We call IWC the "high-end watch engineer." Classical style, exquisite and elegant design, extremely simple to operate. Starting in 1868, every watch made by IWC was recorded in the watch factory's record book, and important parts were stored in high cabinets so that IWC watchmakers could thoroughly inspect the oldest watch movements. Therefore, each national watch can be regarded as a family heirloom for future generations.

This new chronograph watch from the Portuguese IWC watch family is a brother model of the 3714 model. It is 2 mm thicker than the 3714 watch. Although the latter is not easy to detect due to its arched watch mirror, the latter is not easy to detect due to its arched bracelet. The traditional watch mirror design looks more harmonious with the use of a rail-type minute ring. The rail-type minute ring has already appeared in the first batch of Portuguese watches, making the appearance of this series more harmonious.
The classic Portuguese chronograph watch is equipped with IWC's own 89361 battery cell, which is specially designed to measure longer chronograph time. The chronograph time can be up to 12 hours, 38 gems, vibration frequency of 28,800 times per hour, and 68 hours of power reserve. On the small dial at 12 o'clock, the chronograph record is displayed in time for easy reading. The 3904 model is available in 18K red gold or stainless steel, each with a silver-plated or dark sunburst dial and water resistance of 30 meters. Through the transparent sapphire crystal glass back, you can see the oscillating weight decorated with Geneva stripes. All styles of Santoni come with a crocodile leather bracelet.
The "senior watch engineer" of the IWC watch factory specializes in men's watches. Elegant style, exquisite design, exquisite craftsmanship and extremely simple operation - this is a watch that is famous all over the world.
All watches are well made, but like other good chronograph tools, require regular inspection and maintenance. To enable you to use it better, please send the watch to the official IWC after-sales service department every two years so that you can use it better and extend the service life of the watch.
