data are reviewed and authenticated at regular intervals, as is the case
with our diving watches, for instance. We, for our part, give absolute priority
to functionality, which ultimately determines the design. Our watches only
feature technological attributes that really make sense. All the while, we
remain committed to our guiding principle 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
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 magnetic field protection and
scratch-resistance. Some of our
customers, such as divers, pilots or
the German GSG 9 special police
unit, need to rely on their watch in
their respective careers because
their life depends on it.
They all swear by the high
performance, resilience and
durability, as well as the quality
and precision of these timepieces.

SINN SPEZIALUHREN ZU FRANKFURT AM MAIN
It was back in 1961 that the 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 control. 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 insiders' 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.
All developments thoroughly tested
Take, for instance, the absolutely condensation-
free and anti-reflective diving watch made of
stainless steel – designed with HYDRO Technology.
Other examples include a chronometer
chronograph fashioned from a 22-carat gold
alloy, which is as hard as stainless steel, and a
chronometer whose resistance to magnetic
interference is 20 times greater than normal. Or
those watches filled with protective gas and
featuring an integrated dehumidifying capsule to
counteract moisture infiltration and the ageing of
the watch movement. This list would not be
complete without mentioning the development of
so-called Einsatzzeitmesser (EZM) watches for
special police units and border guards, and the
Temperature Resistance Technology that allows
mechanical watches to perform at temperatures
ranging from – 45 °C to + 80 °C. The 303 KRISTALL
model passed the fire and ice test during the 1998
Yukon Quest sledge dog race that crosses the icy
wilderness of Canada and Alaska, where
temperatures are known to plunge to – 40 °C. The
watch was strapped to the arm of some of the
participants on top of their protective clothing.
This was followed in 1999 by the 203 ARKTIS model.
This diving chronograph passed its field test in the
North Polar Sea with flying colours.

Innovations and authentications
One of our most important inventions is the oil-free DIAPAL Technology,
based on low-friction materials for the key functional parts of the watch,
enabling them to run without lubrication. This technology was first employed
in our jubilee watch, the palladium alloy/white gold Frankfurt Financial
District Watch. TEGIMENT Technology, with which SINN achieves a virtually
scratch resistance surface for its watches, represents another milestone.
Other innovations include diving watches made from original submarine
steel, as used in the construction of the outer shell of German class 212
submarines. Germanischer Lloyd, the world's biggest classification society
providing marine safety services, has been testing the aspects of water and
pressure resistance since 2005. Moreover, an official authentication process
conducted by Germanischer Lloyd in 2006, SINN diving watches as diving
gear for the very first time in the watch making sector and tested them
in keeping with European diving equipment standards. The result: these
timepieces passed the temperature resistance and functionality tests with a
sensational success. All test results are authenticated with signature and seal.
Ongoing advancement in technology and quality
Our top priority is always to develop watches which 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 first has to 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 in 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 meets all its design specifications
in full. For example: the SZ02 calibre of our U1000
diving chronograph. The 60 minute scale of
the stop-minute counter is much simpler and
more intuitive to read than the 30 minute scale
commonly found in 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.

But the EZM 10 is especially suitable for professional use not only on
account of its clear readability but also because of the technologies
incorporated. These include DIAPAL for a lubrication-free escapement,
Ar-Dehumidifying Technology for maximum functional reliability and
superior freedom from fogging, and Temperature Resistance Technology
which ensures accurate timekeeping within a temperature range of
– 45 to + 80°C.
The large push-pieces with Black Hard Coating on a TEGIMENT Technology
basis are integrated in the case and help ensure that the chronograph is
easy to handle even when wearing gloves. The push-pieces themselves
are not screwed in and are effectively sealed by means of the D3 system
which we developed ourselves.
The EZM 10 looks highly impressive yet is comfortable to wear — not least
due to the bead-blasted case made from high-strength titanium with
TEGIMENT Technology, used here for the first time in a SINN watch. For the
crystal we have used high-quality sapphire crystal with anti-reflective
coating on both sides.
The result is a distinct, high-performance pilot's watch which is eminently
suitable for practical, everyday use and is resistant to high and low
pressures of up to 20 bar. We provide a five year warranty on this model
on account of its superior technological features (as we do on all models
featuring DIAPAL Technology).
The EZM 10 is the result of a development idea which first came about in
2003. Our declared aim throughout the development process has been to
optimise both the movement and the features of the watch. The overriding
purpose of the redesign was to create a mission timer which meets the
demands of a professional pilot's watch to perfection.
Clear readability is of vital importance when pilots use a mechanical
watch. And so the SINN SZ01 movement has been incorporated in this
chronograph, which makes it much easier to read off stop times. Because
the SZ01 is specially designed with a centre-mounted 60 minute stopwatch
hand. This technical design feature has two advantages: firstly, 60 minutes
are now counted in one sweep of the counter instead of the usual 30
minutes, and secondly, the minute stop scale covers the entire diameter of
the dial, making it possible to read times off at a single glance. The
chronograph function indicators have been coated with orange-coloured
daylight luminous paint. This allows both the stopped times and the
current time to be read in the ultraviolet light often used in darkened
cockpits. This function is complemented by a backwards-counting pilot's
bezel with minute ratcheting and luminous key mark. As in all of our pilot's
watches, this bezel has a captive design to protect it against loss, plus an
exclusive special feature: the ring insert is made of high-quality sapphire
crystal glass.

The SZ01 chronograph is based on the successful Valjoux 7750 and has been
specially developed by SINN. The development work began back in 2003.
The main priority in undertaking the redesign was to make the chronograph
functions significantly easier to read off. Which is why we attached so
much importance to finding a first-class technical solution to mounting the
stopwatch minute hand in the centre of the dial. This allows users to take
accurate stop times even more quickly and simply. The clarity and distinct
readability of this chronograph stem from the design of the well-known
Lemania 5100 movement.
Our redesign enhances the readability in two ways: firstly, 60 minutes are
now counted in one sweep of the hand instead of the usual 30 minutes, and
secondly, the minute stop scale covers the entire diameter of the dial.

INSTRUCTIONS FOR USE
To wind 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 its reliable
functioning. 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 rewind it.
Time adjustment (crown position 3)
In crown position 3, the motion is paused. This helps you to set the watch
precisely. For accurate time setting, we recommend moving the hand past
the desired minute marker and then adjusting it counter-clockwise. Please
make sure that the date changes at midnight and not at midday when
adjusting the time. Move the hand forward until the date changes before you
attempt to set the time. The movement restarts as soon as you leave crown
position 3.
Quickset date adjustment (crown position 2)
Do not use this function between 9 p.m. and 3 a.m. Set the crown in the
position 2 and turn it clockwise until the correct date appears in the date
display window. Please do not use the date setting function between 9 p.m.
and 3 a.m. Between these times, the gear wheels used for changing the date
are engaged, and the movement could become damaged.
Please take care to fasten the crown after making adjustments.

Using the pilot's bezel to measure time
The pilot's bezel is an outer ring divided into minutes, and 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.
The triangle can be set in relation to the hour hand, minute hand or centre
second hand.
Using the chronograph to measure time
The chronograph is operated by means of buttons "A" and "B". The
measurement starts when button "A" is pressed once. Pressing this button
again stops the measurement. The measurement is resumed by pressing
button "A" once more. This allows you to add up and record the cumulative
time. Button "B" resets the hands of the chronograph to zero.
