This masterpiece is an example of supreme skill and craftsmanship, not only with a view to the technical aspects but also the excellently executed work of the goldsmith and jeweller.

It is perfect for travelling because a concealed hinge in the bow can be used as a stand for the watch, so that it serves as a table clock. It is most likely a custom made piece for His Royal Highness Pengiran Digadong Sahibul Mal Pengiran Muda Sharif Jefri Bolkiah ibni Al-Marhum Sultan Haji Omar Ali Saifuddien Saadul Khairi Waddien, the brother of the Sultan of Brunei, born on November 6, 1954.

Prince Jefri Bolkiah is known for his extravagant lifestyle. His personal holdings included a huge art collection, the British jeweller Asprey, the New York Palace Hotel, Hotel Bel-Air in Los Angeles and Plaza Athénée in Paris. He is married to three wives, divorced from two others and has 18 children.
