Breitling. A large, rare and very fine 18K gold automatic chronograph wristwatch with date, champagne dial and pulsometre scale

According the Archives of Breitling, the present watch was manufactured in 1969 and fitted with a Bueren 11 calibre.

Consigned in impressive new-old-stock condition, this wristwatch is without doubt a page in the history of watchmaking: Cal. 11, developed by Breitling in association with other manufacturers, is the first automatic chronograph movement ever produced. To incorporate into the movement a microrotor and the chronographic functions was a groundbreaking innovation, which however came at a price: the crown had to be moved to 9 o' clock. Being this calibre an automatic one - and with a dead angle of only 11 degrees - the modification was deemed acceptable by the manufacturer. The aesthetic appeal of the piece combined with the outstanding condition and the historical importance of the model make this wristwatch a nearly unique occasion for the true watch connoisseur.
