Editor's Notes

"It was the watch that boldly proclaimed Breitling was staying absolutely true to its roots," says CEO Mr Georges Kern of the 'Chronomat' reference that was re-designed in 2020. Initially launched in 1984 - when quartz movements were dominating the market - this automatic, COSC-certified 'B01' reference has been built in Switzerland from polished stainless steel and features original design details, including a rotating bezel with signature rider tabs and integrated Rouleaux bracelet. The hands are coated with Super-LumiNova® to ensure legibility.
