Neuchâtel, September 2023 - 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).
