markers match each cases alloy, but in common they’ve all been fitted with a luminescent coating, for an enhanced legibility.
Audemars Piguet Royal Oak Offshore Music Edition
The “Audemars Piguet Royal Oak Offshore Music Edition” 37mm options are powered by self-winding mechanical movement, caliber 5909 with 29 jewels and 28,800 vph. This is the first time an automatic hours, minutes and seconds movement has been integrated inside a 37mm by AP. Caliber 5909 is based on caliber 5900, which had replaced caliber 3120, (when it first appeared in 2012) due to its advantage of being thinner (3.9mm versus 4.2 mm) and offering a higher frequency than its predecessor (4Hz versus 3Hz). Power reserve can last up to 60 hours, when fully wound.
While the 43mm models are powered by caliber 4309 with 32 jewels and 28,800 vph. Power reserve can last up to 70 hours, when fully wound.
Mounted to the watches can be a blue rubber strap with “constellation” texture, or just regular stealth black rubber strap.
They all come with three additional interchangeable rubber straps in turquoise, green, and yellow. These are limited editions with only 500 per edition in titanium and 250 in black ceramic. The white gold options aren’t limited, but require setting up an appointment at your nearest AP boutique because it is “Price on Request”.
