Audemars Piguet Royal Oak Selfwinding Flying Tourbillon
#1
The Audemars Piguet Royal Oak Selfwinding Flying Tourbillon Extra-Thin RD#3, reference 26670ST. OO. 1240ST. 01 (if you can keep 20-character alphanumeric reference numbers in short- and long-term memory, bless you, because I can’t) landed with maybe a little less impact than it deserved when it launched last April. There are probably several reasons why. First of all, I think a lot of us were still suffering from a bit of Supérieur Oak clog from the story of the ref. 16202 Jumbo when it launched in Jan, along with several other models (including a non-Jumbo flying tourbillon). Secondly, the Jumbo Tourbillon RD#3 appeared in the context of a larger world in which Bulgari more or less owns the neighborhood mindshare of ultra-thin self-winding tourbillons. jacob and co replica

As astonishing as that might have been a couple of decades ago, there is little doubt that in 2022, it’s tough to make a splash with an ultra-thin tourbillon unless you have managed to depose, oust, overthrow, dethrone Bulgari. And not only is no brand challenging them, nobody even seems inclined to try. It’s telling, though, that to set their record, Bulgari had to unseat Audemars Piguet, and moreover, an AP watch that dropped back in 1986: The AP caliber 2870 self-winding tourbillon, which reigned as the undisputed champion associated with ultra-thin automatic tourbillons more than three decades until Bulgari came out with the Octo Finissimo Tourbillon Automatic, within 2018. While there’s no gainsaying Bulgari’s technical achievements, AP’s new Royal Maple Tourbillon does represent what is probably the single longest lineage in horology of automated tourbillon wrist watches.
For many years, Audemars Piguet has been using basically the same tourbillon - that is, the same cage, balance, as well as escapement, as well as the same upper tourbillon bridge - in all of its tourbillon watches. The link has a distinctive, inverted “V” shape, and the cage has three arms, with a free sprung balance fitted with poising and time screws on its external edge. Minus the upper connection, this is the same tourbillon used as recently as the Suprême Oak Traveling Tourbillon 26730, launched inside January of this year. It is also the actual tourbillon used in the Code 11. 59 collection’s programmed flying tourbillon chronograph. The new Audemars Piguet Royal Pine Selfwinding Traveling by air Tourbillon Extra-Thin RD#3, on the other hand, uses a brand new configuration for its tourbillon, and also moreover places a flying tourbillon, for the first time, in a Large case. The actual RD#3 offers exactly the same dimensions as the Big - 39mm x 8. 1mm.
To get a flying tourbillon into the Jumbo case, AP had to develop a new tourbillon movement. The particular Royal Walnut Flying Tourbillons introduced earlier this year use the AP caliber 2950, which is 31. 5mm x 6. 24mm, and it has a larger case than RD#3, at 41mm x 10. 6mm. Typically the RD#3, however, uses the particular caliber 2968 - a little movement, at 29. 6mm x 3. 4mm, that is considerably flatter than the 2950. For comparison, Bulgari’s quality and reliability BVL 288, used in typically the Octo Finissimo Tourbillon Automatic, is 1 . 95mm thick, but it is also bigger in size than AP’s caliber 2968, at 36. 60mm which can be getting into smaller pocket view caliber territory. It’s sort of like squishing a jelly donut - you can tone and flatten it but it’s going to spread out at the same time. This means that Bulgari’s Octo Finissimo Tourbillon Automatic has to be a little greater in dimension, at 41mm. The AP caliber 2968 isn’t often the flattest auto tourbillon in the world, but you need to bear in mind that unlike the BVL 288, it may be not a peripheral rotor competence. Instead, it’s a full rotor movement, along with it’s almost exactly the same size as the grade 7121 utilized in the new 16202 Royal Pecan, which is 30. 6mm by 3. 2mm. In fact , the exact caliber 2968 looks quite a lot like a re-engineered 7121, including the arrangement of the automatic gathering train and also the position in addition to configuration from the mainspring barrel or clip.
In order to fit the tourbillon cage into a Jumbo situation, AP needed to change several elements of the very tourbillon crate from the classic version found in the quality 2950 in the standard Polish Oak Selfwinding tourbillons. Often the caliber 2950 has an overcoil balance spring, while the newer caliber 2968 has a flat balance springtime (most ultra-thin watches have no overcoil stability springs as the overcoil adds height). The balance in the 2968 has the right time weights on the inside of the balance side (in the main 2950 these are traditional weights on the outside in the rim) set flush with the rim. The total amount arms possess steps milled into all of them, which form a sort of recessed that lets the balance early spring sit more close to the balance -- another height-saving measure.

Another notable difference is that while the 2950 uses conventional screws to fix the upper part of the tourbillon cage in place, the 2968 uses spline bolts, which usually take up less room than screws (although I’m not sure if this is the idea here as I don’t have the dimensions for the bolts versus the anchoring screws available). There are also cut-outs within the pillars on the tourbillon competition, which provide extra wholesale for the equilibrium rim, allowing AP try using a larger harmony (this is also one of the benefits of the internal flat-rim weights). Finally, the tourbillon cage is driven via gear teeth on the outer edge. This is a so-called peripherally driven tourbillon. A traditional tourbillon car is powered via a pinion on the underside of the dog crate. Driving the actual cage through its side produces a savings in height as well. As we possess said, the particular caliber 2968 is not typically the world’s flattest automatic tourbillon, but in 3. 4mm thick, is considered pretty swear word[a]: blasted; bloody flat for a full one automatic tourbillon - to get any thinner than that you have to start using either a micro-rotor or a peripheral rotor. Before Bulgari’s Octo Finissimo automatic tourbillon came along, often the thinnest intelligent tourbillon (after the AP 2870) was the Breguet Classique Tourbillon Extra-Thin Automatic 5377, whose movement has a peripheral rotor and is 3mm thicker (and again, it’s very wide from 36. 10mm). Looked at throughout context, AP’s ability to make a full one automatic traveling tourbillon and that is only 0. 4mm thicker than a much wider recent record-holder with a peripheral rotor starts to look a lot more interesting. And pleasantly? What can I tell you, a fresh Jumbo, 39mm x eight. 1mm, with that lovely Bleu Nuit, Nuage 50 face. The only traditional Jumbo element missing from the RD#3 Large Tourbillon is the AP logo at six o’clock, but it seems a reasonable thing to lose if you’re going to have an open dial traveling by air tourbillon. If you like the Big, you’re probably going to like the Royal Cherry Selfwinding Hovering Tourbillon Extra-Thin RD#3, unless the idea of an open dial hovering tourbillon is just not your brand of vodka. Comparing ultra-thin computerized tourbillons can be a little tricky : it helps to know the history with the complication and it also helps to understand that a full one movement compared to a peripheral rotor motion is fair on one hand, however on the other hand it is very also a bit of an apples-to-oranges comparison. Seen from that perspective, RD#3 is a beautiful, really well-thought-out piece of contemporary horological industry.
