The Chapter 4.7 Onyx Tourbillon C. Lémanic by BA111OD is back in style and decked out in black for the festive season. In an elegant and refined style, this new model in the iconic collection features for the first time a deep black onyx stone dial revealing the tourbillon at 7 o'clock. The cut-out dial with its mirror-film back and transparent caseback reveal a skeletonised hand-wound mechanical movement housed in a 40 mm-diameter steel case with, as always, the crown at 4 o'clock. The whole is perfected by a black leather strap (fitted with two NFC chips). (Available now for pre-order on the brand's website or via the afluendors boutiques, this new Chapter will be delivered before Xmas 2023).

An elegant model

Distinguished from its predecessors by its refined, streamlined aesthetic, the Chapter 4.7 Onyx Tourbillon C. Lémanic was born of recurring market demand, amplified by the launch this summer of the Chapter 4.6 GMT Tourbillon 1920 Limited Edition (virtually sold out). It also echoes a growing trend towards a certain rediscovered classicism. A timeless, elegant timepiece that, thanks to its 40mm diameter, will suit everyone. Thomas Baillod, the brand's founder, explains: "The covid period had cut us off a little from elegance. Many designers are reintroducing classics, and that's what we've done with BA111OD, by completing the existing line". Conceived by the brand's senior designer, Liliane Murenzi, the Chapter 4.7 Onyx Tourbillon C. Lémanic is an aesthetic and technical feat of apparent simplicity.

A modern design

This new model may be classic in its design, but it is certainly modern in its conception: it has a 40mm steel case, with the crown still positioned at 4 o'clock. The dial is in deep black onyx stone, with a cut-out at 7 o'clock to reveal the tourbillon. The skeletonised hand-wound mechanical movement that drives it, with a 105-hour power reserve, was developed by the brilliant watch designer Olivier Mory, and has a caseback that allows its details to be admired. The back of the dial even has a mirror film to reflect the upper face of the movement.
