Reference 270.2.73 was launched in 1994 in a limited edition of 500 pieces. The pink gold case is no coincidence, as this is considered the gold color which yields best acoustics thanks to the presence of copper in the alloy. The movement was designed in-house by watchmaker Eric Coudray and delivers remarkably clear sound, a true achievement given the limitations imposed by the case size and shape. Aesthetically, the piece is extremely understated, even the repeater slide is much less prominent than what usually found on chiming watches, a consequence of the reversible case design. On the dial, however, a whimsical concession is made, and the regulating organ is visible through a dial opening. Such a detail allows the repeater to truly come alive not only acoustically, but also visually. As a matter of fact, the regulating organ of a repeater is arguably the most "dynamic" feature to be found in a mechanical wristwatch after the balance wheel.
