**Abraham-Louis Breguet** was a Swiss watchmaker. He is regarded as the most important watch maker and inventor in the history of time measurement.

===== Born in Neuchâtel, Switzerland =====
Abraham-Louis Breguet is born on 10 January [[1747]] in the Swiss town [[Neuchâtel]] (German Neuenburg, formerly Neufchâtel), which then belongs to the Kingdom of Prussia.

He completes an apprenticeship with his stepfather Joseph Tattet in Neuchâtel and from about [[1763]] in Versailles. He then works in Paris, probably with Ferdinand Berthoud and [[Lépine, Jean Antoine|Jean Antoine Lépine]], before he opens his own workshop there in about [[1775]]. Initially the focus is on the [[finissage]] of foreign [[ebauche movement]]s, but soon follows the production of [[pocket watch]]es with his own movements, in the style of [[Lépine, Jean Antoine|Lépine]].

In [[1784]] he is accepted into the guild as a master watchmaker and in [[1785]] he becomes purveyor of King Louis XVI. After the beginning of the revolution, in [[1793]], Breguet fled from France back to Neuchâtel. During a stay in London, contacts were made ​​to the chronometer maker [[Arnold, John|John Arnold]], from which developed a friendship. In [[1795]] he returned to Paris.

In [[1808]] his son [[Breguet, Louis|Louis]] enters the firm as a partner and continues it after Breguet's death. Since then the manufacture is named „[[Breguet|Breguet et fils]]".

===== Significant inventions which make watch history =====
In addition to plenty of quality and also highly complicated [[pocket watch]]es we owe to Breguet also many important inventions, such as the improvement of the [[automatic]] winding ([[1780]]), the free [[escapement]] "échappement naturel", the "Parachute" [[shock protection]] of the [[balance staff]] ([[1790]]), the ruby [[cylinder escapement]], the [[tourbillon]] ([[1801]]), and the bent terminal curve of the [[flat hairspring]] - later named [[Breguet hairspring]] after him ([[1795]]).

For the sister of Napoleon I. and Queen of Naples, Caroline Murat, Breguet built a watch that could be worn on the wrist, and thus created probably the first [[wristwatch]] in the world. It was ordered in [[1810]], paid for in [[1811]] and delivered in [[1812]] a very thin, oblong watch with [[repetition]], additionally equipped with a thermometer and connected with a bracelet of hair, in which a golden thread that was woven in. Caroline later bought another twelve of watches from Breguet (including eight more with repetition) and thus enabled him to experience an important economic upswing.

Abraham-Louis Breguet died on 17 September [[1823]]. The funeral took place one day later at the cemetery Père Lachaise.

===== The watch manufacturer Breguet =====
The spirit of Breguet lives on today in the high-quality watches, which are manufactured at the [[Breguet|Breguet Montres SA]] named after him, because the appearance of these watches has still the same basic features, based on Abraham-Louis Breguet classic, often [[guilloche]] dial with Roman numerals, Breguet hands and [[cannellated]] case in solid [[gold]]. Not to mention the top quality, which puts the models available today into the class of the most expensive watches.
