The original spirit of DERRICK TOURBILLON, redolent of the world of oil, remains intact. The watch's entire movement represents the drilling process. A drive shaft sits on the right of the dial, between 2 and 4 o'clock. This powers a long articulated arm, known as the walking beam, between 10 and 2 o'clock. At its left-hand end is the oblong-shaped 'head', the most striking visual characteristic of a derrick.
The circuit naturally ends with a barrel at 9 o'clock, made from titanium and symbolising successful extraction. lt too is in constant rotation: Louis Moinet has dedicated it to marking the seconds, read off at the bottom of the barrel, on a red engraved seconds track. The rotating barrel is also engraved with Louis Moinet's name, atop its iconic Fleur de Lys motif.
