J. Assmann

Ingenieur - Genaue Zeit

A silver Glashuette marine deck watch with display stand; this stand was specially designed for this Assmann marine watch. It is equipped with a spring suspension that prevents any movement of the watch and ensures an excellent timekeeping result, guaranteeing a maximum permissible timekeeping deviation of only 15 seconds per month. This is why this watch is originally called "Genaue-Zeit-Uhr" (exact time watch)

Sold

This exceptionally well-preserved deck watch has a Swiss pallet lever escapement with counterpoised "Moustache" lever, designed as a showcase watch.
Many notable watch brands provided their authorized dealers with timepieces that were intended to be presented in shop windows or display cases purely for advertising. The watches were not for sale and produced in very small series.

The "Ingenieur" series was identical in construction to the J. Assmann naval deck watch with bridge movement but was aimed at the civil market. These precision timepieces were used in many research facilities and industrial businesses for exact timekeeping during scientific and industrial processes. Institutions such as the Königliches Astrophysikalisches Observatorium (Royal astrophysical observatory) and the Königliches Geodätisches Institut (Royal geodesic institute) in Potsdam possessed several of these B watches. The bridge movement used in this model is a custom-made series of ebauches produced by Swiss company LeCoultre & Cie. Which was delivered on order to J. Assmann after 1902. The ebauches received extensive finishing and fine adjustment in Glashütte, so that they certifiably adhered to the the Glashuette standard, which is still valid today.
