Introducing Werk 7 – The Heart of Precision.
Discover Werk 7, our latest manufacture caliber with 70h power reserve, variable inertia regulation, and extreme shock resistance.
Real innovation starts at the core.
At Fortis, we build from the inside out.
Werk 7 is our new manufacture caliber — developed from the ground up to deliver lasting accuracy, high resilience, and a 70-hour power reserve.
At its center: a variable inertia regulation system, based on a principle first introduced by Patek Philippe.
It allows for ultra-precise adjustment — without the fragility of traditional regulator pins. The result: a movement that stays precise even under pressure.
To reinforce its robustness, Werk 7 features an oversized balance bridge with two-point fixation.
Greater shock resistance. More long-term stability. Built to endure.
Every element in Werk 7 is built with purpose.
No distractions. No excess.
Just function, durability, and mechanical focus — down to the last detail.
The New Standard of Fortis Movements
Werk 7 sets the tone for what’s next.
Clear lines. Pure engineering. Timeless performance.
This is the beginning of a new era at Fortis.
And it starts here.
