„I‘ve always been fascinated by mechanical<br />
devices, and I can just look at my<br />
Time Machine for minutes on end,<br />
looking at the details of its construction.“<br />
Adam Rice, USA<br />
„My Time Machine immediately captives the interest of my visitors; they love to sit down and<br />
watch the motion. Initially, I had the hands installed then realized it is more about the rhythmic,<br />
sonorous regularity of passing time. As I observe, a small wheel moves a larger one,<br />
stimulating philosophical contemplation. The most amazing thing for me as a musician is that<br />
the sounds of the Time Machine have never disrupted my playing!”<br />
Clemens Goldberg, Musician, Berlin<br />
„I like the design and that it is art“<br />
Boris, Pilot, Switzerland<br />
„Fall in Love ...<br />
„My Time Machine can not turn<br />
time back or forth. But it lets me<br />
enjoy the presence!“<br />
„The sound of the Time<br />
Machine brings a little<br />
magic to each morning<br />
coffee.“<br />
Désirée Fischer,<br />
Marketing Manager, Switzerland<br />
Margrit Anliker Schlumpf, Switzerland<br />
„The work of art is at the heart of our hotel, in the<br />
reception area, where it is admired by many people<br />
every day, symbolizing the outstanding symbiosis of<br />
art and technology.“<br />
Fritz Erni, Director Art Deco Hotel Lucerne<br />
„The Time Machine has taken me from the<br />
beginning into magically timeless moments.<br />
She accompanies me - almost meditatively<br />
- out of everyday life. I find the contact with<br />
myself again - sonorous - not timed. „<br />
Franz Furmaniak, Bicycle Builder, Germany
„Schlumpf Time Machines elevate the notion of time to a level of art!<br />
Our TM4 is a stunning and inspiring eye-catcher in the entrance of<br />
our family office.“<br />
„Now our home is complete“<br />
Sandra Vazquez, Lawyer, Zurich<br />
Sulamith Semrad, Musician, Switzerland<br />
„I am privileged to have one of the<br />
first models at my home. Apart from<br />
loving the Time Machine ourselves<br />
it is a wonderful talking point for<br />
most of our visiting international<br />
friends. Above all it does NOT show<br />
the time!“<br />
Dick van Meurs, Woking, UK<br />
... at first sight“<br />
„The inspiring difference!“<br />
Dan Semrad, Architect, Switzerland<br />
„In 2015 we spent a nice little holiday in a nice hotel overlooking the<br />
stunning „Vierwaldstaettersee“. In the lobby was „ticking“ this impressive<br />
Zeitmaschine with deep sound. Every morning before leaving for the<br />
excursion I was watching „the machine“. And every evening the same<br />
ritual just before the aperitif to finish the nice day. So we fell in love with<br />
this nice masterpiece and decided to install one in our home alongside<br />
the nice river „Leie“ near Gent. Since then we enjoy the view and the<br />
sound every morning and every evening again, for many years to go. It<br />
brings quietness and peace!“<br />

TM3
<strong>SCHLUMPF</strong> TM3<br />
CONQUER THE WORLD OF TIME<br />
The Time Machine Collection consists of compositions<br />
celebrating the mechanical precision<br />
and sensory pleasure of a traditional clock in a<br />
purely artistic manner.<br />
Each variation exposes the inner workings of<br />
the clock mechanism and places the motion of<br />
each gear, spring, and axle in the spotlight.<br />
The TM3 runs for eight days driven by double<br />
spiral springs and axles supported by ball bearings<br />
with non-contact seals to reduce friction.<br />
This piece also incorporates patent-pending<br />
anchor arms built with spring-loaded technology<br />
providing smooth, almost silent operation requiring<br />
minimal energy.<br />
The suspension system transforms the kinetic<br />
energy of the movement to the spring so that very<br />
little power is wasted.<br />
In addition to the skeletonized appearance,<br />
the Time Machines are hand-finished in eyecatching<br />
colour palettes of black, silver or<br />
gold, which enhance their modern architecture.<br />
In either finish, each kinetic sculpture transforms<br />
a space both visually and audibly.<br />
Due to its light aluminium structure, the TM3<br />
weighs only 10 kg while measuring 1.3 meters<br />
(“Kaspar” & “Anna”) or 1.8 meters (“Johann” &<br />
“Paulina”).<br />

<strong>SCHLUMPF</strong><br />
TOOTH PROFILE<br />
TIME INDICATION OR TIME-<br />
LESSNESS<br />
The Schlumpf principle of the<br />
spring loaded anchor pallets<br />
is used on the small TM3, providing<br />
very smooth and nearly<br />
silent operation.<br />
The Time Machine runs on the<br />
energy contained in two spiral<br />
spring housings, that provide<br />
up to eight days of runtime.<br />
The springs are connected in<br />
series, so winding one gives<br />
power to both springs.<br />
Based on a Wildhaber-Novikov<br />
tooth profile, Schlumpf<br />
uses self-lubricating bronze<br />
bushings on hardened and<br />
high-polished pins.<br />
Schlumpf offers a selection of<br />
different hand designs. Classical<br />
(shown below) to modern<br />
or minimalistic.<br />
Hands are hold by magnets;<br />
simply click them on or off.<br />
The housings are geared on<br />
their outer side, one with a<br />
standard tooth shape, the<br />
other with bronze bushing on<br />
hardened steel pins, giving a<br />
nearly frictionless operation.<br />
On a standard escapement,<br />
all the kinetic energy of the<br />
wheelwork is lost, when the<br />
anchor pin hits the anchor<br />
pallet. With our special anchor<br />
pallets, the energy is stored<br />
in the spring steel material of<br />
the pin, and the energy flows<br />
directly into the swing of the<br />
pendulum at the next cycle.<br />
This reduces friction to the absolute<br />
minimum and completes<br />
the technical perfection of<br />
an outstanding mechanism full<br />
of ground-breaking solutions<br />
never seen in the world of<br />
clock making before!<br />

<strong>SCHLUMPF</strong> TM4<br />
CONTEMPLATE THE PASSING OF TIME<br />
The dynamic Time Machine TM4 by<br />
<strong>SCHLUMPF</strong> creates a dramatic portal into the<br />
universe of time by virtue of its size. Measuring<br />
approximately 2.2 x 2.2 meters, the bold, black<br />
filigree frame houses onyx black and golden<br />
anodized gears contrasting with a mirror – polished<br />
golden pendulum disk and hands. A striking<br />
component is the large 1.8 meter orbital drive.<br />
An anchor beam rotating around the central anchor<br />
wheel provides constant movement.<br />
„Sit back, watch the<br />
mesmerizing movement,<br />
listen to the sound<br />
of the pendulum<br />
and contemplate<br />
the passing of time“<br />
Although the isochronal sounds of the clock are<br />
alluring, the escapement uses spring–like anchor<br />
pallets, which produce smooth, virtually silent<br />
transitions. These models feature hands indicating<br />
seconds, minutes, hours, and day of week.<br />

THE ENGINEERING BEHIND<br />
ORBITAL DRIVETM<br />
The patent-pending mechanism<br />
provides a steady rotation<br />
of the wheelwork, while the<br />
anchor wheel is in a „stop-andgo“<br />
mode only.<br />
During rotation energy flows<br />
into the small sun wheel,<br />
which contains a spiral spring,<br />
and back to the anchor wheel.<br />
The steady motion leads not<br />
only to a powerful and wide<br />
pendulum swing but also to a<br />
very econo mic operation mode.<br />
PENDULUM SUSPENSION<br />
The pendulum rod with the<br />
big pendulum disk rests on<br />
two hardened and sharpened<br />
needles, which are hold in two<br />
hardened seats.<br />
One more refined detail of a<br />
sophisticated technique, that<br />
provides long life span and<br />
high efficiency.<br />
<strong>SCHLUMPF</strong> TOOTHING<br />
On the TM4, Schlumpf combines<br />
a conventional cycloidal<br />
gear with a special design of<br />
lantern cog: self – lubricating<br />
bronze bushings run on hardened<br />
and high – polished pins.<br />
SPRING LOADED ANCHOR<br />
PALLETS<br />
The patent-pending principle<br />
of the spring loa ded anchor<br />
pallets is one more big improvement<br />
in the clock history.<br />
While hitting the anchor pin,<br />
the pallet doesn‘t lose all the<br />
energy during the impact but<br />
conserves the driving force<br />
through a smooth tensioning<br />
of the pallet, which is made of<br />
high tech spring steel.<br />
One more contribution to a<br />
very effective and nearly silent<br />
operation mode!<br />
This reduces friction to the absolute<br />
minimum and completes<br />
the technical perfection of<br />
an outstanding mechanism full<br />
of ground-breaking solutions<br />
never seen in the world of<br />
clock making before!<br />

<strong>SCHLUMPF</strong> TM5<br />
AN ETERNAL KINETIC ART COMPOSITION<br />
The TM5 is an eternal kinetic art composition<br />
that transcends time by uniting contemporary<br />
design with the authentic traditions<br />
of Swiss timekeeping.<br />
noiseless motor periodically winding the<br />
springs that drive the machine and an escapement<br />
using spring-like anchor pallets, which<br />
produce smooth, virtually inaudible transitions.<br />
The rhythmic oscillation of the pendulum,<br />
exposed components of the skeletonized<br />
clock mechanism, and the sheer size of the<br />
piece measuring 1.2 x 1.2 meters converge to<br />
create a work of art with a powerful presence:<br />
its intricate design and constant motion<br />
deliver adroit, ever-changing artistry as the<br />
elegant wheels turn in time to the swings of<br />
the pendulum.<br />
The TM5 captures the true beauty of time,<br />
while simultaneously remaining a marvellous,<br />
kinetic work of art that enlivens any space from<br />
a boardroom to formal foyer.<br />
Thanks to its central structure made of highstrength<br />
aluminium, this animated work of art<br />
can be displayed on a wall with or without the<br />
bold frame enclosing the clock mechanism.<br />
Complementing this hypnotic sway is the<br />
steady movement of the oversized wheel and<br />
anchor beam of Schlumpf’s patent-pending<br />
Orbital DriveTM system.<br />
Choose to have the TM5 display minutes, hours<br />
and day of the week with magnetically positioned<br />
pointers. Or, move beyond precision by<br />
completely removing any indication of time to<br />
invoke timeless admiration, thereby revealing<br />
the TM5 in its purest form.<br />
While the modern architecture of the piece<br />
immediately draws the observer in by creating<br />
a mechanical and restlessly changing image,<br />
soothing acoustics of endless ticks and tocks<br />
enhance the connection with time.<br />
The isochronal sounds of the clock are the focus<br />
as the balance of the complex machine is otherwise<br />
virtually silent thanks to an almost<br />

THE ENGINEERING BEHIND<br />
ORBITAL DRIVE<br />
The patent-pending mechanism<br />
provides a steady rotation<br />
of the wheelwork, while<br />
the anchor wheel only is in a<br />
„stop-and-go“ mode.<br />
CLOCKWORK DRIVE<br />
The Time Machine runs with<br />
the energy contained in a „sixpack“<br />
of spiral spring housings,<br />
wound with a tiny electric<br />
motor from time to time.<br />
The tension of the springs<br />
regulates the turning-on of<br />
the motor and stops it, if the<br />
springs are fully wound-up.<br />
The TM5 is delivered with an<br />
external 110-230V power adapter<br />
to drive the internal 12V<br />
micro motor.<br />

SPRING LOADED ANCHOR<br />
PALLETS<br />
The patent-pending principle<br />
of the spring loaded anchor<br />
pallets is one more big improvement<br />
in the clock history.<br />
While hitting the anchor pin,<br />
the pallets don‘t destroy all<br />
the energy during the impact<br />

of a high tech spring steel.<br />
During rotation energy flows<br />
from the wheelwork into the<br />
small sunwheel on the anchor<br />
beam, which contains a spiral<br />
spring, and accelerates the<br />
anchor wheel periodically. The<br />
steady motion leads not only<br />
to a powerful and wide pendulum<br />
swing but also to a very<br />
economic operation mode.<br />
This reduces friction to the absolute<br />

an outstanding mechanism full<br />
of ground-breaking solutions<br />
never seen in the world of<br />

<strong>SCHLUMPF</strong> MONUMENTAL PROJECTS<br />
MOSCOW MONUMENTAL CLOCK<br />
In the year 2014, Schlumpf worked with<br />
the Russian Pedrodvorets Watch Factory<br />
to develop and build a monumental clock<br />
with a twelve-meter-long pendulum and<br />
cogwheels up to four meters in diameter<br />
for the traditional Moscow Detski Mir<br />
Warenhaus.<br />
This project unveiled many new technologies,<br />
one of them being the orbital drive, which<br />
allows the entire clockwork to move steadily,<br />
with only the anchor wheel stopping intermittently<br />
so as to preserve the kinetic energy of<br />
the movement.<br />

Its five meters size was big enough to walk<br />
through, inviting the visitor to listen to the<br />
magical sound of four identical but non-synchronous<br />

MONUMENTAL PENDULUM SCULPTURE<br />
<strong>SCHLUMPF</strong> products have always<br />
attracted attention and admiration.<br />
Marvellous speaks to the power of<br />
fascination, creating a captive moment<br />
that lets us transcend from the mechanical<br />
tick-tock to a state of admiration<br />
for life and everything it has to offer.<br />
We derive our energy from marvelling,<br />
of being stopped in wonder of how the<br />
impossible is made possible.<br />
To us, marvelling us is much more than<br />
the fascination of indulging in the seductive<br />
movement of our Time Machines.<br />
For us, marvelling is deeply rooted in the<br />
admiration of all that is beautiful: Past,<br />
present and future!<br />
We marvel at our ancestors, of how they<br />
have overcome obstacles and found ways<br />
to innovate and create the great mechanical<br />
master pieces of their time.<br />
We admire technological advancements as<br />
much as we enjoy the power of presence.<br />
From the majestic and panoramic scenes<br />
in Trimmis to the beautiful environments<br />
our Time Machines are placed in.<br />
With this background, innovative projects<br />
are being created. One of them is<br />

We achieve this through the design<br />
and development process, taking place in<br />
the Swiss workshop, which is primarily<br />
guided by intuition.<br />
Florian Schlumpf, creator and founder,<br />
engineer and artist with degrees in both<br />

palettes of black, silver, copper, or gold, which enhance<br />
their modern architecture. Whether standing on its own<br />
or hanging on a wall, each kinetic sculpture transforms<br />
a space both visually and audibly.<br />
The statuesque TM1 model, rooted on a disk-shaped<br />
floor plate, stands more than two meters tall (6.5 feet),<br />
elongated by a steel frame bringing its total weight to<br />
an impressive 80 kg. This dominant vertical structure<br />
features a timing mechanism consisting of four pairs<br />
of gears and an escape wheel measuring an incredible<br />
500mm in diameter. The meditative swing of the<br />
TM1‘s pendulum remains in operation for half a week<br />
without a fresh injection of energy.<br />
