The 103 Diapal instrument chronograph is designed to resemble the cockpit instruments that pilots use. Its movement is Valjoux 7750 automatic that performs 28 800 vibrations per hour and has 25 bearing jewels. A dehumidifying capsule protects the dial from fogging. Additional useful functionalities include a second time zone, a captive pilot's bezel measuring elapsed time of up to 60 minutes, electroplated and UV-resistant dial, a date window at 3 o'clock, luminous dial elements, transparent case back and scratch-resistant sapphire crystal glass with anti-reflective coating.
