Description:
A watch that took five years to develop is finally presented, coming from IWC workshops and ensuring that this watchmaking company stays at the very top of haute horlogerie. This timepiece comes with a round-shaped case in stainless steel and it’s secured on the wrist with a black alligator leather strap and a stainless steel deployment clasp. The silver-plated dial features a number of highly useful functions; apart from the standard central hours and minutes, there’s also small seconds counter at nine o’clock, power reserve indicator at three o’clock and the aforementioned annual calendar at 12 o’clock showing month, date and day in three separate, semi-circular windows. The watch is powered by IWC-manufactured automatic 52850 caliber beating at a frequency of 28,800 vibrations per hour, with an outstanding power reserve of seven days. The case, featuring transparent, sapphire crystal back, is water resistant to approximately 30 meters.
