Gravity Equal Force Ultimate Sapphire Purple

CHF 27'500

An unprecedented feat of micromechanical ingenuity demonstrated through a singular design, the Gravity Equal Force with a grey transparent sapphire offset dial and guilloché purple movement plate by Kari Voutilainen is the first automatic watch endowed with an equal force transmission integrated directly in the mainspring barrel – on full display from the dial side. The result is consistent power transmission to the regulating organ, ensuring unwavering precision throughout the watch’s autonomy.

In the quest for superior chronometric performance and more consistent isochronism, the Gravity Equal Force distinguishes itself as the first-ever watch to features a stop-work declutch mechanism in an automatic winding movement – a patented mechanism by Armin Strom. Incorporated directly within the mainspring barrel, this ingenious solution provides more consistent power delivery to the regulating organ at every stage of the movement’s autonomy.

Befitting its innovative, highly structural and superlatively hand-finished movement, the Gravity Equal Force’s design is coherent – inside and out. Familiar forms take on new shapes and proportions that highlight the mechanical marvel within, constructed with a slim bezel and lugs profile that allows as much depth and detail as possible from the architectural movement to be admired from all angles.

The Gravity Equal Force Purple adds even more visual depth to an already architectural watch with the inclusion of a grey tinted transparent sapphire dial, revealing even more of the groundbreaking movement. The signature three bridges are coated with dark grey ruthenium, fixed atop a purple guilloché engraved movement plate handcrafted by renowned independent watchmaker Kari Voutilainen.
