1963 Solid 18k Gold Omega Constellation Dennison Cased 1685415 on Solid Gold Omega Milanese Bracelet in Original Constellation Box

An 18k gold Omega Constellation watch paired with its original 9k gold Omega (made by David Shackman & Sons (DS&S)) bracelet is a specific configuration common for British-market watches, particularly during the 1960s and 1970s. This setup often resulted from importing high-grade Omega movements into the UK, where they were cased and bracelet-matched by local manufacturers like DS&S to avoid high import taxes on finished jewelry, or simply to suit local tastes and durability requirements. 

Key Details regarding this Configuration:

• The 9k solid gold Milanese Bracelet is in perfect condition and was made by (DS&S): David Shackman & Sons (DS&S) who were highly reputable British case makers and suppliers to Omega who frequently created solid 9k gold bracelets for high-end Swiss watch brands, including Omega, Rolex, and Longines in England to avoid high Import Duties on Gold into England at the time;
• Gold Composition Difference: The watch case is made of solid 18-karat (750) gold, which is more yellow and lustrous, while the bracelet is solid 9-karat (375) gold, which has a slightly darker, softer, and more muted yellow hue. This difference is common in vintage UK-market pieces to give greater strength and reliability to the bracelet whilst preserving the overall solid gold look;
• Origin: The watch movement is Swiss, but the case was made by renowned Birmingham Case makers Dennison and son and the bracelet was made in London by DS&S under licence from Omega and officially Omega branded;
• Era: These configurations are frequently found in vintage models from around 1960 to 1970
• Value and Appeal: Such pieces are highly regarded by collectors, especially when the bracelet is original to the watch and in such good condition.
