Setup, Compatibility & Care
Setting up your Hermle regulator clock requires careful handling to ensure the pendulum is hooked correctly onto the leader. Once mounted, use a spirit level to ensure the clock is perfectly vertical; an unlevel clock will cause the pendulum to stop swinging. Keep the clock away from heating vents, direct sunlight, or extreme humidity, as these can affect the wood case and the metal movement's precision. For maintenance, periodically dust the decorative glass and wood casing with a soft, dry cloth. Do not use chemical cleaners on the finish. If the clock loses or gains time, move the adjustment nut at the bottom of the pendulum bob: turn it up to make the clock run faster or down to make it run slower.
