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.
5
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 highspecification 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 condensationfree, 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 highaltitude 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.
9
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.

DNV GL CERTIFIES SINN DIVING WATCHES
So what does DNV GL (formerly Germanischer Lloyd) have to do with a
watch manufacturer from Frankfurt am Main? The renowned company tests
and certifies our diving watches according to a variety of criteria. One
test focuses on water resistance and pressure resistance, while a second
test procedure covers something never done before in the watchmaking
industry: certification in accordance with the European standards for diving
equipment!
Testing for water resistance and pressure resistance
In each dive, time plays a crucial role in survival on every dive. Diving
watches must therefore be water-resistant, reliable and durable, and
guarantee perfect readability in all lighting and water conditions. The
information we provide about our diving watches is thus not merely captured
in words, but proven in practice as well. Since 2005, DNV GL has been
testing our diving watches for water resistance and pressure resistance. In
accordance with these certification standards, the EZM 3 and EZM 13 are
pressure-resistant to 50 bar, the T1, U1 and the U1000 series are pressureresistant to 100 bar, while the T2, U2 and U200 series are pressure-resistant
to 200 bar and the UX series is actually pressure-resistant to any accessible
diving depth. For this series, DNV GL has confirmed the pressure resistance
of the case to 12,000 m and of the movement to 5,000 m diving depth. The
tests are repeated at regular intervals on all of these watches in order to
document the consistency of the quality.
11
Germanischer Lloyd (now
DNV GL) has confirmed
and certified the pressure
resistance.
12
A premiere: certification in accordance with European diving device
standards
In a standardised test situation, will a diving watch deliver the same reliable
performance as, say, a breathing apparatus? To answer this question, we were
the first who have watches tested and officially certified according to the
European standards for diving equipment. Also these tests are performed at
regular intervals for all these watches. The testing and certification according
to the European standards EN250 and EN14143 was completely new territory
for both sides. This was the case because the standards for diving equipment
cannot be applied to watches without modification. The experts at DNV GL
thus adapted the standards appropriately and defined two series of tests. In the
first of the two, they put the timepieces in a test cabinet for three hours at –20°C,
then for three more hours at +50°C. The timepieces were subsequently checked
for accuracy and functional reliability at both temperatures. In a second test,
the watches had to withstand three hours at –30°C and 3 hours at +70°C with
95% humidity. The result: Temperature resistance and perfect functioning were
documented and certified for the watches in the U1, U1000 (since 2007), U2,
U200 (since 2009), T1, T2 (since 2013), EZM 13 (since 2014) and EZM 3 series
after both tests. The UX series watches were also certified; however, these were
subjected to a modified test involving temperatures between –20°C and +60°C
due to their battery operation and oil filling.
13
Germanischer Lloyd (now
DNV GL) has confirmed
and certified the
type-based test of
temperature resistance
and functionality in
accordance with the
European diving device
standards EN250:2000
and EN14143:2003.

The diving watch EZM 3 is a mechanical watch made for the toughest diving
jobs. This is because you can always rely on classical mechanics anywhere
where a watch with a quartz movement could pose a risk due to electronic
interference or failure of the internal power supply. This is especially true
when these mechanics are protected by sophisticated Sinn technology.
Filling the case with a protective gas keeps ambient oxygen and other
corrosive gases at bay. The integrated drying capsule with its copper sulfate
filling also absorbs the inevitable humidity which diffuses into the watch. The
combination of carefully selected material dimensions and qualities together
with perfect workmanship and complex sealing measures – such as double
O-rings on the screwable crown – permits the approved use of the diving
watch EZM 3 for a diving depth of 500 meters, corresponding to a pressure
of 50 bar. This is an extreme performance value for which Magnetic Field
Protection is crucial: an additional, solid soft iron sheath around the movement protects the accuracy of the watch up to magnetic field influences
amounting to 80,000 A / m. All functions and printing on the dial not relevant
to diving are muted in red.

Perfect freedom from fogging
All watches in this series are water-resistant as per DIN 8310. But even with
watertight instruments, the air enclosed in the case contains water in a
gaseous state. And air can also penetrate the seals. When the water vapour
in the case condenses into liquid, the instruments are impossible to read.
To prevent this from happening, we have developed the Ar-Dehumidifying
Technology. The combination of a special drying capsule, EDR seals (extreme
diffusion reduction) and a filling of protective gas guarantee that the crystal
remains free from fogging, even in difficult conditions.
Longer service intervals
The sophisticated Ar-Dehumidifying Technology considerably slows the aging
process of the watch’s inner workings and keeps the movement functioning
properly for longer. That is why we issue a three-year warranty on all our
watches featuring Ar-Dehumidifying Technology. When the drying capsule
is saturated, as indicated by a deep blue colour (refer to picture on the left
side), we recommend you have it exchanged so you can continue to enjoy
all the advantages of the Ar-Dehumidifying Technology (enhanced reliability,
longer intervals between maintenance).

Winding the watch (crown position 1)
The crown is screwable (crown position 0). To loosen the crown, turn it counterclockwise (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.

ADJUSTING THE LENGTH OF THE WATCH STRAPS
If you don’t know how to shorten or lengthen the solid bracelet, please
contact your SINN dealer or the watchmakers in our customer service
department in Frankfurt am Main. Our customer service employees are also
happy to help you over the telephone.
Adjusting the length of the solid bracelet
Determine the relative lengths of the two sides before adjusting the length of
the bracelet. To ensure maximum comfort, both sides of the bracelet should
contain the same number of links. If this is not possible, the top bracelet strap
(above the 12 on the clock) should be longer.
It is not necessary to detach the solid bracelet from the watch or the clasp.
1. Loosen the screws on the side of the bracelet link which is to be removed
or added.
2. Remove the superfluous bracelet link or insert a new one.
3. Before screwing tight, add a small drop (no more!) of thread-locker
(AN 302-42 medium-tight) to the thread of the bracelet screw.

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.

Our international partners generally offer on-site service. However, should they
be unable to provide a certain service, they will organise the safe dispatch
and return of the SINN watch to our manufactory in Germany. Please be aware
that our partners will wait until they have a sufficient number of SINN watches
before they post a shipment, in order to keep transport costs and customs
duties to a minimum. This will increase the processing time.
Alternatively, you can send your SINN watch to us directly. You will be required
to cover the postage costs for the delivery and return shipment, which vary
depending on the country. For insurance reasons, we strongly recommend
sending us any return goods by registered parcel post. We regret that we are
