Blancpain. A fine and rare 18K gold and citrine ring watch

The present ring watch is distinguished by the unusual use of a faceted yellow citrine instead of the commonly found crystal or glass.

Citrine is a transparent, yellow variety of Quartz, ranging in colour from pale to golden yellow, honey or almost brown, and may contain rainbow or sparkle inclusions. The name comes from the French word citron, meaning lemon.

The case of this very elegant and boldly designed example was made by the Geneva master casemaker F. Baumgartner, whose punch mark of number 2 in a key is found inside the back. Baumgartner made cases for Patek Philippe watches including the reference 2526.

Ring watches have always been greatly fascinating due to their small size and ingenuity to be set into a small piece of jewellery. Production of these pieces requires exceptional skill and they are therefore usually only executed by the best watchmakers and jewellers.
