About the Mirrored Force Resonance family
The Mirrored Force Resonance, first shown in 2019, has two balances linked by a patented resonance clutch spring so that they settle into the same rhythm, which improves stability. Both balances are visible on the dial side.
The catalog lists versions in steel, including a red guilloché dial and a blue Manufacture Edition. Several colour versions share the movement, so dealers quote the dial and check the papers.
