Breitling Colt watches

The Breitling Colt is Breitling's steel sports watch on a diver's template: a plain, legible dial under a rotating 0–60 bezel. It began as a military watch, designed with reliability and legibility first, and the line paired COSC-certified automatic movements with high-precision quartz calibres.

Most Colts carry their size in the name: the Colt 33 and Colt Lady at 33 mm, the Colt 36, the Colt 41 Automatic and the Colt 44. Of the two 44 mm models, the Colt 44 Automatic is the slimmer at 11.25 mm, against 14 mm for the Colt 44. The Colt Lady and Colt 36 also come with mother-of-pearl dials and gem-set bezels in place of the diver's bezel, the Colt Oceane is a 33.2 mm ladies' model, and the Colt GMT sits at 40.5 mm.

The chronographs start with the 41.1 mm Chrono Colt and move up to the 44 mm Colt Chronograph and Colt Chronograph II. The Colt Chronograph Automatic (A1338811) measures 44 mm and 14.7 mm thick and carries Breitling's calibre B13, a COSC-certified version of the ETA 7750, under a unidirectional diver's bezel. It also came as a Blacksteel model (M1338810) and as Japan Special Editions in black and blue.

The Colt Skyracer, shown at Baselworld 2017, swaps steel for Breitlight, a material said to be three times lighter than titanium and more scratch-resistant than stainless steel. Its 45 mm case, 13.15 mm thick, holds the thermocompensated SuperQuartz calibre Breitling 74 and is water resistant to 100 m. Breitling also made it as a Patrouille Suisse edition (X74320B5).
