This movement first lived in a gold case that at some point during its 120 plus years life was melted down for its scrap value. The surviving movement remains a living memory of watchmakers time spent over a century ago to produce a very high-end timepiece.
Gruen & Sons precision pocket watch movement from "Gruensche Uhrenfabrikation Gruen and Assmann" manufacture in Glashütte. Here, precision pocket movements were manufactured according to Glashütte quality standards called "Fortschritt" for the USA.
Production of this calibre began in November 1894 with the serial number 62000 and ended around 1897 with 68000, a total of six thousand movements were made.
The movement was made from German silver.
The end piece for the Swiss anchor, escape wheel, centre wheel, jewel chatons were all made in red gold.
The anchor was angled and polished manually.
The hidden side of the anchor was also angled and straight grained.
The over-coil of the balance spring was held in place by an elegant single screw stud system.
The regulation snail cam upon which the regulating index is pushed by a spring, is finely adjusted by the small piece to its left meshing with the wheel fixed under the snail cam.
The impulse jewel fixed directly into the balance wheel and a gold safety roller pushed onto the balance staff.
One of the timing screws for the balance, also made in gold.
