Gravity Equal Force Ultimate Sapphire

The Gravity Equal Force is the world’s first automatic watch with constant force transmission, delivering stable power to the balance for unwavering precision. At its core is Armin Strom’s patented Equal Force Barrel paired with a stop-work declutch mechanism, ensuring consistent torque throughout the power reserve.

This execution features a grey-toned, off-center sapphire dial that opens a clear view into the finely finished manufacture movement beneath. The black movement plate is hand-guilloché by Kari Voutilainen, contrasted by dark grey ruthenium-coated bridges and rhodium-finished barrel and micro-rotor. Cool, architectural, and mechanically honest, it’s a defining expression of modern independent watchmaking.
