Object description

Case and Dial Design

The watch is housed in a hunting case measuring 52mm in diameter. It is constructed from sterling silver and features applied multicolored gold decorations. The exterior of the case is divided into two distinct motifs: the front cover is adorned with botanical patterns and flowers, surrounding an empty shield intended for personalized engraving. The rear cover depicts a detailed engraving of a locomotive train.

The dial is a double-sunk white model designed for high legibility. It utilizes black Arabic numerals for the hours. To facilitate time reading, the outer edge of the dial features minute markers printed in both black and red. The watch is fitted with spade-style hands in black, which contrast with the white background of the dial.
