IWC Portuguese Chronograph 41mm IW371446

This Portuguese represents a perfect mixture of highly suitability for daily wearing and the timeless elegance. The classic looking case with a fixed bezel measures near 41mm in diameter and 12.3mm in thickness, appropriate for both men and women. Traditionally, on the right side of the case, there is a screw-in crown and two chronograph push-buttons. The self-winding movement built on 31 jewels preserves 44 hours of power reserve when fully wound and oscillates at the rapid frequency of 28,800 vibrations per hour, and provides decent water-resistance up to 30 meters (100 feet) beneath water surface.
