Stronger. Sharper. Tougher: Werk 7

Werk 7 marks a new era at Fortis. With a 70-hour power reserve, this beast delivers unwavering reliability no matter the conditions. Within the Variable-Inertia Regulation, the rate of the watch is adjusted by moving small weights on the balance wheel rather than changing the length of the hairspring. This maintains the true center of oscillation, leading to more consistent timekeeping and less susceptibility to external influences. The Double-fixation of the balance and an oversized bridge form the foundation of Werk 7’s unparalleled robustness.
