Haller rotary pendulum movement for screw pointers

Resistant, patented quartz rotating pendulum movement without a pendulum spring
Secure, fixed bearing, for pendulums with rigid axles (no pendulum springs)

• No vulnerable spiral or pendulum spring
• Secure fixed storage, no use of adjusting washers
• Extremely quiet, slow running
• Does not require exact alignment of the clock in the "water" (the previous exactly horizontal base/alignment, which one had to pay attention to in the past with mechanical annual clocks, is no longer necessary - the innovative, quartz-controlled annual clocks also run on a slightly "sloping" surface, which just isn't is exactly "in the water")
• Robust - over-tightening is not possible.
• Running time up to two years with an alkaline mignon cell, type "AA"
