A UNIQUE PIECE CELEBRATING AN INDIVIDUAL RACE AGAINST TIME
MAKING MARINE CHRONOMETERS, WE ARE DEEPLY ENTRENCHED IN NAVIGATION. RESPECTING OUR HERITAGE, WE HAVE A STRONG SENSE OF HISTORY. THE ATLANTIC CHALLENGE UNITES THESE WORLDS.
The Atlantic Challenge marine chronometer pays homage to Sir Francis Chichester and its heroic speed record during this eponymous race. Setting off from Bissau in Portuguese Guinea on January 12th 1971, aboard his 57ft ketch Gipsy Moth V, Chichester was the first to break the barrier of 200 miles per day in single-handed sailing. Limited to one unique piece, the Atlantic Challenge is the heir of Thomas Mercer marine chronometer No 23543, the timekeeper used to calculate longitude during this unforgettable race against time. Designed and manufactured with painstaking care, it is a fitting tribute.
The chronometer shows an elegant combination of high-gloss Ziricote, White Ripple Sycamore and Oak, surrounding a fine hand-painted dial featuring the Atlantic Ocean map on which the plot course of the 1971 Atlantic Race is represented. As a crowning touch of incomparability, engraved on the base plate are Sir Francis’ signature and Gipsy Moth V’s silhouette and deckplan, the latter showing the position on board of chronometer No 23543.
The main timber is Ziricote, White Ripple Sycamore, Oak and the case is AISI 316 stainless steel..
The metal is hand-polished and the main timber is sheen lacquer, full grain finish and burnished..
The mechanism breaks new ground while retaining the classic elements of a pure marine chronometer. With a symmetrical layout and skeletonised plates, the detent escapement has been moved from its traditional place on the back plate to a new position where it can be viewed through the dial apertures. The gimbals suspension allows the mechanism to be rotated to reveal its innovative craftsmanship.Learn More

Sir Francis Chichester’s name is a legend in British navigation. Aviator and sailor, he was knighted in 1967 by Queen Elizabeth II as the first person to sail single-handed around the world by the clipper route, and the fastest circumnavigator. For the ceremony, Her Britannic Majesty used the sword employed by her predecessor Queen Elizabeth I to knight Sir Francis – Drake, the first Englishman to circle the globe. The new British passport features the Gipsy Moth IV alongside a modern marine chronometer and its ancestor H4, John Harrison’s invention that finally solved the problem of longitude determination at sea.
