Breguet was well known for making high quality watches
and carriage clocks, he made very few precision table
regulators, which makes this especially rare.
remontoire provides a more constant and gentle power
to the escapement. It consists of an endless chain passing
over two toothed pulleys on the movement and supporting
two weights suspended on grooved pulleys.
first weight supplies the power directly to the escapement
and each time the clock strikes, the spring barrel re-winds
the weight and turns the second toothed pulley with
the second weight acting as a counter weight.
During his life, Abraham-Louis Breguet held the position
of Clockmaker to the French Navy and became a Chevalier
de la Legion d'Honneur. He was a member of the French
Board of Longitude, a body set up to assess the quality
of timekeepers made to find longitude, and was also
a member of the French Royal Academy. In his time, Breguet
was a pioneer in the design and making of watches.
from a series of marine chronometers, Breguet's finest
achievements in the area of clocks were a group of silver-cased
hump-back carriage clocks, and clocks known as pendules
sympathiques, designed to automatically wind and set
the owner's watch to time at night.
