Black Gold Derrick: Where time and black gold both flow Louis Moinet's spectacular new-look Derrick revolutionises the worlds of oil and watchmaking once more, with openwork mechanical parts of the movement further enhancing the technology involved in its extraordinary mechanism. The piece boasts a skeleton movement, haute horlogerie finishings, a three-day power reserve, and an all-new seconds display. This technical assembly, with over 45 parts, is topped by a six-screw bezel, now one of Louis Moinet's stylistic hallmarks. The Black Gold Derrick comes in a strictly limited edition of 28 pieces.
