Silver Coach Watch by Johann Eusebius Loderer

Partially verified

This silver coach watch is a timekeeping instrument created between 1770 and 1776 by the German maker Johann Eusebius Loderer in Augsburg. It is a large circular piece measuring 11.8 cm in diameter, designed for portable use in a carriage. The object is fitted with a suspension neck and a large top ring threaded with a cord for hanging. The exterior of the silver case is worked in relief, displaying a complex mythological scene integrated with architectural and rocaille scrollwork. The composition includes a central seated female figure elevated on clouds, accompanied by a small child, a warrior holding a shield, and a male figure holding a caduceus, all positioned against a backdrop of columns and a seascape. Several small winding or mounting apertures punctuate the relief surface, and a thin cord extends from the bottom of the case. The watch is held in the collection of the Art Institute of Chicago.

Object description

Case Construction and Design

The watch is housed in a circular silver case measuring 11.8 cm in diameter. The exterior surface is extensively decorated with relief work that combines figurative scenes with rocaille and architectural scrollwork. These elements define the visual identity of the piece, anchoring it within its period of origin.

The configuration of the case includes a suspension neck topped with a large ring. This ring is currently threaded with a cord, indicating the method of attachment for the watch within a carriage environment. A separate, thinner cord is shown extending from the bottom section of the case, potentially serving a secondary functional purpose related to the timepiece's operation or mounting.

Several small apertures are distributed across the face of the relief work. These appear to function as winding or mounting points required for the watch's internal mechanical adjustment or external placement, demonstrating a practical integration of hardware into the decorative scheme.

Evidence for this section
  • “The circular silver case measures 11.8 cm (4 5/8 in.) in diameter and is fitted with a suspension neck and large top ring, threaded with cord.”
  • “The exterior of the silver case is richly worked in relief, featuring a mythological scene framed by architectural and rocaille scrollwork.”
  • “Several winding or mounting apertures are visible across the relief composition, and a thin cord extends from the bottom of the case.”

Figurative Composition

The relief ornamentation on the case front depicts a complex mythological scene. A central female figure is positioned seated, elevated on cloud formations. This central figure is surrounded by a group of associated characters that provide narrative depth to the design.

The scene includes a small child positioned near the central figure, a warrior figure holding a shield, and a seated male character holding a caduceus. These figures are set against a background consisting of architectural columns and a maritime seascape, which serves to unify the various elements of the composition within a cohesive frame.

Evidence for this section
  • “Visible figures include a central seated female figure elevated on clouds, accompanied by a small child, a warrior-like figure holding a shield, and a seated male figure holding a caduceus, set against columns and a seascape background.”
