perpetual calendar. Heinrich Sattler designed exactly the clock that he would like to buy, but never found. His
classical clock making, perfect craftsmanship and innovation were his aim. So in 1958 he founded his own
company: Erwin Sattler München. In the middle of the 80`s his daughter Stephanie Sattler-Rick took over
financial control and the clockmaker Richard Müller joined the management as technical leader. Together,
they progressively transformed the company into a manufacturer. In 2002 Erwin Sattler retired and handed
company in the ideals of its founder: clocks for generations to come. Erwin Sattler's dream came true. Today,
the precision clocks of the Erwin Sattler factory, produced in small batches, are reckoned as the best in the
world. Professionals as well as collectors regard them as the standard for technical innovation, elegance and
highest quality. For almost 50 years we have only made clocks, that we would buy for ourselves, clocks, so
high class they can be passed from generation to generation.
The Development
What Erwin Sattler and clock enthusiasts regard as precision depends on many factors. The more precise a
mechanical clock has to be, the more important the details. Precisely cut teeth, the choice of the right material
and reliable compensation for atmospheric influences increase the accuracy by only fractions of a second, but
this is exactly what makes the difference between a clock and a precision pendulum clock. This is why the
Erwin Sattler factory has its own research and development department. The only goal is to develop and
optimize mechanical precision timekeepers. Here we use high-tech instruments to check historic theories and
developments for their day to day practicality. The theoretical knowledge gained is put into prototypes. With
computer aided calculation of gears, the use of gears with a high number of teeth and fitting the movements
with jewels and ball-bearings we optimized the transmission of power. In this way we save up to 50 % of the
normal driving weight, at the same time the longevity of the movement is extended significantly. To ensure
quality we operate a unique laboratory that enables our designers to simulate environmental influences on a
pendulum. In our pressure chamber, we check the effect of pendulums of different weights when air pressure
changes, to determine the exact degree of compensation, which has previously been calculated
mathematically. Therefore our clocks keep accurate time up to 1 sec/month. Using unusual materials we find
new answers on old questions. Driving weights made of tungsten, invar pendulum rods, extremely low friction
ball bearings and air pressure compensation aneroid are only some examples. Richard Müller, co-owner and
technical leader of the Manufacture Erwin Sattler invests continuously in the research and development
department to increase the technical progress. This gives our creative designers the opportunities they need
for their ideas and visions.
The Manufacturing
With regard to our customers, we have only one goal: total satisfaction. This includes the design, quality and
durability of our products. The long development process from the first sketch to the finished product is a
well-balanced relationship between modern technology and traditional craftsmanship. Only this guarantees
that every detail of a Sattler clock fully achieves our high expectations. The 25 employees at the Erwin Sattler
factory daily live the dream: clocks for generations. For the production of our movement parts we use
high-tech CNC machines, without them tolerances up to max. 1/100 mm would not be possible. But the most
important factor when making high-quality precision pendulum clocks remains the human factor in finishing and
assembling these examples of mechanical art. Guided by Richard Müller, the master clockmakers and
clockmakers working in production, development and assembly, build the most accurate precision pendulum
clocks in the world. All our movement parts are turned or milled from the solid metal. Following to the plans of
the development department, highly precise parts are produced from hardened brass and steel are produced.
Each of our 13 movements, produced in small batches, originates in our own development department. Our
high quality cases are manufactured in Germany to our demanding specifications, by a company specializing
in wood technology. We make manufacture about 90 % of each clock and can therefore be called a
manufacturer. Men and clocks have one thing in common. They need a future. This is why we train young
people to become clockmakers. Currently we have 4 clockmaker apprentices. Jan Münch, a Sattler apprentice,
won the German watch and clock making competition in 2004, showing that this effort has positive results.
The Movement Quality
The Production of the up to 420 parts of our complex movements takes time. Engraving the scales for a the
hour, minute and second hands. Each hand is filed in the traditional way to produce a half round shape, the
clockmaker calls it "profiling". Afterwards the hands are sanded, polished, and heated with a gas flame until
they have an even shiny blue color. Our plates, between which all moving parts are mounted, are made from
hardened brass. They are up to 5 mm thick and extremely solid. Each bearing hole is individually positioned
and drilled in our CNC controlled machine. This takes longer than simultaneous drilling in multi-spindle
machines, but it is much more precise. The elegantly shaped wheels canters are not punched out, but are
milled. They are mounted on solid, hardened, arbors with precisely milled teeth. For lasting protection against
oxidation all brass parts are gold-plated. The use of agate pallets, jeweled bearings and modern ball bearings
optimizes performance and avoids material wear. The clocks require relatively small driving weights and run a
long time without servicing. The use of high-grade materials and our computerized machines, but most
importantly the high standard that each employee expresses in his work, result in the unique Sattler quality.

Completion of a new Sattler movement, before it can be fitted in its case, can take up to 2 years. A long time,
but actually nothing, compared with the centuries a Sattler clock will last: clocks for generations.
The Case Quality
If you purchase a Sattler clock you should have one thing in mind. This timepiece will have other owners,
because it will survive for generations. All the parts, the hidden and visible get the same care. For the
production of our unique, elegant cases, the same guidelines apply as for our movements. We use only the
best materials, combined with modern production methods and the traditional skills of the carpenter.
Appearance, legibility, protection of the movement, stability and longevity, are musts for a Sattler case. The
natural wood used for our cases must be dried for many years so that it does not warp. The slender fillets of
the front doors in particular must be made thinner and thinner in several steps. Between each step, they must
be stored for months. When all the parts have the correct dimensions, they are varnished. Between applying
each of the 13 layers of varnish, the surface must be sanded by hand every time. This is why the varnishing of
a Sattler case takes 14 days. As a result the surface is very smooth with a silky shine which, like everything on
our clocks is extremely durable. Large, beveled and polished glazing guarantees the desired visibility. The
dimensions of the facets and all proportions of a case are perfectly composed and are often inspired by
antique clocks. This is the most important function of a Sattler case: timeless beauty. Precious long stored
wood, beveled glass, high quality multi layered varnish and, most important, attention to detail, achieve the
quality that you can expect from precision clocks from Erwin Sattler. Clocks for generations.
