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.

11
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.

THE WORLD’S FIRST,
TESTAF-CERTIFIED TIMEPIECE
In a research project lasting four years, the Faculty of Aerospace Technology
of the Aachen University of Applied Sciences (FH) and Sinn Spezialuhren
have developed a technical standard for pilots’ watches (TESTAF). TESTAF
ensures that a pilot’s watch meets all of the time measurement requirements
for flights operated under visual flight rules (VFR) and/or instrumental flight
rules (IFR). The EZM 10 TESTAF, the 103 Ti TESTAF, 103 Ti UTC TESTAF and the
857 UTC TESTAF were the first SINN watches to undergo and pass the strict
test procedures.
For these watches to meet all the test criteria, we had to make various
adjustments to them. The watches then passed all of the tests with flying
colours. This means that they are suitable for professional use as a pilot’s
watch – a fact that is documented by a certificate and the TESTAF seal of
quality on the face of the watch.
What are the distinguishing features of a professional pilot’s watch? To
provide a universally valid answer to this question, it was necessary to
formulate a norm or standard, which did not exist for pilots’ watches until
today. And so in 2008, engineer Lothar Schmidt, managing director and
owner of Sinn Spezialuhren, took the initiative to close this research gap
together with engineering professor Frank Janser of the Aachen University of
Applied Sciences.

13
TESTAF now provides the answers. For example, a pilot’s watch must withstand
rapid temperature changes and changes in ambient pressure up to
0.044 bar – equivalent to an altitude of about 21,300 metres.
A pilot’s watch is thus subjected to several thousand pressure change cycles
in order to simulate the actual stress conditions on a pilot’s wrist. Besides
being water-resistant, the watch must also be resistant to common aviation
fluids such as fuels, hydraulic fluids and cleaning and de-icing agents. It is
also important that the magnetic field of the pilot’s watch itself does not
interfere with the avionics such as the aircraft’s emergency compass. It may
not dazzle the pilot or produce unnecessary reflections. The watch must also
be resistant to shocks and vibrations and be perfectly readable in the dark.

14
The list of technical and functional specifications describe precisely and
unambiguously the time measurement requirements during flight in the
following categories.
1. Functionality
• Required functions during flights operating under visual and/or
instrument flight rules
• Readability in daylight and in darkness
• Good operability
• Accuracy and power reserve
2. Resistance to external stress
• Absolute and cyclical ambient pressure changes
• Operative temperature range and rapid temperature change
• Shock and impact resistance, G-forces and vibration
• Resistance to water and other aviation fluids
• Effects of magnetic fields on the watch
3. Safety and compatibility with other instruments
• Effects of the watch’s magnetic signature on avionics
• Avoidance of reflections and dazzle
• Appropriate form
• Secure strap fastening
A description and photos of the tests can be found at www.testaf.org.

Designed as instruments for professional use, our pilot watches must satisfy
extremely high requirements when it comes to reliability and performance. In
order to satisfy these requirements, this mission timer was tested and certified
by Aachen University of Applied Sciences in accordance with the technical
standard for pilot watches (Technischer Standard Fliegeruhren – TESTAF).
This ensures that the EZM 9 TESTAF is qualified for professional use as a pilot
watch to the highest level and is evidenced with a certificate and the TESTAF
quality seal on the dial.
Other features increasing the application quality of this timepiece include
the case, which is made of high-strength titanium. This particularly lightweight,
extremely high-strength material offers great wearer comfort due to its non-
allergenic properties. The surface of the case has also been hardened
using TEGIMENT Technology, making it especially scratch-resistant. Additional
Ar-Dehumidifying Technology guarantees enhanced functional reliability and
freedom from fogging, while Temperature Resistance Technology ensures
functional reliability from − 45 °C up to + 80 °C. Another special feature is the
pilot’s bezel. This has a captive connection to the case and boasts a bezel
insert made of high-quality sapphire crystal glass.

Winding the watch (crown position 1)
The crown is screwable (crown position 0). To loosen the crown, turn it counter-
clockwise (crown position 1). The movement is wound by turning the crown
clockwise. About 40 winds of the crown are generally enough to ensure
reliable functionality. Under normal circumstances, simply wearing the watch
every day should suffice to keep the self-winding mechanism wound. The
power reserve allows you to take off your watch overnight without having to
re-wind it.
Time adjustment (crown position 3)
In crown position 3, the motion is paused. This helps you to set the watch
precisely. Please make sure the date changes at midnight and not at
midday. Just move the hands forward until the date changes. Afterwards you
attempt to set the time. We recommend moving the hands past the desired
minute marker and then adjusting it backwards. The movement restarts as
soon as the crown is no longer in position 3.
Quickset date adjustment (crown position 2)
Set the crown in position 2 and turn it clockwise until the correct date
appears in the date display window.
Please take care to fasten the crown after making adjustments.

Using the pilot’s bezel to measure time
The pilot’s bezel can be moved manually in both directions. The triangle
glows in the dark. It can be used in a number of ways, including to measure
important lengths of time. For example, you can set the marking to the
beginning of the time span to be measured, or you can use it to indicate the
end of a given span of time.
