IWC Ingenieur Big Ingenieur Black

Reference IW5005-05

About this watch

The IWC Big Ingenieur Black IW5005-05 is a masterpiece of watchmaking that showcases IWC's commitment to craftsmanship and precision. Its bold and robust case is crafted from high-quality stainless steel, ensuring durability while adding a touch of elegance. The black dial is the true star of the show, providing a striking contrast against the silver stick indexes and hands. Protected by a sapphire crystal, the dial is resistant to scratches and provides excellent visibility. At the heart of this watch is the IWC caliber 51113 movement, an automatic movement that features 42 jewels and a power reserve of 168 hours. This movement is designed for reliability and longevity, ensuring precision timekeeping with a frequency of 21,600 vibrations per hour. The Big Ingenieur Black also features a date function and a power reserve indicator, adding to its functionality and making it perfect for daily wear. Its impressive water resistance of up to 120 meters makes it suitable for swimming or wearing in the rain without worrying about damaging the movement. With a height of 15.00 mm, this watch has a substantial presence on the wrist, but the carefully designed lugs allow for a comfortable fit, making it perfect for formal events as well as casual outings.
