IWC flieger chrono IW388101 41mm
New and unworn. Full set.
The new models come in a stainless steel case measuring 41mm in diameter and 14.5mm in height. Featuring the quick strap change system, compatible with the leather strap and metal bracelet options available with the models, the case sports sapphire crystals on both sides. The cases that are resistant to 100 meters of water pressure, which is quite sufficient for a sports chronograph, are accompanied by a screw-lock winding crown.
The model family is powered by the manufacture Caliber 69385. The movement, which includes day and date functions in addition to its automatic chronograph feature, operates at a frequency of 4Hz (28.800vph) and offers a power reserve of 46 hours when fully wound.
