This 45mm monster from Zenith is the new El Primero caliber 4005C Tourbillion Concept chronograph watch. It has 35 jewels, beating at 36,000 bph and with a power reserve of 50 hours. The rotor is done in 22kt gold. The watches has the hour and minutes in the center, date indication positioned around the carriage of the tourbillon positioned at 11 o'clock. THere is a center seconds-hand with 30-minute counter at 3 o'clock and 12-hour counter at 6 o'clock. The case and push bottons are white gold and the hands and indices are 18K black gold. It's gorgeous but there is something about the design that seems off to me. Maybe it's all that unused real estate on the left side of the watch.
