DEAR CUSTOMER,
We know from numerous
conversations that the people
who buy our watches do so out of
conviction. This includes people with
a pronounced affinity to technology
who are fascinated, for example,
by the solutions we have devised
for protection from magnetic fields
and scratch resistance. Some of our
customers, such as divers, pilots and
the German GSG 9 special police
unit, rely on their watches in their
respective careers because their lives
depends on it.
They all swear by the high
performance, resilience and
durability, as well as the quality
and precision of these timepieces.

data are reviewed and authenticated at regular intervals, as is the case
with our diving watches, for instance. We, for our part, give absolute priority
to functionality, which ultimately determines the design. Our watches only
feature technological attributes that really make sense. All the while, we
remain committed to our guiding principle that products have to speak for
themselves.
The basic question that we ask ourselves is: which innovative technologies
and materials can be employed for our craft and provide solutions for
rendering our watches even more practical for everyday use? It is often worth
indulging in a little lateral thinking to see what is going on in other industrial
sectors or fields of science. We repeatedly go to the limits of physical
resources to upgrade our watches – with the aim of making what's good
even better. Most of our best developments are yet to come!
I am delighted that you have decided to buy a SINN timepiece and hope
that it will continue to give you pleasure for many years to come.
Yours sincerely,
Lothar Schmidt

SINN SPEZIALUHREN ZU FRANKFURT AM MAIN
It was back in 1961 that pilot and blind-flying instructor Helmut Sinn founded
the company. Since then, we have been committed to producing high-
specification mechanical watches. In 1994, the graduate engineer Lothar
Schmidt took over the company. This marked the beginning of a new era
for the SINN brand, because the new owner took a decisive step towards
more innovation. Under his leadership, new technologies and materials were
introduced, thus providing the crucial incentives for our company's evolution
and gradual emergence as an insider's tip for lovers of fine watches. Today,
our name stands for technical innovations – much to the delight of both the
trade and our customers alike.

All developments thoroughly tested
Take, for instance, the absolutely condensation-
free and anti-reflective diving watch made of
stainless steel – designed with HYDRO Technology.
Other examples include a chronometer
chronograph fashioned from a 22-carat gold
alloy, which is as hard as stainless steel, and a
chronometer whose resistance to magnetic
interference is 20 times greater than normal. Or
those watches filled with protective gas and
featuring an integrated dehumidifying capsule to
counteract moisture ingress and the ageing of
the watch movement. This list would not be
complete without mentioning the development of
Einsatzzeitmesser (EZM), our 'service watches', for
special police units and border guards, and the
Temperature Resistance Technology that allows
mechanical watches to perform at temperatures
ranging from – 45 °C to + 80 °C. The 303 KRISTALL
model passed the fire and ice test during the 1998
Yukon Quest dog sledge race that crosses the icy
wilderness of Canada and Alaska, where
temperatures are known to plunge to – 40 °C. The
watch was strapped to the arms of some of the
participants on top of their protective clothing.
This was followed in 1999 by the 203 ARKTIS model.
This diving chronograph passed its field test in the
Arctic Ocean with flying colours.

Innovations and certifications
One of our most important inventions is the oil-free DIAPAL Technology, based
on low-friction materials for the key functional parts of the watch, enabling
them to run without lubrication. This technology was first employed in our
jubilee watch, the Frankfurt Financial District Watch in white gold. TEGIMENT
Technology, with which SINN achieves a virtually scratch-resistant surface for
its watches, represents another milestone. Other innovations include diving
watches made from original submarine steel, as used in the construction
of the outer shell of German Class 212 submarines. Germanischer Lloyd,
the world's biggest classification society providing marine safety services,
has been testing water and pressure resistance since 2005. Moreover, as
part of an official authentication process conducted by Germanischer
Lloyd in 2006, SINN diving watches were examined as diving gear – a first
in the watchmaking sector – and tested according to European diving
equipment standards. The result: these timepieces passed the temperature
resistance and functionality tests with a sensational success. All test results are
authenticated with a signature and seal.

Ongoing advancement in technology and quality
Our top priority has always been to develop watches that offer superior
performance – both in daily and in professional use. Which is why our
engineers are working continually to identify which innovative methods,
materials and technologies are best suited for optimising our watches.
Each new development has to first undergo rigorous practical tests before
being incorporated. And no watch leaves our workshops before it has
been subjected to thorough checking and fine adjustment by our master
watchmakers.
Workshop modifications and hand-engraving
From the robust case and the polished crystal
through to elaborate refinements: we make sure
that each and every detail of our watches is fit
for purpose. The same applies to our workshop
modifications. Only the perfect interaction of all
components and technologies ensures that our
watches can meet all their design specifications
in full. Take for example the SZ02 calibre of our
U1000 diving chronograph. The 60-minute scale
of the stopwatch minute counter is much simpler
and more intuitive to read than the 30-minute
scale commonly found on other watches. The
hand-engraving represents a highly personal
form of refinement. If required, our specially
trained master engraver can etch a name,
initials, monograms or symbols onto the rotor,
movement bridge and case back.
