The CA4660-61A has gained quick popularity for being a "Compact Tool Watch." Most pilot watches with slide rules are notoriously large, but Citizen managed to fit all the professional functionality into a 40mm case. It is often compared to the Seiko "Flightmaster" or "Speedtimer" but with the added benefit of Eco-Drive (solar) technology and a higher 200m water resistance.
A bidirectional rotating inner bezel scale used for flight calculations (fuel consumption, time, distance, and unit conversions).
Features a shimmering silver-white dial with black sub-dials (chronograph totalizers and 24-hour indicator) and sharp red accents on the hands.
Measures up to 60 minutes in 1/5-second increments.
Integrated-style stainless steel triple-link bracelet with a fold-over clasp and hidden double push-button release.
Luminous sword-style hands and baton indices for visibility in low-light environments.
