BA111OD UNVEILS THE NEW CHAPTER 4 TOURBILLON T.V.D. POWERED BY ITS FIRST IN-HOUSE CALIBRE 

Nearly five years after presenting its first tourbillon, BA111OD unveils a new generation of the emblematic Chapter 4 Tourbillon T.V.D., more assertive, more refined and more accomplished in its expression. Faithful to the Maison’s codes, this evolution stands out through a reimagined architecture, an extended 120-hour power reserve and an openworked construction inspired by skeleton aesthetics, fully showcasing the mechanics.

Available in 39 mm and 43 mm, the model is distinguished by a redesigned 904L stainless steel case with a tantalum-grey DLC treatment. The interplay of volumes, the alternation of polished, sandblasted and vertically satin-finished surfaces, and the restraint of its lines all enhance the watch’s visual depth and overall character. More refined in its execution, the dial opening frames the tourbillon at 7 o’clock and offers a more direct view of the barrel, the central organ of the movement.
