LEGACY RATTRAPANTE
SPLIT-SECONDS RENAISSANCE

Drawing deep inspiration from its rich history, Edouard Koehn is reviving the split-seconds chronograph, an iconic complication that featured prominently in the brand’s legacy. The split-seconds chronograph or rattrapante chronograph has long been classified by connoisseurs as the most complicated among chronographs.

The genesis of the development of this new Legacy rattrapante model is the result of a close collaboration with 10Ten Labs, Edouard Koehn’s exclusive distributor in Bahrain and Saudi Arabia. “We are excited to be able to continue the dynamic development of our Edouard Koehn brand in partnership with Mr. Khaled Zainalabedin and the entire 10Ten Labs team” said Bernard Fleury, Edouard Koehn CEO of the family-owned Company.

The movement of the new Edouard Koehn Legacy Rattrapante was constructed such that it replicates the dial layout of the original pocket watch chronograph produced in the early 1900s. The raison d’être of the split-seconds chronograph is to simultaneously measure intermediate times, a function particularly sought-after in the dynamic world of sports. Master watchmaker Edouard Koehn (1839 to 1908) was recognised for his mastery of this high complication.

The instantaneous 60-minute chronograph counter is positioned at 12 o’clock while the small seconds is at 6 o’clock.

The red central chronograph seconds hand is activated by the pusher at 2 o’clock and Edouard Koehn movement engineers developed a coaxial arrangement with the pusher on the crown controlling the blue central split-seconds chronograph hand. The pusher at 4 o’clock resets the chronograph function.

Faithful to the historic model, the Legacy Rattrapante Split-seconds chronograph is enhanced by a grand feu enamel dial, a tribute to the mysterious technique of enamelling. Used by watchmakers since the 15th century, this craft has its roots in antiquity.

Dial enamelling consists of applying the meticulously prepared enamel powder onto the dial’s base plate and fusing the two together by cooking them at 840 degrees Centigrade / 1,544 degrees Fahrenheit.

The intense heat is due to the high melting point of the enamels and this explains why this type of enamelling is referred to as grand feu. It has been elevated to the level of an art, so much so that it requires manual precision and craftsmanship.
