DB28
XP Tourbillon
In highlighting this design, which has become iconic over the years, De Bethune celebrates the DB28's 10th anniversary by introducing a set of three watches in 2020. All three timepieces, all true to the DNA of the DB28, are interpretations of the same theme, independent of each other yet linked by their history, the work that went into them, the brand cues they reflect. Each one a creation in its own right, yet all share a kinship, like siblings.
