Zeno OS Pilot 8524‑A1 – Oversized Swiss Automatic with Pilot Heritage
The Zeno OS Pilot Men’s Automatic 8524‑A1 channels classic aviator aesthetics with modern Swiss reliability. Its imposing 47.5 mm stainless steel case (~15.5 mm thick) and exhibition case back make a bold impression without compromising wearability. A robust hardened mineral crystal protects a highly legible black dial framed by silver-tone Arabic numerals and luminous hands, ensuring readability at a glance.
Under the hood lies a dependable Soprod/ETA-derived automatic movement, delivering approximately 40 hours of power reserve. The integrated date window at 3 o’clock and 24-hour markers enhance daily utility.
Attached is a high-quality black leather strap (approx. 21 mm wide, 8 inches long) secured via a pin-buckle clasp. Despite its rugged pilot styling, this model retains a 30 meters (3 ATM) water resistance—more than enough for daily wear and light moisture.
