About this watch

The Zenith Defy El Primero 21 is a stunning masterpiece that perfectly marries art and engineering. With its unique design and cutting-edge technology, this watch isn't just a tool for telling time; it's a statement. The rose gold case exudes luxury and elegance, while the skeletonized dial reveals the intricate mechanics that make this watch tick. At the heart of the Defy El Primero 21 is the Zenith caliber El Primero 9004, which is nothing short of a technological marvel. This self-winding movement is capable of measuring time with astonishing accuracy, down to 1/100 of a second. The chronograph has a dedicated power reserve of 50 minutes, wound by hand, and features two balance springs made from high-tech 'carbon-matrix carbon nanotube composite.' With a diameter of 44.00 mm and a height of 14.50 mm, the Defy El Primero 21 is a substantial watch that commands attention. The case is paired with an exquisite alligator leather strap that enhances its luxury appeal and adds to the overall comfort.
