During the 1970s, His Majesty Qaboos bin Said Al Said, the Sultan of Oman, commissioned many watch manufacturers to create custom order pieces, many of which displayed the "Qaboos" or a "Khanjar" symbol. While Rolex is best known for creating these custom pieces, the Sultan also tasked watchmakers like IWC, Baume & Mercier and Chopard to create watches bearing the royal symbol.

The present watch, retailed by Asprey, features the "Khanjar" symbol at 6 o'clock, which is very prominent and eye catching. In lieu of Baume & Mercier's signature is the Asprey logo, as the watch was distributed through the London retailer. The case is furthermore preserved in excellent condition, attesting to its previous owner's care and appreciation for the watch. All hallmarks, case and reference numbers are incredibly crisp to the case back, and the inside case back is stamped with Birmingham hallmarks for 1972. The watch retains its original Baume & Mercier crown.

The Sultan enjoyed a wide range of watches, and the present example gives a glimpse into his tastes and sensibilities.
