Elegance in the Details
Despite the functionalist inspiration, there are subtle elegant details, such as the treatment of the surfaces, alternating between brushed and polished finishes.

THE MOVEMENT
The engine of this watch is a Swiss Sellita SW510 Top Grade movement. Top Grade indicates that the manufacturer imposes the strictest tolerances and the highest care during production.
This movement originates from the Sellita SW500 project, an “integrated” chronograph movement based on the famous Valjoux 7750, one of the first automatic chronographs. The design of the 7750 dates back to 1973, and unlike other automatic chronographs on the market, such as the Zenith El Primero or Breitling, the 7750 was less refined but significantly more robust, a characteristic that made it…
Transformed this movement into an icon. The 510 is an evolution of the SW500, with the main difference being the arrangement of the subdials, which changes from a 12-3-6 layout to the more classic 3-6-9. This chronograph features a “coulisse” escapement, meaning the chronograph functions are driven by levers that move a cam back and forth, alternately starting, stopping, and resetting the chronograph. This system is less complex than the so-called “column wheel,” but it offers a significant advantage in terms of robustness, simplicity, and reliability.

This chronograph has a “coulisse” escapement, which means the chronograph functions are guided by levers that push back and forth an oblong cam, alternately starting, stopping, and resetting the chronograph. This system is less elaborate than the so-called “column wheel,” but it offers a significant advantage in terms of robustness, simplicity, and reliability.
The Controls
In order to minimize the risk of error, rather, to maximize the chances of identifying and correcting it, each watch undergoes numerous extensive checks.
The movement is tested by the manufacturer according to the specified standards and tolerances. When the movement reaches our control laboratory, it is kept running for at least 7 days. The movement is then “cased,” and the watch is completed and closed. At this point, the assembled chronograph undergoes another series of tests. If the watch does not meet the established standards, the technician will adjust the movement, if possible, or replace the entire movement.
Each watch is accompanied by a control document that includes the readings from the chronocomparator.
THE COLLECTION
Dedicated by those who fly to those who fly, each watch combines the needs of pilots with
a search for elegance. Powered by a Swiss movement, forged from the steel of an F104 Starfighter’s turbine.
