Editor's Notes

Zenith's 'Chronomaster Sport' references the '1969 El Primero A386' chronograph, which garnered fame for the extreme accuracy of its column-wheel movement. Powered by a chronograph-certified redesign of the original calibre, this new watch tracks time in tandem with a central hand that, circuiting the dial once every 10 seconds, indicates measurements to the nearest 1/10th of a second. It's crafted from stainless steel and features the '69 model's distinctive tri-colour subdials.
