About this watch

The IWC IW3731-05 Portofino Chronograph MecaQuartz is a stunning timepiece that beautifully blends tradition with modern technology. Its elegant design, innovative movement, and practical features make it a remarkable example of what IWC has to offer. The watch's sleek stainless steel case glimmers under light, while the white dial offers perfect contrast for readability. The rounded shape and minimalist aesthetic make it a versatile accessory suitable for both formal and casual occasions. At its core lies the remarkable Jaeger-LeCoultre caliber 631, often referred to as the 'MecaQuartz.' This movement combines quartz accuracy with mechanical chronograph functionality, resulting in impeccable precision. With functions for hours, minutes, small seconds, and a date display, this watch is more than just a pretty face. The chronograph allows you to time events with ease, making it practical for everyday use. The watch features stick hands that glide smoothly over the dial, providing a classic look that matches its overall aesthetic. A high-quality calf leather strap complements the watch's elegance while ensuring a comfortable fit. With a water resistance rating of 30 meters, this watch is suitable for daily wear but not designed for diving adventures.
