Vertically Mounted Balance Wheel
A balance wheel that stands upright, directly confronting gravity.
This vertically oriented design, carefully calibrated for vibration direction and weight distribution,
breathes new life into tradition — a reimagined heart of timekeeping.
Retrograde Small Seconds
A hand that glides forward with elegance,
then snaps back in a flash — a brief tension, a reset.
A rhythmic dance that turns seconds into a personal symphony.
Double Barrel 144-Hours Power resreve
Twin barrels generate a steady, powerful flow of energy.
With a six-day reserve, time unfolds at its own pace —
a quiet, enduring presence across each passing day.
Power Reserve Indicator
A visual breath of the watch itself.
This indicator reveals both the energy that remains
and the time already lived — the meeting point of mechanics and emotion.
