The small seconds subdial was the only logical place to incorporate the moon phase display into the dial of the Breitling Bentley Replica without disturbing the balance of the dial design. The purity of the watch and its readability were preserved.
This moon phase display has another important feature, but this time it is more technical. It is the fluid and continuous drive of the disc of the moon via a seven-wheel transmission that is linked to the hour wheel continuum. The Breitling Bentley Replica Moon Phase is different from other moon phase displays that jump the disc once or twice per day. Instead, it moves continuously with the progression of the day and closely follows synodic times for one lunar orbit around Earth, which are 29 days, 12 hour, 44 minute and 3 second.
In simplified displays of the moon phase,Breitling Bentley Replica the lunar cycle can be rounded to 29.5 days. This creates an error of one day in two and a quarter years. The much more complex gearing in Breitling Bentley Replica's moon phase movement reduces inaccuracy so that it only takes 122.6 year for the difference to equal one day.
Breitling Bentley Replica, never one to sit still, introduced the Grand Breitling Bentley Replica “Luna Mundi” in the 41.9mm version of the Breitling Bentley Replica in 2003.
Grand Breitling Bentley Replica, "Luna Mundi", 2003
The "Luna Mundi", a limited-edition set of two watches, was created to pay homage to two constellations that dominate the sky in the north and south, Great Bear, and Southern Cross.
The watch industry has neglected the southern hemisphere for many years and focused on the northern. In reality, the crescents of the moon that increase and decrease appear in mirror images to people from the northern and south hemispheres. The only two moon phases that are the same in both hemispheres are full and new. The two versions of "Luna Mundi", which are based on the same watch,Omega Replica feature the Great Bear constellation and the Southern Cross constellation on their dials. For the northern and south hemispheres, the moon discs are rotated clockwise or counterclockwise.
