What is it that connects people with time? Both are perpetually in motion. As the famous proverb says, ‘a rolling stone gathers no moss’, which reminds us of the benefits of an active lifestyle. This takes energy. Mechanical watches have been wound by hand for centuries – b y turning a crow n, a crank, a key or b y hoisting weights on a chain. How can we fulfil the dream of a mechanism that makes consciously winding the watch superfluous? The answer is given by man himself. The movement of the watch wearer supplies the self-winding watch with the energy it needs.
Grossmann’s aesthetics – interpreting the traditional automatic hammer makes the most beautiful mechanics come alive
The
HAMATIC Vintage draws its kinetic energy from the arm movement of the watch wearer. The movement of the arm continuously deflects a pendulum in the shape of a hammer with a heavy gold hammer head. This kinetic energy is transferred via the ratchet wheel to the mainspring in the barrel and winds the watch.
Inspired by the vintage idea, the
Moritz Grossmann designers adopted the traditional concept of an automatic hammer winding system from the 19th century and refined it according to the principles of Grossmann’s supreme craftsmanship, resulting in a new movement.

The elaborate design of the hammer mechanism, known as the
HAMATIC for short, provides a stage for the strikingly crafted gold hammer head and reveals the fascinating mechanics and exceptional finish of
Grossmann’s
106.0 movement. The oval hammer body is open in the middle, offering a clear view of the beauty of the highly sophisticated mechanism.
Vintage style dial with shiny black-or surface
The new version of the
HAMATIC in
750/000 white gold comes with a vintage style dial and is
limited to
25 models worldwide. The dial has been given a new and exclusive finish. The surface was first painted in a black-anthracite colour. The mirror-polished background on a German silver base was then treated with a finish called ‘black or’, which created a shiny black surface.

Large Roman numerals in white form an attractive contrast to the black dial of the
HAMATIC Vintage. The vintage
‘M. Grossmann’ logo from
1875 and handcrafted polished – hand s m easuring a m ere
0.1 mm wide are an homage to the old pocket watches of
Moritz Grossmann.
Calibre 106.0 – Bidirectional automatic hammer winding mechanism transfers even the slightest arm movements to wind the mainspring
The calibre
106.0 was especially designed for the
HAMATIC. This classic pillar movement has a
2/3 plate and six Glashütte stripes.

The hammer winding mechanism works in two directions and winds the watch, regardless of the direction in which the watch wearer moves his arm. The winding mechanism via two click wheels is also highly energy efficient. The alternating, even winding over both wheels ensures that the mechanism is highly reliable. A power reserve of 72 hours is available when the movement is fully wound, which means that the
HAMATIC continues to run for three days without any further movement.

Another advantage of the hammer-style pendulum system is that the hammer’s centre of mass is further away from its rotational axis in the
HAMATIC. This results in a high torque, which means a powerful force acting on the spring.

Hammer movements from just five degrees, which correspond to an
oscillation of 2 mm, are used to wind the mainspring. The constant
winding when the watch is worn also ensures that the spring is evenly
tensioned, thus ensuring a high degree of precision.
Compensating for quick and slow movements by means of stop springs
The
newly designed movement offers a further advantage. People do not
always move in the same way. Movements are fast and slow. The former
generate excessive deflections of the hammer body, which need to be
attenuated and limited by fixed end stops.

This shock absorption is
ensured by intricately crafted end springs in the hammer frame. More
gentle movements, on the other hand, result in a lower hammer amplitude.
Friction losses are virtually non-existent and energy transmission is
nearly loss-free.
Reduction gear with yoke winder manual or automatic winding of the movement possible
In
order to achieve a continuous rotary motion of the wheels for winding,
the oscillations of the hammer body are picked up by two click levers
and transferred to two click wheels. The two-way direction of rotation
of the click wheels ensures an even rotary motion. This transfers the
energy to the ratchet wheel in the mainspring barrel via the free wheel.

The watch can be wound by hand in addition to the self-winding
mechanism. To achieve this, a manual winder designed as a yoke winder is
mounted on a separate bridge. The yoke ensures that the manual winder
is always uncoupled from the ratchet wheel when the
HAMATIC system
is active in response to motion. In manual winding mode, the reduction
gear is isolated from the ratchet wheel by the click-pawl idler.
The
HAMATIC also offers a stop-second function via the balance for ultra-precise time setting.
