24-Hour Display Flight Wristwatch Black Square Case Manual Winding Sea-Gull 839.23.3017H

Unlike all other 12-hour watches, this watch displays 24 hours. Thus, its hour hand turns one circle per day, making it easy to tell AM and PM at a glance. Its manual movement is a piece of artwork characterized by Geneva stripes, a swan neck, a retro classic balance wheel, and hand-polished steel wheels. It has at least 55 hours of operating time.
