Its biggest highlight design is that after the turbine tourbillon, IWC once again adopted the apprentice's innovative ideas and made the day and night display function three-dimensional. A small planet with light and dark sides is placed at 9 o'clock on the dial. It rotates once every 24 hours, simulating the cycle of day and night, echoing the concept of eternal watchmaking created by engineering. From the actual operation effect, I think when the black side of the sphere at night slowly moves to the gold color representing the day with the sunrise time, this touch of gold really brightens the highly polished obsidian black dial, echoing the gold flying tourbillon cage and the 42.4 mm 18K Armor Gold® hard gold case. The flying tourbillon at 6 o'clock on the watch can be seen through it.
The IWC 81925 self-produced movement uses a highly hollowed-out silicon escapement wheel and pallet fork. Although the silicon balance spring is crucial to the anti-magnetic performance of the watch, IWC also uses DiamondShell® technology similar to diamond silicon crystals on the silicon fork and silicon wheel to make the surface of silicon parts smoother, which can effectively reduce component friction and prevent energy loss, so as to achieve a high power reserve of 84 hours for the watch.
