A conventional mainspring’s force drops as it unwinds. It’s a law as old as watchmaking itself. But laws were made to be understood, then transcended. The Gravity Equal Force Ultimate Sapphire Purple reimagines the horological energy transfer through a constant-force mechanism that optimizes the non-linear power curve inherent in traditional mainspring systems. Put more simply: it breaks the laws of traditional watchmaking with radical micro-engineering.
