Moritz Grossmann Gives the Hamatic a Black Enamel Dial

Moritz Grossmann’s Hamatic has always been a watch for people who like their mechanics visible, unusual and rooted in horological history.

For the latest anniversary edition, the Glashütte manufacture gives that eccentric automatic system a more formal stage, pairing its pendulum-style hammer winding movement with a jet black enamel dial in rose gold and white gold cases.

The release forms part of the brand’s wider celebration of Carl Moritz Grossmann, born in 1826, whose name remains closely tied to Glashütte’s development as a centre of German watchmaking.

At a glance

• Moritz Grossmann has introduced two Hamatic Enamel anniversary editions with jet black enamel dials.
• The watch is powered by the in-house calibre 106.0, an automatic movement wound by a pendulum-style hammer weight.
• The rose gold and white gold versions are limited editions priced at EUR 63,500 excluding tax.

A black enamel dial for a very German complication

The Hamatic’s main event sits on the back of the watch, but this edition makes a strong argument for spending time with the dial side first.

The jet black enamel dial is made using ground glass mixed with metal oxides, fired repeatedly in a kiln to create its glossy depth and durability.

Against that dark surface, Moritz Grossmann has used applied Arabic numerals in white gold or rose gold, depending on the case metal.

That marks a shift from earlier Hamatic models with Roman numerals, giving these anniversary pieces a cleaner and slightly more contemporary face without losing the old-world character of the watch.

The familiar details remain, including a peripheral railway-style minute track, a slightly recessed small seconds display at 6 o’clock and the brand’s handmade polished hour and minute hands in steel or rose gold.

The M. Grossmann signature also carries a historical cue, with lettering that emulates an 1875 typeface as a tribute to the founder.

The hammer automatic seen from the back

Introduced in 2018, the Hamatic is built around a winding system that looks back to early perpetual mechanisms used in pocket watches by Breguet and others in the late 18th century.

Instead of a conventional rotor turning through 360 degrees, Moritz Grossmann’s in-house calibre 106.0 uses a hammer with a solid gold mass at its end.

That hammer swings through a short arc, pendulum-like, to wind the mainspring and provide a 72-hour power reserve.

The openworked construction leaves much of the movement visible, including the Saxon German silver two-thirds plate, broad Glashütte ribbing, raised gold chatons and violet-annealed screws.

The balance cock is cantilevered and engraved by hand, with the year 1826 included in honour of Carl Moritz Grossmann’s birth year.

The movement runs at 21,600 vibrations per hour and uses an in-house Grossmann balance with four inertia screws and two poising screws.

Anniversary context and Glashütte heritage

Carl Moritz Grossmann was born in Dresden in 1826 and later established a mechanical workshop in Glashütte after encouragement from his friend Ferdinand Adolph Lange.

His reputation was built across specialised watchmaking tools, pocket watches, marine chronometers and precision pendulum clocks.

He was also a co-founder of the German School of Watchmaking, placing him among the figures who helped shape Glashütte’s technical culture.

That context suits the Hamatic especially well, because the watch is not merely a decorative anniversary piece but a modern interpretation of an older winding idea.

Details & Specifications

The Hamatic Enamel is likely to speak most clearly to collectors who value mechanical oddity as much as finish, and who prefer German watchmaking when it shows both discipline and a little eccentricity.

With its black enamel dial and visible hammer winding system, it’s a quietly theatrical anniversary piece rather than a safe commemorative rerun.
