After 19 months of research and development, the amazing new planetary Blu- Majesty Tourbillon will astonish the watch-interested public. Its innovative technical solutions allow for a perfect incorporation of the tourbillon system into blu- Planet, the timepiece that is perhaps the blu- source du temps collection’s flagship model.

For quite some time, Bernhard Lederer has been deliberating the creation of his own tourbillon. Right from the beginning it was clear to him that the blu- Planet system would be the only one able to offer the unique look characteristic of all blu creations.

Lederer had been deliberating the tourbillon idea for more than three years, and a meeting with the independent engineer Willy Meier kicked off the fascinating blu-Majesty Tourbillon adventure. With Lederer's brilliant designing and prototype expertise and Meier’s knowledge of the industry manufacturing, the project was successfully sent underway.

What exactly is so new about blu- Majesty Tourbillon

First and foremost,blu-Majesty Tourbillon is different from any other watch in its appearance.

But almost equally as important, this tourbillon is not a karussel-style tourbillon so in evidence throughout the watch industry today. It is a half-flying tourbillon, meaning it is a so-called flying tourbillon with an opposite support, making it visible without obstruction but retaining stability. A karussel is driven by the third wheel, whereas a true tourbillon is driven by the fourth wheel (which also drives the second hand), making it far more delicate.

The blu- Majesty Tourbillon turns on three separate axes, beginning with the dial that revolves around its own axis in a twelve-hour period. Inside that mechanism, there is a one-hour tourbillon, the cage of which simultaneously acts as the extra support for the flying one-minute tourbillon whose cage contains the escape system and which is sent on its twelve-hour orbit around the dial.

In other words, the blu- Majesty Tourbillon contains three cages fixed along three parallel axes. A real eye-catcher is that two of the three axes are linearly arranged, keeping them on the same plane:

The half-flying one-minute tourbillon is literally placed inside the flying one-hour tourbillon.

And both of these are arranged eccentrically within the third flying tourbillon, one of a twelve-hour variety.

The movement was designed and assembled entirely in blu- source du temps’s workshops; blu – source du temps collaborated on the extensive realization of the project intensively with Meier and his team. The fact that blu – source du temps was the driving engine behind the project allowed all parties involved to keep all the technical needs of this very special triple cages tourbillon system in the forefront right from the beginning.

An important characteristic of this movement: its source of energy

The extra energy needed to drive all of these delicate functions is supplied by twin, serially operating spring barrels.

These are placed right on the underside of the base plate, utilizing its entire surface, space that is normally reserved for the escapement and gear train. The escapement is now placed within the cage of the one-minute tourbillon, and the gears have been positioned in a more linear arrangement, necessary to move all of the tourbillons as well as the rotate the dial. These functions are logically all located on the dial side of the movement. All in all, a pretty perfect setup that can easily incorporate an extra spring barrel for the extra power and stability needed.

More stability and aesthetics with a larger balance

Another element that sets blu- Majesty Tourbillon apart from the rest is the size of its balance wheel. The oscillating golden wheel is visible slowly and elegantly swinging in the large tourbillon cutaway with a diameter of 15.6 mm.

Choosing a lower speed of 2 oscillations per second was done to purposefully retain the aesthetics of the entire object and keep it visible, emphasizing the harmony between the timepiece’s functions and its proportions.

blu does not chase radio-controlled precision, but rather prefers to retain the details necessary for deep personal emotion and cogitation.

Returning to 2 Hertz is like coming back to the source of time and bringing out the celebration to Königs Discipline

Underscoring blu – source du temps’s motto: Time is not at the center of our lives – we are.
