ROLEX VINTAGE LADIES CUSTOM JEWELLERS CASE 9 CARAT

Rolex vintage ladies' watch housed in a custom jeweler's 9-carat gold case, likely from the early to mid-20th century. Rolex was known for supplying movements to be housed in custom cases, often made by independent jewelers, especially for ladies' watches during this time.
Key Features Supporting the Era:
1. Dial Design: Roman numerals, enamel dial, and red "XII" were common in watches from the 1910s–1920s.
2. Case Material: 9-carat gold suggests it was custom-made in the UK or a market where 9-carat was popular.
3. Movement: The exposed mechanical movement and style are consistent with early Rolex wristwatches.
4. Crown Design: The floral-style crown is another characteristic of early ladies' wristwatches.
Additional Context:
Rolex transitioned from making pocket watches to wristwatches around this time, often with cases provided by local jewelers. This practice was especially common in the UK and other Commonwealth countries.
