Description

MECHANICS FIRST. ALWAYS.

Precision, architecture, and artistry converge in the Gravity Equal Force Ultimate Sapphire Rose Gold. Encased in solid 18K rose gold, the sculptural ASB19 movement features Armin Strom’s patented stop-work declutch mechanism with a Geneva cross—ensuring constant force to the balance wheel for the full 72-hour power reserve.

A floating sapphire subdial offers an unobstructed view into the beautifully hand-finished movement, decorated with guilloché by Kari Voutilainen. The result is more than horology—it’s harmonic tension in three dimensions.

Designed for those who value science over spectacle. Limited to 20 pieces per year.
