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
depend on it.
They all swear by the performance,
resilience and durability, as well
as the quality and precision of our
watches. That is why the world’s
largest classification society DNV GL
(formerly Germanischer Lloyd,
Hamburg) regularly tests and certifies
the water and pressure resistance of
our diving watches.

We have selected pilot’s watches tested and certified to the technical
standard for pilot’s watches (TESTAF) by Aachen University of Applied
Sciences. The TESTAF ensures that a pilot’s watch meets all timekeeping
requirements during flight operations in accordance with visual and/or
instrumental flight regulations and is suitable for professional use. Functionality
is our top priority and ultimately determines the design. Only the technical
features that are really needed can be found on our watches. Because we
believe 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.

Advancements in endurance testing
Take, for example, the absolutely condensation-
free, anti-reflective, german submarine steel diving
watch – made possible by HYDRO Technology.
Other examples include a chronometer
chronograph fashioned from a 22-carat gold alloy
that is as hard as stainless steel and a chronometer
with a magnetic resistance of up to 80,000 A/m.
There are also watches with a clockwork
mechanism optimally protected from aging
by an inert gas and integrated dehumidifying
capsule. The list would not be complete without
mentioning the development of mission timers
(Einsatzzeitmesser or EZM in German) for firefighters,
for special police units and border patrol guards
as well as Temperature Resistance Technology
to keep mechanical watches performing at
temperatures ranging from − 45 °C to + 80 °C. This
technology has proven its worth in the EZM 10
TESTAF model, for example, used as part of the
official approvals procedure for Airbus Helicopter’s
(formerly Eurocopter) EC 145 T2 high-performance
helicopter. Hot and cold climate tests and high-
altitude experiments were carried out in the
deserts of the USA, the Rocky Mountains and the
frozen wastes of Canada. The watch was worn
unprotected, outside the pilot’s overall, during cold
climate tests at temperatures reaching − 45 °C.

Innovations and certifications
The world’s largest classification society for maritime safety DNV GL (formerly
Germanischer Lloyd, Hamburg), has been testing our diving watches
for pressure and water resistance since 2005. As part of DNV GL’s official
certification process, our diving watches have been treated as part of diving
equipment since 2006 and tested and certified in accordance with European
diving equipment standards. This is unparalleled in the watch industry.
We have had selected pilot’s watches tested and certified to the technical
standard for pilot’s watches (TESTAF) by Aachen University of Applied
Sciences since 2012. The TESTAF, the result of a research project at the initiative
of Sinn Spezialuhren, ensures that a pilot’s watch meets all timekeeping
requirements during flight operations in accordance with visual and/or
instrumental flight regulations and is suitable for professional use.
DIAPAL is one of our most important technological developments, with oiling
no longer needed for the most important functions in the watch thanks to
the materials we select. This technology was first used in 2001. With the aid
of TEGIMENT Technology, we achieve greatly increased scratch resistance
through surface hardening.

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
engraver can etch a name, initials, monograms
or symbols onto the rotor, movement bridge and
case back.

DNV GL CERTIFIES SINN DIVING WATCHES
So what does DNV GL (formerly Germanischer Lloyd) have to do with a
watch manufacturer from Frankfurt am Main? The renowned company tests
and certifies our diving watches according to a variety of criteria. One
test focuses on water resistance and pressure resistance, while a second
test procedure covers something never done before in the watchmaking
industry: certification in accordance with the European standards for diving
equipment!
Testing for water resistance and pressure resistance
In each dive, time plays a crucial role in survival on every dive. Diving
watches must therefore be water-resistant, reliable and durable, and
guarantee perfect readability in all lighting and water conditions. The
information we provide about our diving watches is thus not merely captured
in words, but proven in practice as well. Since 2005, DNV GL has been
testing our diving watches for water resistance and pressure resistance. In
accordance with these certification standards, the EZM 3 and EZM 13 are
pressure-resistant to 50 bar, the T1, U1 and the U1000 series are pressure-
resistant to 100 bar, while the T2, U2 and U200 series are pressure-resistant
to 200 bar and the UX series is actually pressure-resistant to any accessible
diving depth. For this series, DNV GL has confirmed the pressure resistance
of the case to 12,000 m and of the movement to 5,000 m diving depth. The
tests are repeated at regular intervals on all of these watches in order to
document the consistency of the quality.
