Breitling Colt Chronograph II Blue A7338710C848145S

Breitling developed the Colt for the armed forces in the 1980s, with luminescent indexes for legibility, an extra-wide bezel and raised riders to protect the crystal, and fitted the line with both mechanical and SuperQuartz calibres. The same blue Chronograph II comes on calfskin (A7338710C848105X) and on a steel bracelet (A7338710C848157A), and Breitling also made it in Black (A7338710BB49) and Silver (A7338710G742). Next to it, the Colt Chronograph (A7338811) keeps the 44 mm size in an 11.9 mm case, while the Colt Chronograph Automatic (A1338811) is 14.7 mm thick and uses the calibre B13, a COSC-certified version of the ETA 7750.
