This beautiful model of Schatz 400 day clock was made from the mid-1950s into the 1960s or early 1970s. Here is one that I just finished repairing. The case is in good original condition. The movement needed cleaning, one pivot polished, and a new suspension spring.
Below is a photo of the gears and anchor before the back plate and anchor bridge were put on, followed by photos of the complete clock, the back, and a closeup of the back showing the locking device engaged with the pendulum (there is also a locking lever on the front, which is moved to the left to lock the pendulum).
Below are videos of the escapement in action, and the complete clock running with and without the dome.
Back plate: 1013A
Suspension unit: 10A
Suspension spring: 0.0024 inches (most of these clocks need a .0023 inch thick spring, but this one needed a .0024 to rate properly
Movement date: 8-55 (August 1955)
