A ONE-OFF CHRONOMETER FOR A UNIQUE EXPEDITION
A 6-WEEK SAILING AND MOUNTAINEERING EXPEDITION TESTING SEAMEN’S TEAM DYNAMICS AND PERFORMANCE IS ALSO A TESTING TIME FOR A SPECIALLY BUILT THOMAS MERCER CHRONOMETER.
We have supplied a chronometer to the RN and RM Antarctic Endurance 2016, a research programme designed to analyse adventure-training techniques. The chronometer benefits from lessons learned when our founder tested his prototype shockproof suspension in Icelandic water. His experience led to the ‘Trawler Suspension’ fitted to this model.
The Antarctic Endurance chronometer’s design draws on our heritage to reintroduce the distinctive ‘Trawler Suspension’, a solution that withstands the violent motion of fishing vessels. In 1910, Frank Mercer took a trip on an Icelandic trawler to experience first-hand the conditions a chronometer suffered in rough seas. After three weeks of testing in different positions and conditions, he designed a new suspension with a shock-absorbing device using a frame supporting the gimbals by means of a set of springs and handles.
The main timber is Smoked Eucalyptus and the case is AISI 316 stainless steel..
The metal is hand-brushed 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 SIGNATURE PIECE
The Antarctic Endurance is equipped with the quintessential marine chronometer mechanisms calibre TM0801. This shines in its full beauty on the polished mirror plate of the base which not only reflects the intricacies of the movement, but also feature the engraved Antarctic Endurance logo and the motto “Inspire-Educate- Celebrate”.
