Omega 18-karat Yellow Gold Art Deco Pocket Watch

Partially verified

According to the seller, this open-face pocket watch was produced by Omega in Switzerland during the first half of the 20th century, likely around 1920–1930. The 18-karat yellow gold case measures 4.5 cm in diameter with a gross weight reported at 56.7 grams. The two-tone Art Deco dial combines a brushed silvered chapter ring with elongated black Arabic numerals and a center alternating vertical gold and silver bands. A subsidiary seconds dial at 6 o'clock contains a sunken gold-toned center signed OMEGA below the brand emblem. The seller describes an engine-turned case back and a jeweled manual-wind anchor movement.

Case Construction and Decorative Elements

The timepiece features an 18-karat yellow gold case (750/1000) with a diameter of 4.5 cm and a gross weight of 56.7 grams. The case includes two internal gold flaps, and the exterior back displays an engine-turned (guilloché) pattern with oblique fluting, bordered by gadrooning.

The winding crown and the bow (lugs) incorporate a stylized foliage motif. While the seller claims the case bears hallmarks and serial numbers, these marks are not captured in the provided source documentation or imagery.
