Object description

Dial Configuration and Visual Features

The open-face dial is white enamel and signed 'AGASSIZ' beneath the arbor. Time is indicated by black Breguet-style Arabic numerals alongside an outer minute track marked with red five-minute intervals.

Two subsidiary registers are aligned along the vertical axis: a 30-minute register at 12 o'clock and running seconds at 6 o'clock. The silver case is fitted with a fluted winding crown and bow at 12 o'clock, with an auxiliary actuator push-piece visible near 11 o'clock on the case band.
