A Limited Edition honouring limitless courage
Making marine chronometers, we have a keen spirit of adventure. Respecting our heritage, we have a strong sense of history. The Shackleton Epic unites these themes.
The Shackleton Epic marine chronometer pays homage to Sir Ernest Shackleton’s intrepid 1916 crossing of Antarctica and its 2013 re- enactment. On both voyages, the crew depended on a Thomas Mercer chronometer to determine longitude. Limited to just 25, the Shackleton Epic acts as a timely reminder of the mariner’s perseverance in treacherous conditions. Designed and manufactured with painstaking care, it is a fitting tribute.
The chronometer case has an asymmetrical stainless steel body featuring precious elements in high-gloss Ziricote hardwood inlaid with fine metal settings. Inside, a gimbals suspension keeps the movement on an even keel in the roughest seas. Reflecting its inspiration, a map of the Southern Ocean showing the route of Shackleton’s voyage and the recent re-enactment is depicted on the rhodium-plated dial of the chronometer.
The main timber is Ziricote 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

A RE-ENACTMENT OF A HEROIC, HAZARDOUS JOURNEY
The 2013 voyage followed the route taken by Shackleton and his five companions as they sought help for the stranded crew of HMS Endurance, crushed by Antarctic pack ice. Retracing the 1916 journey, renowned adventurer Tim Jarvis and his five-man crew sailed an exact replica of Shackelton’s 22.5ft whaler, taking period clothing, food and navigational equipment. Like heroic Sir Ernest, he took a Thomas Mercer chronometer.
