*LNOS* 1975 Breitling TransOcean Chrono-Matic (Ref. 2129) Blue Dial "Cal. 12"

The "Chronomatic" calibre 11 movement is argued to be the first, if not one of the first automatic chronograph movements ever produced. In the 1960s many major watch brands were competing to create the first automatic chronograph movement. Rivalries and tensions were high between the Buren group, Seiko, and Zenith. The Breitling / Hamilton / Heuer joint effort to create the automatic chronograph is said to have been secretly named Project 99. Once the Chronomatic movement was created, several subsequent variations followed, including the cal. 12 which features a more accurate 21,600 bpm. Breitling housed many of their chronographs with this groundbreaking movement, including this superb ref. 2129 This "LNOS" or like new old stock example is exactly as described, showing no actual signs of previous use whatsoever. Apart from a few superficial storage marks, the entire watch is essentially in brand new condition.  Stock # BRLTOCM2129 Brand Breitling Style TransOcean Chrono-Ma
