This is a Schatz watch from Germany, produced around the 1950s or 60s. It has a mechanical movement; the minute hand adjusts the time. Its mechanism works by the left-right oscillation of a wheel, which is currently in good condition during transport. It's well-protected and will be securely held in place. It's 15cm tall, 8cm in diameter, with a base diameter of 10.2cm, and weighs 463g. Dear collector, do you have this one? Thank you for your appreciation.
