Description

As a self-winding watch with a minute-repeater striking the hours, quarters and minutes on demand, the new Marie-Antoinette has all the makings of a work of art. A full perpetual calendar displays the dates, the day and the months respectively at 2 o'clock, 6 o'clock and 8 o'clock. The equation of time at 10 o'clock proclaims the daily difference between solar time and the mean time told by watches. In the centre, the jumping hours -- invented by Breguet -- and the minutes are joined by a long independent seconds hand, while the small seconds are shown at 6 o'clock. The 48-hour power-reserve indicator 10:30 balances a bimetallic thermometer at 01:30. The self-winding, "perpétuel" movement comprises 823 outstandingly finished components.
