Blancpain Villeret Ultra Slim commissioned by Asprey to celebrate the 20 year reign of HM Sultan Qaboos bin Said of Oman. Sultan Qaboos was a renowned connoisseur of watches. The pieces that he commissioned are now some of the most rare and sought after watches in the world. This extremely rare Blancpain is believed to be part of a collection of only 20 pieces made, all individually numbered and branded Asprey on the case & strap. The exhibition caseback displays the fine Frederic Piguet cal. 21 base manual wind movement signed Blancpain. The original dial features the Royal Omani Khanjar Crest and the number 20 in Eastern-Arabic numerals. The watch remains in excellent original unpolished condition and appears to have been rarely worn from new.
