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 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

Aviation, in all its forms, combines emotion and
technical excellence like almost no other mode of
transport. It’s not just pilots who have always
demonstrated their connection to flying by wearing
a special timepiece – the pilot’s watch.
In the early days of aviation, the pilot’s watch was
one of the primary navigation instruments
alongside the aviation map and a compass.
Charles Lindberg would rather have gone without a
radio than a second timepiece on his legendary
transatlantic flight. To this day, most flight
procedures in instrument flying carry a
corresponding time stamp.
“Pilot’s watch” is however not a protected term. It is
often used for purely design-oriented models, which
hardly do justice to the technical requirements for a
flight instrument. It was therefore natural for the
Department of Aeronautics and Astronautics at the
Aachen University of Applied Sciences, as one of
the leading educational and research facilities for
aviation, to take on the development of a test
standard based on the official certification
procedure for general aviation. A considerable

number of pilots, airline companies and engineers were involved in creating
the requirements and the development of the extensive test procedures.
TESTAF, the technical standard for the pilot’s watch, was officially presented to
the public in the autumn of 2012, in the deliveries hangar of the Airbus Helicopter
company (formerly Eurocopter) in Donauwörth. The advisory board set up for
this purpose, consisting of recognised experts in aviation and the watch industry,
will ensure the future continuous updating and technical advancement of the
contents and test procedures.
The team at Sinn Spezialuhren, led by Lothar Schmidt, of course immediately
took on this challenge and met all requirements with flying colours after an
intensive development phase. You hold the result in your hands today, the
TESTAF-certified pilot’s watch – a very special timepiece.
Sincerely
Prof. Dr.-Ing. Frank Janser

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.
