Constance's own movement series ultra-thin tourbillon high temperature glaze enamel watch
Frederique Constant Manufacture Tourbillon Grand Feu
5th Anniversary Edition of Plan-les-Ouates Factory in Geneva
Constance unveils its new Manufacture Tourbillon Grand Feu. Watch with hand-glazed dial, is a rare treasure. Currently, only a handful of watchmakers can make real enamel dials by virtue of their traditional skills.
Glazing is an ancient technique that involves applying fine tinted glass to a metal plate and placing the colored metal plate in an oven to melt the glass. This glazing process creates a beautiful, shiny, thick layer.

Only a small number of glazed metal plate can withstand the fire over 900 degrees Celsius, made of uniform surface. If mixed with powder, there are some slight flaws or dust in the support plate, which can cause the entire dial to collapse and need to be glazed again.

Homemade tourbillon movement
With an award-winning home-made heart movement, Constance completely refines the tourbillon in its own factory and has the following features:
Silicon escapement wheel and lever
Smart weight balance
28'800 BpH rapid shock
Movement and case carved engraved independently number
Silicon escape wheel:
Silicon escapement wheel and the control rod has the following three major advantages:
Improve: You can operate without oiling
advantage:
1. To eliminate the problem of oil fade and dry.
2. The escape wheel is not oiled, to avoid the risk of oil contamination to other components of the movement.
Improvement: Material is very light (low inertia)
Advantages: Each watch operation will push and stop the escapement wheel. This lighter silicon escapement has lower inertia and better energy efficiency.
Improvement: Good friction performance
Advantages: Reduce friction and reduce energy consumption, energy required for the movement is also reduced.
This silicon escapement has advantages over the usual three escapement wheel of the three major advantages for the tourbillon mechanism is particularly useful. Silicon escapement wheel weight reduction, and better anti-friction performance, can continue to enhance energy efficiency. Therefore, the amplitude of the dials and dial positions of the Constance flywheel equipped with silicon escapement wheel exceeds 300 degrees. Even in the crown down position, the amplitude is also more than 275 degrees, the performance is clearly superior to other advanced tourbillon. [page]

Intelligent weight compensation balance device
Constance's tourbillon contains 80 separate components. Each component is designed to be as high as 1-2 microns (0.001-0.002 mm) with the highest endurance and is based on the ultra-precision CNC instruments from Constance's workshop at Plan-les-Ouates. These refined next-generation instruments and X and Y axes endure up to 1 micron and the Z-axis to 2 microns. Although extremely accurate, it is impossible for each individual component to achieve 100% symmetrical weight distribution.
To make an accurate touring tourbillon, symmetrical weight distribution is paramount, and Constance's solution is to put a patented "smart screw" system on the outside of the Tourbillon. Tourbillon face with intelligent screw system installed on the main frame wheel. After that, the skilled artisan should balance the balance of the tourbillon center by adding or changing small metal rings under the two screws in the main frame. In general, watchmakers need eight hours to fine-tune the rings until the weight of the entire tourbillon reaches its perfect balance.

Rapid shock
The Constable Tourbillon runs at 4 Hertz and the balance wheel beats 28,800 beats per hour. As a result, the balance wheel of the Constance Tourbillon oscillates 28,800 times per hour, whereas the gear train advances 691,200 times per hour, beating more than 100 million flights every four years.
The best tourbillon on the market runs at 3 hertz. The "Bourdon Hourly" (BpH) speed makes the Tourbillon movement more accurate. The higher the amplitude, the movement can be further reduced by the impact of rotation. [page]

Separately numbered
Each Constance Tourbillon watch Tourbillon frame engraved with an independent number, indicating that the limited production of 188. The tiny roof of the Tourbillon stand will be added with the serial number when manufactured by Constance CNC Instruments. The numbering on the shelves matches the limited number of the case, highlighting the unique and collectible value of every Constance tourbillon.
