Steel IWC Portofino Chronograph 39 Automatic Watch IW391503

The history of IWC Portofino chronographs can be traced back to 1988. In that year, the first Portofino chronograph IW3731 equipped with Jaeger-LeCoultre 631 quartz movement came out. In the next nearly 20 years, Portofino Tofino chronographs have always been dominated by quartz movements. In 2007, the first Portofino chronograph IW3783 equipped with the 79320 mechanical chronograph movement came out. Its appearance is considered to be the beginning of the modern Portofino chronograph. It has a diameter of 41 mm, willow leaf-shaped hands, 6, 9 , 12 layout and dual calendar are its distinctive features, and thus established the overall style of modern Portofino chronographs.

In 2011, IWC once again optimized the appearance based on the IW3783 and launched the IW3910. The biggest change was to replace the rigid square timing buttons with more refined and appropriate cable pile-type buttons, followed by the case diameter. Expand it to 42 mm, and turn the two numbers 12 and 30 on the two counters into red, making them consistent with the red 60 scale on the third hand. Since then, this classic design has been passed down to this day.

In 2021, the new 39mm Portofino chronograph was born. Compared with the 42mm version, the 39mm diameter obviously looks more compact and delicate. The latest 6 and 12 layouts and the cancellation of the dual calendar also make the entire watch more compact and delicate. The dial looks more symmetrical and pure. The four willow-shaped hands on the dial are paired with a slender chronograph seconds hand, which creates a sense of relaxation for the entire watch. The 6 o'clock and 12 o'clock positions are combined by stick-shaped hour markers. The Roman numerals with the effect of being truncated by the small dial add infinite sophistication to the entire watch. In addition, the waterproof performance of the 39mm version has also increased from 30 meters to 50 meters in the 42mm version.
