Meister Chronoscope Terrassenbau: 
the anniversary watch

A mirror of history: to mark the centenary of the architectural master-piece by Philipp Jakob Manz, Junghans presents the limited Meister Chronoscope Terrassenbau.

The terrace building in Schramberg is one of the most spectacular industrial buildings worldwide to be built on a sloping site. At the beginning of the 20th century Junghans was the largest clock manufacturer in the world: demand for Junghans timepieces was so great that there was an increasing requirement for workplaces in the already cramped valley in Schramberg. The nine-stepped terrace building was built directly on the slope, in less than two years.

As a result, from 1918 onwards each watchmaker could benefit from direct daylight at the workplace. For decades, the building was the centrepiece of the Junghans factory. In the heyday of mechanical move-ments in the 50s and 60s in particular, numerous calibres were developed in Schramberg. Com-ponents were manufactured in the building to the front of the site, with calibre and watch as-sembly in the terrace building. The top floor was reserved for work that called for the utmost concentration, time and absolute dedication from the watchmakers: the assembly and regulation of chronometers.

2018 sees the monument of industrial architecture celebrate its 100th birthday, with 100 years of architectural history commemorated with a very special timepiece – the limited edition Meister Chronoscope Terrassenbau.

With a limited edition of 100 pieces, the Meister Chronoscope Terrassenbau features a 18-kt. gold case. Inspiration for the champagne-coloured dial with the three matt silver totalisers were the stair-ways of the terrace building, which are in beige and white.

The stainless steel version is limited to 1,000 watches and has a matt silver-plated dial.

Both models incorporate the distinctive elements of the industrial monument in Schramberg into their design: the minute track of the dial reflects the meandering design of the wall decorations in the terrace building, whilst the dark green of the wall tiles in the stairways can be found in the alligator leather strap. The case back delivers a direct view of the architectural work: an engraved image of the terrace building.

The Meister Chronoscope Terrassenbau – a masterful timepiece as homage to an architectural masterpiece.

The Junghans Meister range: inspiration from tradition

Meister – a label that stands for an entire Junghans watch range. The balanced design of the dial with its harmonious proportions has been a characteristic of the Meister line since the 1930s, together with the best movements produced at the company. In the 1950s the watch designers addressed the challenge of reducing the volumes of the watch and creating intricate timepieces, despite the relatively high movement.

The steeply domed glasses and dials in combination with thin-walled cases lent the watches a new, elegant and graceful look. During this time Junghans was also producing numerous mechanical calibres, such as the chronometer calibre J83, one of the finest movements to be manufactured in Germany.

The design of the Meister collection con-tinues to delight with the grace of its historical predecessors to this day. The models are an homage to the design philosophy and technical achievements of that era. Modern technology, exciting proportions and elegant lines are still features of these Junghans classics today.

Moritz Grossmann – ATUM ‘Backpage’ 41mm


Moritz GrossmannATUM Backpage’ Gold & Platinum 41mm 10th Anniversary Edition

Moritz Grossmann presents the
ATUM Backpage

Impeccable finishing – seen on the wrist

Until today, most of the highlights of a Moritz Grossmann calibre could only be admired on the caseback side of the watch. The development of the calibre 107.0, makes them visible on the dial side for the first time.

This new calibre is a mirror image of calibre 100.1 but has been redesigned for reverse rotation so that the movement can sit ‘upside down’ in the case. An generous aperture in the dial then exposes characteristic movement details such as the Grossmann balance, the hand-engraved balance cock and the 3-band snailing on the ratchet wheel – all without taking the watch off the wrist.

Calibre 100.1
---------------------


Two versions have been produced, in rose gold with a grey dial, and in platinum with a blue dial.  In each case, the dial presents a full minute scale and an hour display from 11 to 5 o’clock to frame the glittering calibre presentation.  Gold hour markers and numerals match the case colour.

The recessed small seconds ring has an extravagant bearing for the second hand featuring a gold chaton.

Calibre 107.0

Calibre 107.0 is essentially a mirror image of the calibre 100.1, but with crucial new design elements.  An additional wheel between the crown wheel and the ratchet wheel reverses the entire drive train with respect to the rotation of the mainspring barrel.  The wheel train runs in the right direction thanks to the mirrored escapement and the mirrored oscillation system – also including the balance spring coiling direction.

The larger dimensions of the 2/3 plate necessitated design changes for the balance cock and the escape-wheel cock. The cantilevered geometry of the escape-wheel cock creates a balanced accent in the overall arrangement of the movement. The High-Artistic finish showcases attractive hand engravings, bevels, and chamfers.

The minute-wheel bridge

To achieve the desired presence of the winding wheels on the dial side, the dial train was reconfigured. The artistically finished train wheels were arranged beneath a lavishly polished minute-wheel bridge. Since in this case, the hand-setting mechanism is located on the opposite side of the movement, the setting wheel extends all the way through the calibre.

The new arrangement created space for the optimised barrel bearing and the ratchet wheel, which was also shifted to the front side.

The winder with pusher and stop seconds

On the new rear side of the movement, the winding and hand-setting mechanism is now openly integrated in the train bridge, so its functionality can be fully observed for the first time. The stop-seconds and stop-balance functions have been redesigned as well.

In the hand-setting mechanism, the brake position is sampled at the clutch lever and, via a push rod, transferred to the brake spring, which then stops the balance.

After the pusher is activated and the movement starts, the brake spring returns the push rod to its rest position.

The platinum version is limited to 18 pieces to celebrate our 2018 10th anniversary.
