What to know

Lune Exacte extends Strehler’s ultra-precise moonphase work by adding a moon-age indication readable in three-hour increments. A rotating Vernier scale communicates the moon’s age rather than treating the complication as a purely pictorial aperture.

The manually wound movement combines the moon display with Strehler’s remontoir d’égalité. It runs at 3Hz, uses 184 components and 25 jewels, and offers a stated 78-hour power reserve from twin barrels. The quoted deviation is one day in two million years.
