LONDON.- A unique and impressive 18 carat gold and diamond gentleman’s skeleton wristwatch by the Swiss luxury watchmaker Corum is estimated to sell for £100,000-150,000 as part of Roseberys Fine Art auction on Tuesday 24 March.

Commissioned and designed exclusively as a one-off timepiece for Middle Eastern nobility in 1982, the watch has a manual wind skeleton movement with diamond set hands. In addition, a double row of diamonds flank the bezel, and it is complimented by a diamond covered graduated double flat curb link bracelet strap. The diamonds were sourced from Michalis, a company established in 1963 and known for their high quality workmanship. The watch is stamped Corum Swiss 750 and is approximately 19.5cm long, with an approximate 3.5cm diameter.

Established in 1955 Corum are recognised for the aesthetic appeal and technical excellence of their high-quality wristwatches, made for some of the world’s most notable people. Although the current owner wishes to remain anonymous, their identity will be revealed to the successful buyer on completion of the sale. [Lot 54]

An Italian jewellery and luxury goods brand established in 1905, the company's Swiss subsidiary, Bulgari Haute Horlogerie SA, is responsible for Bulgari watch production.
