The caliber 558 SQ2 manual winding movement of this Breguet Classique Grande Complication watch features a decent 50-hour autonomy, 25 Jewels, and an eye catching tourbillon-in-a-cage complication with small seconds at 6 o'clock. The other functions that are displayed on the watch's silver dial are hours and minutes which are shown using an off-centered subdial at 12 o'clock. The case is made from precious 18K rose gold and is contained inside a smooth, round bezel. The strap is hand-sewn crocodile leather with a deployment buckle.
