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.

With their sheer elegance and design, the 1736 Classic and 1746 Classic –
which are distinctive on account of their different diameters – are the
embodiment of true style. One of the most striking hallmarks is the clear
focus on the hour, minute and date display. The elements are arranged in
such a way as not to distract from the classic design of the case. The striking
visual impression is underscored by a pure white, particularly exquisite
lacquered enamel dial.
The words “Sinn Frankfurt am Main” serve both as an indication of the watch's
provenance and a seal of quality. The discreet lettering allows plenty of room
for the Roman numerals on the edge of the dial, making the watch eminently
easy to read.
The timepieces combine classic elegance with technical precision. The case
is made of polished stainless steel. The anti-reflective, sapphire crystal base
allows an unobstructed view of the impressive movement with blued screws.

Winding the watch (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 counter-clockwise until the correct date
appears in the date display window.

MODEL 1746 PORCELAIN
Founded in 1746, the white gold of Hesse of the Höchst Porzellanmanufaktur
in the western part of Frankfurt is one of the finest examples of artistic
European craftsmanship.
These mechanical precision watches with hand-painted dials made of
the finest Höchst porcelain of this watch model were created through
collaborative development. Art and watch lovers can choose from traditional
and contemporary motifs in various colors. The watch is particularly suitable
for stylish customization. Upon request, the porcelain dial can be additionally
decorated with monograms or family coats of arms for the maximum
expression of individuality and personality.

General advice
To preserve the water resistance for as long as possible, the watch should
be rinsed whenever it has been in contact with seawater, chemicals, etc.
If your watch is frequently worn in water or underwater, we recommend
having its water resistance checked at yearly intervals.
The watch is designed to withstand high levels of mechanical wear and
tear and is shock resistant as per DIN 8308. Nevertheless, it goes without
saying that continual mechanical stress in the form of impacts or vibration
will affect its durability.
Care should therefore be taken to protect your watch from unnecessary
wear and tear. It is only possible to judge how well the watch keeps time
after it has been in operation for approximately eight weeks, since it takes
that long for the working mechanism to become adjusted, especially in
view of the fact that everybody has different lifestyles and habits. In the
event of any excessive deviation, please keep a day-to-day record of its
timekeeping over a period of about one week, for example.
