Introduction
Standing as a remarkable testament to aviation-inspired watch design, the Zenith Type 20 Blueprint ref. 03.2435.679 forms part of Zenith's iconic Pilot collection which merges the brand's storied history with innovative craftsmanship. Paying homage to the golden era of aviation, its design encapsulates the adventurous spirit of early 20th-century pilots through its large 45mm stainless steel case and onion-style winding crown that allowed pilots to turn the crown while wearing flying gloves. The "Blueprint" aspect of its name is vividly represented on the blue dial, showcasing technical blueprint details that highlight the intricate design and engineering that go into the ref. 03.2345.679’s dial through the numerous measurements that are shown on the dial. Powered by the cal. 679 automatic movement, the ref. 03.2345.679 ensures precision and reliability, with a power reserve of approximately 50 hours. The dial, detailed with technical blueprint lines, remains legible thanks to luminous hands and numerals, ensuring clarity in all conditions. Limited to just 250 pieces, as referenced by the plaque on the 9 o’clock side of the mid-case, this timepiece is not just a functional tool but a piece of art, embodying the spirit of aviation and Zenith's meticulous craftsmanship.
