New IWC Portuguese 7-Day Power Reserve 1. Case: The new Portuguese 7-Day Power R

New IWC Portuguese 7-Day Power Reserve DDD 1. Case: The new Portuguese 7-Day Power Reserve maintains the same 42.4mm diameter while successfully reducing the thickness from 14.1mm to 13mm. DDD 2. Crystal: To achieve a thinner profile, IWC uses a domed sapphire crystal, which not only provides more space for the hands but also significantly enhances its aesthetics. Furthermore, the crystal on the case back is also a domed sapphire crystal, allowing for a more unobstructed view of the beauty. DDD 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. DDD
