This manufacture calibre, co-developed with La Joux Perret, marks the beginning of a new era. At its core? A variable-inertia regulation system - originally developed by Patek Philippe - allowing for even finer adjustment than a traditional regulator. This ends up in higher precision and more robustness.

The Fortis Werk 17 Automatic Manufacture Calibre features a column wheel chronograph for enhanced reliability. 
It was tested in collaboration with the Swedish Space Corporation. The test consisted of a number of movements fixed on a gondola driven by a stratospheric balloon. Launched at the Esrange Space Center, the test-batch took off into the Stratosphere. After a flight time of 1.5 hours under the harsh cosmic conditions, the movements came back down and landed in the vast forest landscape of Finland. A year later in 2022 the movements have been successfully tested during a rocket campaign. For more details please visit the Fortis YouTube channel

A built-in alarm is a rare complication in a mechanical wristwatch. a one-of-a-kind movement. The F2001 calibre marks the first movement to combine the functions of an automatic chronograph and a mechanical alarm. It has been developed in collaboration with Paul Gerber. Two barrels ensure that the movement and the alarm operate independently of each other, making this micro-mechanics feat possible. The harmonious ring of the alarm sounds for about 25 seconds if neither interrupted nor switched off with the button at 8 o’clock.
