About this watch

The IWC IW3724-04 Portofino Chronograph MecaQuartz is a stunning luxury watch that beautifully marries elegance and functionality. This timepiece embodies the essence of the Portofino collection, inspired by the charm of the Italian Riviera. The sleek stainless steel build and refined black dial of the IW3724-04 make it a versatile accessory for any occasion. At its heart lies the Jaeger-LeCoultre caliber 631, a marvel of engineering that combines the precision of quartz with the charm of mechanical chronographs. This hybrid movement is a testament to IWC's commitment to excellence and innovation. The watch features a clean and legible display on its black dial, complete with stick and dot indexes accompanied by slim stick hands. A small seconds sub-dial adds a touch of sophistication, while the chronograph counters are intuitively placed for ease of use. Covered with a sapphire crystal, this watch is designed to resist scratches and maintain clarity. The case itself measures 38.00 mm in diameter and only 8.60 mm in height, offering a slim profile that sits comfortably on the wrist. With a water resistance of 30 meters, the IW3724-04 is ideal for everyday wear. This watch is not just about looks; it has a lug width of 20.00 mm, allowing it to be paired with a variety of straps. The stainless steel bracelet feels sturdy yet lightweight, making it comfortable to wear all day. As a luxury watch, the IWC IW3724-04 comes with a price tag reflecting its quality and craftsmanship. However, this is an investment in fine craftsmanship, heritage, and technology that will be reflected in its resale value. Choosing IWC is about embracing a legacy, as the brand has been producing high-quality timepieces since 1868.
