It's not every day you see a Reference 5905 in stainless steel but today that all changed with the new 5905/1A. The self-winding flyback chronograph with Annual Calendar features a 41mm case that surrounds a "sunburst" olive green dial and an integrated bracelet with polished and satin finishing. The watch is powered by Patek's Caliber CH 28-520 QA 24H, which features a flyback chronograph, a central chronograph hand, a 60-minute counter, annual calendar, and day, date, month, and day/night indications.
