IWC Ingenieur Mecaquartz Chronograph Alarm Yellow Gold / Black / Strap

About this watch

The IWC Ingenieur IW3815-06 is a luxury timepiece that combines precision engineering with exquisite design. At the core of this standout model is the Jaeger-LeCoultre caliber 633, a remarkable Meca-quartz movement that provides an exceptional user experience. This unique blend of quartz precision and mechanical finesse supports various functions like date display and chronograph, making it versatile for everyday wear. The yellow gold case exudes luxury and opulence, with a diameter of 34 mm and a height of just 9 mm striking the perfect balance between presence and wearability. Protected by a sapphire crystal, the dial is both scratch-resistant and stunningly clear, showcasing the beautiful black face adorned with Arabic numerals and stick hands. The closed back adds an element of mystery to the watch, keeping its inner workings hidden from sight. With a water resistance of 30 meters, the IWC Ingenieur can handle splashes and brief immersion in water, offering peace of mind for day-to-day wear.
