Design

Dial and Hands
The watch features a silvered dial with applied hour markers, an Omega signature, and slender hands, all noted as appearing original. The dial exhibits signs of age around the edges, including intermittent small black spots. The hour markers, Omega signature, and hands have developed a light patina. The hands exhibit minor signs of wear with small scratches observed at the base.
Visible features
• Square inner case suspended inside a cut-out outer frame with textured Florentine finishing. • Silvered dial with applied golden baton hour markers and 'SWISS MADE' printed at 6 o'clock. • Dark brown leather strap with contrast red-brown stitching. • Fluted winding crown positioned at 3 o'clock within the open frame structure.
Case Construction
The timepiece features a 14k gold square case with an openwork, floating frame design. The exterior surfaces exhibit a Florentine-style textured finish. The case is described as being in good condition with light scratches, and some small nicks present on the bezel, case back, and the 3 o'clock side near the crown. A hallmark is present and described as crisp on the case back.
Movement and Maintenance
The watch is powered by a manual-wind Omega caliber 620 movement. The interior of the case back features historical watchmaker's marks. At the time of cataloging, the movement was observed to be in working order; however, it has not been tested for accuracy, and a service is recommended.
