At SIHH 2016, Audemars Piguet launched the Royal Oak Double Balance Wheel Skeleton Watch. With a diameter of 41 mm, this new version is equipped with a hollow dial (hence the name hollow dial), and its internal calibre 3132. This movement is the world's first double balance escapement. Audemars Piguet is available in stainless steel (reference number 15407ST.OO.1220ST.01) and rose gold (reference number 15407OR.OO.1220OR.01). chronosale.co
The new Royal Oak Extra-Thin is equipped with the 5021 movement and was first introduced 50 years ago. It started in 2120 (exactly the same as 2121, but without a date wheel), and was created by Jaeger-LeCoultre in 1968 at the request of Audemars Piguet, Hublot Spirit of Big Bang replica Watches.
These three brands all use 2120 and 2121, although they are now exclusively owned by Audemars Piguet, which is produced in-house. replica watches luxury
Compared to the previous Royal Oak Chronograph, the new model has some subtle but important differences. The two small dials of the chronograph have larger hours and minutes for easy identification. The continuous second hand at 6 o'clock has a smaller scale, which is logical because all you need to do is to see if the watch is running and to synchronize it when setting the time. replica watches swiss
This change in the size of the sub-dial causes the date window to move slightly clockwise, so it is no longer centered between the 4 o'clock and 5 o'clock batons. The hour markers are getting shorter and shorter, so there is more space for more SuperLuminova. The counterweight of the chronograph second hand also has some luminous paint.
