IWC Portugieser Hand-Wound Tourbillon Day & Night Watch Review

The IWC Portugieser Hand-Wound Tourbillon Day & Night watch uses 18K Armor Gold® hard gold to create a 42.4 mm case, which is consistent with the size of the popular Portugieser. As a special red gold of IWC, hard gold has a more complicated production process. It is harder and more wear-resistant than traditional red gold. From the color point of view, this red gold is not only rich in color, but also more shiny after IWC polishes the side brushed front bezel lugs.

The dial used for the day and night display tourbillon is obsidian black, which is also the exclusive color of the 18K red gold case. It represents the city when night falls and the lights are on. Black gold is a classic color combination that will never go wrong. High-end luxury style is also synonymous with black gold. IWC uses a dial that has been treated with multiple layers of paint to exude a deeper luster. It is matched with a gold case and decorated with gold digital hour markers and hands to create a warm effect like the warm lights in the city night scene.

I think the most eye-catching design is the small planet at 9 o'clock on the dial. The idea comes from watchmaking apprentice Loris Spitzer, who simulated the cycle of day and night by rotating the spherical day and night display with light and dark sides once every 24 hours, which also echoed the concept of eternal watchmaking created by engineering. At the same time, from the actual operation effect, I think when the black side of the sphere at night slowly turns to the gold representing the daytime with the sunrise time, this gold really brightens the highly polished obsidian black dial, echoes the gold flying tourbillon cage, and the 42.4 mm 18K Armor Gold® hard gold case, achieving the ultimate balance in functionality and design aesthetics.

The tourbillon at 6 o'clock. If you look closely, you can see that the IWC 81925 movement uses a highly hollowed-out silicon escapement wheel and pallet fork. Although the silicon hairspring 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. It is worth mentioning that this year, IWC officially began to use silicon hairspring movements.
