The independent manufactory from Glashütte gives a historic technique the chance to shine with the ONLY WATCH MORITZ GROSSMANN, combining the best of two birthday models for the Only Watch charity auction in 2021

  • A unique piece created exclusively for the Only Watch auction featuring a traditional silver-plated by friction dial according to age-old tradition
  • Highly finished calibre 100.1 with hand-engraved solid gold balance cock
  • Manually crafted, brown-violet annealed lance-shaped hands
  • The new model is a happy marriage of two past highlights – the silver-plated by friction dial of the XII Birthday Edition (limited edition for the twelfth anniversary of the manufactory) and the solid gold balance cock of the BENU Anniversary Unique (unique timepiece for the tenth anniversary of the manufactory)

The independent Glashütte manufactory Moritz Grossmann brings a piece of history to the ninth Only Watch benefit auction with a superbly crafted, unique timepiece. The auction takes place on 6 November 2021 in Geneva.

Under the patronage of His Serene Highness Prince Albert II of Monaco, Only Watch auctions exclusive one-of-a-kind watches from prestigious manufacturers every two years in aid of the Association Monégasque contre les Myopathies. The proceeds will be used to treat children suffering from muscular dystrophy and to advance research into the hereditary neuromuscular disease, which is currently considered incurable.

Moritz Grossmann is supporting the non-profit association for the third time and has again crafted a truly unique example of Glashütte watchmaking.

The dial adds to the undeniably elegant appeal of this unique piece of jewellery. It boasts a silver-plated by friction technique painstakingly finished by hand, a traditional art that ensures the time display can be read easily at all times and perfectly complements the distinctive appearance.

Another splendid statement comes in the form of a solid gold balance cock, elegantly catching the eye in the highly finished movement.

Silver-plating by friction – a traditional and rare finishing practice with unparalleled radiance

Only a handful of skilled artisans still master the sophisticated art of silver plating by friction today. And is what makes dials with this surface finish so extraordinarily unique. This traditional finishing technique from the 19th century was used by the gifted Glashütte watchmaking pioneer Moritz Grossmann during his lifetime for example in his high-quality pendulum watches.

The dial of the ONLY WATCH MORITZ GROSSMANN in Glashütte has been friction silver-plated by master craftsmen and brought into the modern era in honour of the Only Watch 2021. Embellished with large Roman numerals, the dial of this unique timepiece also bears the original ‘M. Grossmann’ logo from 1875.

Manually crafted lance-shaped hands in an annealed brown-violet hue are a nod to traditions of the past.

Silver-plating by friction is an exceptionally intricate form of finishing the dial, which creates a fine-grained yet velvety surface. It reflects the incident light without dazzling, ensuring that every minute detail of the dial can be read with ease.

This craft may well be almost two hundred years old, but the process has remained the same. A whitish powder consisting of silver granules, salt and tartar, is rubbed onto a previously roughened and meticulously cleaned and degreased brass sheet using a little water and a small brush. All the engravings are filled with lacquer beforehand, then fired in a kiln to avoid excessive silver build-up.

The surface is sanded to roughen it, which also removes any excess lacquer, so that only a deep black inlay remains in the engraved areas. As the silver powder does not adhere to the lacquer, the engravings and numerals are left out of the silver plating process, which means they retain their deep black colour and create an optimal contrast to the bright silver background.

The dial is finished with a protective coating to protect the high-quality silver-plating by friction from oxidation and other environmental influences in the decades and centuries to come.

The calibre 100.1 with hand-engraved solid gold balance cock

As with all timepieces from the house of Moritz Grossmann, the distinctive outer appearance reflects the superb mechanical workmanship that ensures precision on the inside.

The ONLY WATCH MORITZ GROSSMANN is powered by the calibre 100.1, visible in all its beauty through a sapphire crystal back. The Grossmann balance appears in the curved plate cut-out and is borne by the cantilevered balance cock with fine micrometer screw.

To do proper justice to the special occasion, the balance cock is made of solid gold. True to the finest Glashütte tradition, the piece is decorated with tiny floral motifs executed by master craftsmen.

The hand-wound movement gleams in the manufactory’s luxurious High Artistic finish. The 2/3 plate is accentuated by the typical broad, horizontal Glashütte ribbing. Raised gold chatons and pan-head chaton screws are a testament to the high quality and underline the filigree architecture of the movement. Fascinating reflections of light are created by the extraordinary depth of the contours and is the result of chamfers on drive wheels and edges of levers polished by master hands.
