Breguet is a manufacturer of luxury watches, founded by Abraham Louis Breguet in Paris in 1775. Currently part of The Swatch Group, its timepieces are now (since 1976) produced in the Vallée de Joux in Switzerland. Breguet is one of the oldest surviving watch-making establishments and is the pioneer of numerous watch-making technologies, the most notable being the tourbillon, invented by Abraham Louis Breguet. Breguet has recently introduced a line of writing instruments as a tribute to writers who mention or feature Breguet watches in their works. Breguet watches are often easily recognized for their coin-edge cases, guilloché dials and blue pomme hands (often now referred to as 'Breguet hands').
