Chronometer P8 « with detent escapement » represents the first time that a detent escapement has been used in a wristwatch – offering a major improvement into precision.

This new invention is the result of many years’ development work and a constant research and committment. The long-held wish for a true UJS movement, with strong emphasis on precision, reliability and long intervals between servicing, has been addressed since 2003.

In the 19th century, Urban Jürgensen & Sønner was the official chronometer maker to the Danish Royal Household and to the Admiralty. The quality of the marine chronometers from the house of Jürgensen is still legendary among the collectors.

The caliber with detent escapement has undergone a thorough testing phase at the laboratories of Chronofiable SA and the C.O.S.C. who demonstrated results 40% higher than establishes brands.

In the past 25 years, in addition to individual, often complicated unique watches, the brand Urban Jürgensen & Sønner created wristwatches in small series from 50 up to a maximum of 300 examples. These watches were mainly based on ébauche movements from Frédéric Piguet, Le Brassus.

In order to close the loop from the past to modern times in an elegant and meaningful manner, development of a new movement and the chronometer escapement, suitable for use in a wristwatch, was undertaken. A particular problem was to ensure the necessary shockproof characteristics of the escapement. Having achieved this, the invention has been patented on a world-wide basis by Urban Jürgensen.

The Reference P8 is cased in either platinum, pink or yellow gold and is following the typical company tradition of a hand engine-turned silver dial, displaying hours, minutes, seconds and power reserve. The seconds are displayed on a small dial at “6”.
