A Refined and Elegant 1970s Gents Omega Dress Watch in Solid 14k Gold – Featuring a Rare Ross Case (US MARKET)

A beautifully understated vintage Omega dress watch from the 1970s, housed in a solid 14k yellow gold case made by the respected American casemaker Ross Watch Co., who supplied Omega with cases for the U.S. market. The 34mm case is refined and balanced, capturing the elegance and minimalist sophistication that defined Omega’s golden era of watchmaking.

Inside ticks the Omega Calibre 625, a manual-wind movement introduced in the early 1970s and part of the trusted 620 series. With 17 jewels, a frequency of 21,600 vibrations per hour, and a power reserve of approximately 42 hours, it is known for its slim profile and reliable performance. The movement has been recently serviced and is running accurately.

The dial is particularly striking — a warm, brushed champagne tone with applied gold stick hour markers. The 12, 3, 6, and 9 markers feature subtle black enamel tops, adding just the right touch of contrast and character. Complementing the dial are the original gold-tone stick hands.

Paired with a premium Hirsch leather strap, this watch offers both comfort and timeless style. It has been fitted with a new acrylic crystal and was lightly polished to preserve its original lines while enhancing its appearance.

Ross Watch Case Company – Deep Background

Location & Timeline:

• Founded in the early 20th century in the United States.

• Based in Brooklyn, New York.

• Active primarily from the 1920s through the 1950s.

• Became a key supplier for American market Omega watches, especially during and after WWII.

Why American-Cased Omegas?

• Due to import tariffs and gold import restrictions in the U.S., Swiss brands (including Omega) often shipped uncased movements to North America.

• These movements were then cased locally by American firms like Ross, Wadsworth, Star, and Dennison (UK).

• Ross specialized in high-quality gold and gold-filled cases, including 10K and 14K varieties.
