B2704 Produced by ZF, a brand-new World Portugal 7-day chain

1️⃣ Case: With the watch diameter remaining unchanged at 42.4 mm, the thickness has been successfully reduced from 14.1 mm to 13 mm. 2️⃣ Mirror: To achieve a thinner appearance, iwc uses a sapphire mirror with a “pot lid” design. This not only provides more space for the hands to move, but also enhances the aesthetic appeal significantly. The mirror on the back of the watch is also a sapphire mirror with a “pot lid” design, allowing the back view to be displayed clearly and beautifully. 3️⃣ Dial: Significant changes have been made compared to previous models. The new dial eliminates the track-type markings for the 9 marks on the small second-hand dial. Additionally, the “1” area on the power reserve display for the 3 marks no longer uses red color. These adjustments and optimizations make the watch look more simple and refined, while also enhancing the overall consistency of the dial design.
