Introducing a new dial to the esteemed 5170 family, this stunning timepiece features a contrasting deep ebony black opaline dial with gold applied Breguet numerals. Along with the central chronograph hand, it also features small seconds at the nine o'clock position and a 30-minute elapsed time counter at the three o'clock position. Behind these functions is a manually wound CH 29-435 PS caliber vibrating at 28,800 v.p.h. and featuring a power reserve of 65 hours when the chronograph is disengaged. Incorporating 33 jewels and 269 parts, it is nested inside a 39.4mm white gold case and is visible through the sapphire-crystal case back. The watch is water resistant to 30m and worn on a shiny black alligator leather strap.
