German Mechanical Skeleton Clock with Numerals on Glass

A skeleton movement standing under a tall conical glass dome, its brass wheels and escapement fully exposed and the numerals printed onto the glass itself rather than a dial. The base is polished mahogany. Made in Germany by Hermle, whose movements have been built in the Black Forest region since 1922.

Care Instructions

• Wind the movement at the interval stated for the model, always at the same time of day.
• Move the hands forward only, pausing at every chime or strike until it completes.
• Dust the case with a soft, dry cloth; use a wood-appropriate polish on wooden cases only.
• Clean the glass with a cloth lightly dampened with glass cleaner — never spray directly onto the clock.
• Keep away from radiators, direct sunlight, and humidity, and have the movement serviced by a specialist every few years.

Frequently Asked Questions

What does "skeleton" mean?
A design that leaves the movement exposed rather than hidden behind a case, so you see the wheels, the mainspring and the pendulum at work. It is not decoration applied to the mechanism — the mechanism itself is the display.

Why are the numerals printed on the glass?
Because a conventional dial would hide part of the movement behind it. Printing the numerals directly onto the glass keeps the wheels and escapement visible from front and back — the clock is read without concealing anything. A precise technical detail that sets this model apart.

How does a mechanical clock work?
With no electricity and no battery — a metal mainspring that you tension by hand when winding. The spring stores that energy and releases it slowly and precisely through a train of wheels, while the pendulum swinging in front of you regulates that release and keeps it even. As each hour passes, the movement frees a single bell strike to mark it.

This is the same principle clocks have run on for centuries, and it is what allows a single winding to last 14 days. Thanks to the skeleton construction, you watch the whole process happen: the spring, the wheels, and the pendulum measuring time.

How often does it need winding?
Every 14 days — a two-week power reserve on a single winding.

How does it differ from the other Leyton finishes?
The Leyton comes in four finishes sharing the same movement, the same numerals-on-glass construction and the same 35 cm format. The difference is the wood and its character: mahogany offers a warm, even, classic tone that stays as it is; walnut burl carries a unique natural figure that never repeats; cherrywood deepens in colour over the years into a rich red-brown; and piano black gives the highest contrast against the nickel-plated wheels.

How large is it, and is it covered by warranty?
35 cm high and 18 cm in diameter, with a two-year manufacturer's warranty in original Hermle packaging.

About Hermle

Franz Hermle & Sohn was founded in 1922 in Gosheim, in Germany's clockmaking heartland near the Black Forest. Within a decade it had become one of the most advanced makers of clock movements in Europe, and it remains among the world's largest manufacturers of mechanical movements. Now in its third generation, Hermle builds every movement in Germany and supplies clockmakers across the globe.
