Abstract: A watch case assembly having a main casing of substantially ring-like configuration, a stainless steel movement retaining ring attached within the bottom portion of the main casing, a gold rear wall retaining ring attached to the movement ring and a stainless steel rear wall attached to the rear wall ring. The rear wall ring extends outwardly from the movement ring abutting the maining casing and inwardly from said ring providing a surface for attaching the rear wall. When positioned on a wearer's wrist only the stainless steel rear wall engages the wearer's skin and only the main casing and the rear wall ring are visible and as a result the casing appears to be entirely gold.
