KTS factory IWC IW659801 top replica watch

Today, we are going to review an IWC replica watch produced by the KTS factory together with fellow watch enthusiasts. This watch features a uniquely customized day-night display movement, a 904L stainless steel case, and is set with 66 moissanite diamonds to match the authentic version. The highly restored pumpkin-shaped crown and the slender lugs, which are more in line with female ergonomics, will also be examined. This article will provide a detailed evaluation of whether these aspects meet everyone’s expectations.

This time, KTS Factory has launched two IWC watches with different colors, namely:
1. Silver dial taupe calfskin strap. Model: IW459801
2. Blue dial and blue calf leather strap. Model: IW659801

Exclusively Customized Day-Night Display Movement

This IWC replica watch is equipped with a KTS factory exclusive custom day-night movement. The movement has a frequency of 28,800 vibrations per hour, a power reserve of approximately 48 hours, and a daily timekeeping deviation controlled within ±10 seconds. The case back restores the original solid back design, which not only better ensures that it won’t be detected, but also provides improved water resistance. The subdial at the 6 o’clock position rotates according to the change between day and night, providing a genuine function. Moreover, the dial color is very realistic, making it excellent for both handling and viewing pleasure.

Quick-Release System

Many replica watches have small flaws, such as not being equipped with a quick-release system; they only restore the original strap. However, KTS factory has managed to restore IWC’s quick-release system in this watch. Restoring this detail can make the entire watch more appealing, because it allows one to easily change to a favorite strap at home for personal satisfaction. It can save a significant portion of costs, and the strap can be replaced at any time if it wears out or encounters problems.

Moissanite Diamond Bezel

The bezel of this IWC watch from KTS Factory uses moissanite to restore the texture of a genuine diamond, unlike ordinary rhinestones or synthetic diamonds. Moissanite more closely resembles the appearance of diamonds and has a very strong sparkle. The visual effect allows you to directly perceive its brilliance, and moissanite is also more cost-effective, making it more durable for everyday wear and less likely to be damaged by knocks.

Eileen Gu’s Signature Women’s Watch

This watch is the same model worn by the famous Olympic champion Eileen Gu. The dial features a smooth and natural blue sunburst pattern. Visually, it feels as if we change along with the sun, as if entering a world uniquely belonging to this mechanical watch. The diamonds on the markers are all hand-set, with classic Roman numerals paired with leaf-shaped hands. Although the dial looks very simple, it exists in harmony, complementing and matching perfectly, which is why Eileen Gu chose this model. If fans find the authentic version too expensive, they can opt for this KTS factory version, which offers better value for money.

Calfskin Strap with Butterfly Clasp

The IWC replica watch strap and clasp from KTS factory feature a butterfly folding clasp and calfskin strap. The calfskin is imported from Italy, carefully selected from top-grain leather, treated with vegetable tannins, giving it a soft texture and long-lasting durability. However, it is important to note that the strap requires professional daily care and regular maintenance. Its texture is soft and unique, making it a highly recommended watch, whether for personal use or as a gift. Additionally, this watch is one of the best value-for-money watches in 2026. The clasp is not an ordinary folding clasp but a butterfly style, which is more attractive and aligns with women’s preferences. It elevates the entire watch to a clever, delicate, and distinctive level.
