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 Hamburg-based
Germanischer Lloyd 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
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

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 20 times the standard.
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 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 Eurocopter's 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
Germanischer Lloyd, the world's largest classification society for maritime
safety, has been testing our diving watches for pressure and water resistance
since 2005. As part of Germanischer Lloyd'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
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 master engraver can etch a name,
initials, monograms or symbols onto the rotor,
movement bridge and case back.

Just how functional can a watch be? This is a question we've been asking
ourselves since founding the company. And the answer? Our cockpit
navigation clocks. Conceived for the instrument panels of aeroplanes and
helicopters, and optimised to provide rapid and clear readability, they are
specifically designed to offer time measurement in its purest form.
And they have now inspired us to create a watch with these same
characteristics as well as Magnetic Field Protection of up to 80,000 A/m to
complement our range of instrumental chronographs.
The dial design ensures especially clear readability: Maximum contrast of the
hands, indices and numerals against the glare-free black dial. – Extremely
large numerals for intuitive orientation even in low light levels. – Striking hand
profiles. – Special long-lasting, luminous paint on the minute and hour hands
and indices to ensure accurate reading even in adverse conditions.

The technical specifications of the 856 UTC provide impressive proof of our
craftsmanship in the area of instrument watches. The second time zone on
a 24-hour basis makes it ideal for people who frequently find themselves
crossing time zones because of travel.
The aesthetics of this watch are determined by the striking form - a form
which, as in all our watches, is dictated exclusively by the functions. The
856 UTC also features a range of technologies which, together, guarantee
maximum reliability even in the most extreme of conditions.
In addition, the 856 UTC has a second time zone on a 24-hour basis with a
hand which helps to locate the points of the compass. The hand is designed
in the form of an arrow for this very purpose. The basic principle is simple: in
the northern hemisphere, you hold the watch horizontally and turn it so that
the 12-hour hand is pointing towards the sun - the 24-hour hand will then be
pointing North. In the southern hemisphere, on the other hand, the same
procedure will cause the hand to point South.

Based on the 856 series, and designed as a functional instrument watch
in the tradition of our cockpit navigation clocks, this pilot's watch also
features a pilot's bezel which permits its wearer to measure or check set time
intervals. This is a decisive criterion particularly in aviation – reason enough
for us to give this important function a superior design.
The stainless steel pilot's bezel with minute ratcheting can be rotated on
both sides and features a special mechanical system developed by SINN to
protect against loss. Like the case material, the base of the bezel is tempered
with TEGIMENT Technology. The labelling is silver on an inset, black anodised
aluminium ring to ensure optimal scale readability. A luminous triangle serves
as the 0 / 60 minute mark. The pilot's bezel can be turned in both directions
and clicks firmly and audibly into place at minute intervals.

The 857 UTC series pilot's watches unite all our core watchmaking
competencies: these are instrument watches with a consistently functional
design which honour the tradition of our navigation cockpit clocks.
The features include Magnetic Field Protection of up to 80,000 A/m,
Ar-Dehumidifying Technology and pressure resistance of up to 20 bar.
The pilot's bezel and the second time zone on a 24-hour basis make these
watches perfect, all-purpose instruments.

Winding the watch (crown position 1)
The crown is screwable (crown position 0). To loosen the crown, turn it counter-
clockwise. 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 counter-clockwise until the correct date
appears in the date display window.
Please take care to fasten the crown after making adjustments.
