Product Details
Breitling’s versatile Chronomat in a limited-edition collaboration with Giannis Antetokounmpo. Limited to only 2,000 pieces, the Giannis Antetokounmpo Chronomat collection combines our timeless craftsmanship with the Pro Basketball Player’s easygoing style. It features green colourways chosen by Giannis himself while preserving classic Chronomat design elements such as the “Rouleaux” bracelet—in metal or rubber—and raised rider tabs at the 15-minute marks. Note the central hand’s counterweight bearing the athlete’s initials “GA” and the basketball outline on the running seconds counter of the Chronograph—a nod to his profession and passion. The limitation, “One of 1750” for the 40 mm stainless-steel Automatic GMT or “One of 250” for the 42 mm 18 k red gold Chronograph is engraved on the caseback. Each watch comes in a special box with a note from Giannis. A watch enthusiast, Giannis has also designed his own one-of-a-kind Chronomat featuring a green inverted-panda dial and Eastern Arabic numerals—though you might only catch a glimpse of this unique piece courtside. The Chronomat Giannis Antetokounmpo collection is meant for those who can relate to the basketball MVP’s power, precision, and performance—traits that have everything in common our timepieces.
