The Breguet Classique Chronograph 5287 was introduced earlier this year in either an 18K rose or white gold case measuring 42.5 mm in diameter. It is shown with an 18K gold silvered dial with four engine turned patterns (also available in a black dial). Inside is a manually wound caliber (previously called 2310) designed in the 1940s by Albert Piguet at Lémania, where it was called caliber CH 27. At the time, it gained a reputation for its endurance and reliability. And now, Breguet decided to introduce the reference 5287 to honor the legendary Lémania based movement. The modern version, called caliber 533.3, has received a redesign, visible through the clear case back. Needless to say, the finishing of the movement is superb.
