Object description

Case and Dial Construction

The clock is designed as a pyramid, with the primary structure composed of lacquered brass and panels of lapis lazuli. The geometry of the case culminates in a faceted top. A transparent acrylic crystal covers the dial area, following the slope of the pyramidal design.

The dial itself is formed of lapis lazuli, providing a deep blue, textured backdrop for the time display. Surrounding the center is a brushed brass rehaut, which serves as the mounting point for the hour markers. These markers alternate between Arabic numerals at the quadrants and simple wedge-shaped indices for the remaining positions. The time is read via a pair of dauphine hands that match the brass finish of the rehaut.

Evidence for this section
  • “Housed in an 8” x 7.4” x 5.25” lacquered brass and lapis lazuli pyramidal case”
  • “it features a lapis lazuli dial with a brushed brass rehaut featuring quadrant ‘Arabic’ and ‘wedge’ indices, a matching ‘dauphine’ handset”

Movement and Functionality

The clock is driven by a hand-wound, 8-day movement manufactured by Jaeger-LeCoultre. This movement provides a power reserve intended to last for eight days between manual winding cycles.

Operational controls for the clock include a brass winding crown and a corresponding brass winding key. These allow the user to maintain the spring tension required for the clock to function throughout its stated reserve period.

Evidence for this section
  • “Powering the clock is a hand-wound, 8-day movement from Jaeger-LeCoultre”
  • “with a brass winding key, a brass winding crown”

Included Presentation
