GRUEN PRECISION Technology
FRED GRUEN designed 1892 the very first GRUEN watch as masterpiece at the GLASHÜTTE i. SA. - UHRMACHERSCHULE
DIETRICH GRUEN Glashütte i. Sa. - Precision - Technology
The successful historical GRUEN - ASSMANN cooperation from 1894, including the exclusive MORITZ-GROSSMANN escapement, was both an incentive and an obligation for the GRUEN company later on.
Then as now, the success story of fine mechanical watches has to be continued by creating consistent classic values, true to the DIETRICH GRUEN manufacturing principle, at a high level of watchmaking art and product quality.

ABOVE: GREEN PRECISION escapement constructed by Moritz Grossmann . The engraving in English names the precision controls of the watch = depending on the heat. Cold, isochronism (http://www.uhrenlexikon.de/begriff.php?begr=Isochronismus&nr=3) and carrying positions (from 2-6) for an average value that is normal in daily use. http://www.uhrenlexikon.de/begriff.php?begr=Reglage. The DRESDEN engraving shows a stylized G in the middle around the S - for Glashuette as the place of manufacture.

In view of the increased costs, only a few premium manufacturers later bought the products during MORITZ-GROSSMANN's lifetime in Glashütte i. MORITZ - GROSSMANN - GRUEN - PRECISION escapement developed in Saxony and built by D. GRUEN & SON from 1894 and adopted as an escapement principle for special precision watches.
It is known that after 1900 the Mustache anchor (balance anchor) were used in precision watches at PATEK PHILIPPE, among others, in the CHRONOMETRO GONDOLO line, especially in sales to South America via the Brazilian jewelry chain Gondolo & Labouriau from Rio de Janeiro, which was then sold to PATEK PHILIPPE & Cie. Which were financially involved and had exclusive rights for PP distribution.
See below: The similarity of the PP gear unit + fine adjustment to the Moritz Grossmann / GRUEN design is remarkable. At that time, PP built the balance-anchor escapement, with and without eccentric fine adjustment, for a number of early Patek Philippe wristwatches and other Patek Philippe pocket watch models.

The classic manufacture wristwatch from Glashütte i. Sa. shows more than time; - it is timeless jewelry, an investment and a lifestyle symbol

The exclusivity of manufactured watches is based on the fundamental difference to electronic mass-produced goods. The manual production of watches does not allow mass production, but then as now, exclusive individual movements are created, especially with individual engraving. A classic Glashütte watch is something like a noble organism that the watchmaker awakens to a long life by hand, with the customer in mind; - e.g. B. like the first GRUEN-PRECISION pocket watch No. 32,000 from 1894. >>>
