Brand New IWC Portuguese 7-Day Power Reserve 1. Case: While maintaining the same

Brand New IWC Portuguese 7-Day Power Reserve 1. Case: While maintaining the same 42.4mm diameter, the new Portuguese 7-Day Power Reserve successfully reduced its thickness from 14.1mm to 13mm. 2. Crystal: To achieve a thinner profile, IWC adopted a domed sapphire crystal, which not only provides more space for the hands but also greatly enhances its aesthetics. Furthermore, the case back also features a domed sapphire crystal, allowing for a more unobstructed view of the beauty. 3. Dial: The dial has undergone significant changes compared to the old model. The new model eliminates the railway-style markers for the small seconds sub-dial at 9 o'clock. Simultaneously, the "1" area of the power reserve indicator at 3 o'clock no longer uses red. These adjustments and optimizations make the watch appear simpler and more refined, while highlighting the overall unity of the dial.
