Patek Philippe Annual Calendar Chronograph 5960/1A-010

Patek Philippe Annual Calendar Chronograph reference 5960/1A-010 is a highly coveted luxury timepiece featuring a 40.5mm stainless steel case and an integrated, multi-link stainless steel bracelet with a polished finish. This rare "Ebony" variant stands out with its matte black opaline dial, framed by a silver-toned minutes and seconds track and accented by vibrant red hands for the chronograph functions. The dial neatly arranges complex horological functions: three arched apertures along the top edge display the day, date, and month of the annual calendar, a power-reserve indicator sits just under the 12 o'clock position, and a prominent "monocounter" sub-dial at 6 o'clock consolidates both the 60-minute and 12-hour elapsed chronograph. Underneath the dial beats the in-house, automatic-winding Caliber CH 28-520 IRM QA 24H, visible through a sapphire crystal caseback, which incorporates a column wheel and vertical clutch system that allows the flyback chronograph central hand to run continuously as a running seconds indicator.
