Object description

Case and Aesthetic Design

The watch is housed in an 18K yellow gold case measuring 39mm by 26mm, referred to as a jumbo model for its period. The design, described as a 'Stingray' case, is characterized by its sweeping, flared sides, which intended to create a sense of movement and visual tension when worn on the wrist.

The construction reflects the geometric and streamlined architecture prevalent in the 1930s. The manufacturer utilized these bold forms to distinguish the piece from traditional round pocket-watch conversions, aiming to align the aesthetic with the era's industrial design motifs.
