2024 IWC Watch - IWC Portugieser Hand-Wound Tourbillon Day And Night IW545901

One of the highlights of the IWC Portugieser Hand-Wound Tourbillon Day And Night IW545901 watch is the flying minute tourbillon displayed at 6 o'clock on the dial. You must know that the flying tourbillon is the most complex item in advanced watchmaking technology. Before this, only experienced watchmakers could handle this task. The flying tourbillon equipped with this IWC watch places the balance wheel, fork lever and escapement wheel in a small frame, which rotates around its own axis once every minute. This continuous rotation reduces the impact of gravity on the oscillation system and improves the accuracy of the watch.

The mechanism consists of 56 parts and the total weight is only 0.675 grams. In order to ensure that the watch is as light as possible, the pallet fork and escapement wheel of this component are made of silicon and treated with DiamondShell® technology. This technical treatment can effectively reduce component friction and prevent energy loss, thus enabling a high power reserve of 84 hours. Thanks to the tourbillon stopping device, the device can stop completely to ensure that the wearer can set the time accurately to the second.

The innovative day and night display function simulates the eternal cycle of day and night by setting a small but eye-catching sphere on the dial. The day and night display of the sphere can be admired from both the dial proof and the movement side. Through the transparent sapphire glass case back, you can admire the IWC-made 81925 movement and its gold-plated components.

The small planet corresponding to the 9 o'clock position on the dial has two sides, light and dark, and rotates around its axis every 24 hours. It presents a fascinating visual effect whether it is day or night. This design was inspired by the whimsical ideas of IWC watchmaking apprentice Loris Spitzer. The day and night display system was integrated into the newly developed IWC self-made 81925 movement. Since the movement is hand-wound and has no oscillating weight, the rotating little planet can be seen from both the front and the back of the watch. The gold-plated flat surface is partially hollowed out, allowing you to admire the delicate structure of the barrel and other components. The watch is equipped with a polished and frosted 18K Armor Gold® hard gold case. Compared with traditional 5N red gold, this material has significantly higher hardness and is more wear-resistant. In addition, this watch is equipped with a black Santoni alligator leather curved strap, which brings a more comfortable wearing experience to the wearer.
