DEAR CUSTOMER,
Since the company was founded
in 1961, we have focused on the
creation of high-quality mechanical
watches. Nowadays, watch lovers
associate innovation and patents
with the name of Sinn Spezialuhren.
And it’s not just our diving watches
that stand for high performance,
robustness, and durability, quality
and precision.
These watches do, however,
constitute an outstanding example of
how we repeatedly push the limits of
what can be achieved physically in
development.
We are driven by the question
of which new technologies and
materials can be used to make
diving watches safer and more
suitable 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. It is therefore no coincidence
that the series U1, U2, U200, U212, U1000 and UX are made from high-strength,
seawater-resistant German submarine steel. The T1 and T2 models are
another example. All case parts for these mission timers are made from high-
strength titanium. Both submarine steel and high-strength titanium predestine
our diving watches for use in salt water.
Fittingly, we work closely with an independent company specialising in
technical maritime security. The world’s largest classification society DNV GL
(formerly Germanischer Lloyd, Hamburg) checks and certifies the diving-
watch data – including compliance with European diving device standards,
which is unique in the watch industry.
I am delighted that you have decided to buy a SINN diving watch 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
Helicopters (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 watches (Technischer Standard Fliegeruhren – 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.

PERFECT DIVING WATCHES
Our watches are famous for their outstanding functionality. We
consistently implement this principle in our accurate timepieces
for pilots as well as in our diving watches. The technical
development of such perfect time-keeping instruments is one
of the greatest challenges for our engineers and watchmakers.
During a dive, absolute water resistance, perfect readability in all
lighting and water conditions and extreme durability are of life-
saving importance.
This is due to the fact that we develop these watches exclusively
for their intended purpose – with the consequence that the form
follows the primary function. Thus we ensure an extremely high
standard of reliability, safety and practicality in everyday use.

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, U212 and the U1000 series are pressure-
resistant 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.

13
Germanischer Lloyd (now
DNV GL) has confirmed
and certified the pressure
resistance.

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, U212 (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.

15
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.

Rescuing the hijacked “Landshut” aircraft on October 18, 1977 in Mogadishu
made the German GSG 9 (Grenzschutzgruppe 9) special forces world-
famous. Just as legendary as the reputation of the anti-terrorism unit of the
German federal police is the diving watch that their maritime unit wears
during its missions.
One of the most outstanding features of these watches is the use of
HYDRO Technology. Because the watches are filled with HYDRO-oil, they
offer unsurpassable advantages during diving missions. They are completely
free from fogging and are reflection-free under water, so they can be read
from any angle. Moreover, thanks to the oil filling, the cases withstand the
water pressure at every accessible diving depth. All watches in this series
have a large black dial with white hands and 5-minute indices which are
particularly prominent at 12 o’clock (mission timer design), a case made of
seawater resistant German submarine steel and a captive diver’s bezel.
EZM 2B — THE MISSION TIMER MADE OF GERMAN
SUBMARINE STEEL FOR MARITIME USE
Reflection-free under water
thanks to HYDRO Technology.

German submarine steel guarantees seawater resistance
First-class material quality makes this diving watch completely resistant to
external influences. And the original German submarine steel guarantees
seawater resistance. This is precisely the steel used by ThyssenKrupp for the
external hulls of the U212 A class of the German Navy, which are currently the
most advanced non-nuclear submarines in the world. In addition to seawater
resistance, the steel is of the highest non-magnetic quality and is extremely
resistant to cracking.

19
TEGIMENT Technology and the Black Hard Coating
Because the captive diver’s bezel is subjected to extremely tough conditions,
we have additionally tempered the German submarine steel using TEGIMENT
Technology. With the aid of TEGIMENT Technology, we achieve greatly
increased scratch resistance through surface hardening. In our diving
watches with the Black Hard Coating, this tempering with the TEGIMENT
Technology forms the basis for the application of a high quality PVD coating.
We use the Black Hard Coating only in conjunction with the TEGIMENT
Technology.
The captive diver’s bezel
To protect against unintended adjustments, the diver’s bezel may only
be turned counter-clockwise and can easily be operated while wearing
diving gloves. Because the bezel plays a vital role in time measurement,
it is an extremely sensitive safety feature. That’s why we have protected
our bezel against loss with a special construction. Our secure attachment
differs significantly from the conventional snap-in mechanism: loss due to
unfortunate impacts is practically impossible, because the captive bezel is
securely fastened to the centre section of the case.
HYDRO Technology
Absolutely free from fogging, pressure resistant at any accessible diving
depth and perfect readability from any angle underwater – these are the
unbeatable advantages of our diving watches equipped with HYDRO
Technology. How does it work? The movement, dial and hands are immersed
directly in a crystal-clear bath of oil. The watch is thus free from fogging, as
there is no air inside the case.
