In a new variation of the extraordinary UJS-P8 detent escapement, the first detent escapement ever created for a wristwatch, the choice was made to renew and connect with the history, tradition, experience and pursuit of accuracy at Urban Jürgensen & Sønner, a quest which has been at the heart of the brand’s existence since the 18th century.
 
The creation of the central seconds hand is a bit more complex than using an indirect second’s sub dial, has additional gears are needed to transfer power through the cannon pinion to the seconds hand from the movement. In fact you will immediately note the motion of the second’s hand which in this case jumps in increments of 1/3 second due to the nature of the detent escapement’s special construction. This same effect can also be noted in ship’s chronometers from the same period as the founding of Urban Jürgensen’s workshop.
