The Congreve clock is a luxury timepiece handcrafted in England. The rhodium-plated movement sits on a gloss lacquered carbon fiber base with a crystal glass mitred canopy. The Congreve, or Rolling Ball Clock, is named after its inventor Sir William Congreve (1772-1828) and is a favourite of clock collectors. The original clock was presented to the Prince of Wales in 1808 and is part of the Royal Collection at Buckingham Palace. Congreve was a prolific inventor famous for making the first solid fuel rockets at the Royal Arsenal in Woolwich in 1805 and subsequently used during the Napoleonic wars. It has been suggested that his clock was created for military purposes and the first "ball" used to trip the escapement was a musket ball.

The Navigator clock is a luxury timepiece handcrafted in England. The gold-plated movement sits on a walnut base with a crystal glass mitred canopy. The Navigator is a tribute to clockmaker John Harrison (1693 - 1776) who made the world's first marine chronometer. His unique timepieces made it possible for the first time for British naval officers to accurately calculate their longitude position. This technical breakthrough gave an extraordinary advantage to the navies of Great Britain in their quest for global exploration, trade and Empire. The rhythmic movement of the pendulum balances brings the Navigator to life.
