What Is the IW389410? The Design Story Behind the Le Petit Prince Edition
The IWC Pilot’s Watch Chronograph 41 Le Petit Prince, reference IW389410, is a new special edition introduced by IWC in 2026. Presented at Watches and Wonders Geneva 2026, it is the first Le Petit Prince edition of the Pilot’s Watch Chronograph 41 to feature a white ceramic case. The watch combines a white zirconium oxide ceramic case with a deep blue sunray-finished dial and gradient effect, while the titanium caseback is engraved with an image of the Little Prince.
IWC’s collaboration with the heirs of Antoine de Saint-Exupéry dates back to 2006. Since then, the brand has created a number of Le Petit Prince editions, with deep blue dials becoming one of the recognizable design elements of the series.
The IW389410 measures 41.9 mm in diameter and 15.5 mm in thickness. It is powered by IWC’s calibre 69381 automatic chronograph movement, offering a 46-hour power reserve. The watch also features a convex sapphire crystal with anti-reflective coating on both sides and 10 bar water resistance.

Is Protection Film Necessary for a White Ceramic IW389410?
This is one of the first questions that comes up when choosing IWC IW389410 protection film.
The answer is not simply yes or no. According to IWC, the white zirconium oxide ceramic used for the IW389410 is lightweight, hard and resistant to scratches, with a smooth and refined surface finish.
However, scratch resistance does not mean that a watch is completely immune to marks from everyday wear. Contact with desks, clothing, other objects and accessories can gradually affect exposed areas such as the case sides, lugs and connection points. On a watch whose design relies heavily on the contrast between white ceramic and deep blue, preserving the original surface condition can be particularly important.
The purpose of protective film is therefore not to compensate for any weakness in ceramic itself. Instead, it adds a replaceable external layer between the watch and everyday contact. For a special-edition watch, this can help reduce unnecessary surface marks while preserving the original appearance for longer.

Where Should IWC Pilot’s Watch Chronograph 41 Le Petit Prince Protection Film Be Applied?
For IWC Pilot’s Watch Chronograph 41 Le Petit Prince watch protection film, the key consideration is not simply how much of the watch is covered. More important is whether the film has been designed around the actual geometry of the IW389410.
Different parts of a watch have different curves, edges, bevels and connection structures. A model-specific protection solution can therefore be divided into individual sections rather than relying on a generic sheet of film.
For the IW389410, possible coverage positions include:
Glass — protection for the crystal area.
Case - Side — protection for the sides of the case, which can come into contact with surrounding objects during everyday wear.
Case - Back — protection for the external caseback area.
Lug*4 — protection for the four lugs.
Lug - Back*4 — protection for the rear surfaces of the four lugs.
Depending on the configuration, additional protection can also cover Clasp - Side and Clasp - Front.
This reference-specific approach is more suitable for a high-end mechanical watch than a universal film cut. The objective is not simply to cover the surface, but to ensure that the edges align correctly, curved areas remain properly fitted and the film does not become visually distracting during wear.

How to Choose IW389410 Protection Film: Thickness, Precision and Transparency Matter
When searching for IWC Pilot’s Watch Chronograph 41 Le Petit Prince IW389410 watch protection film, the most important factors are not simply whether the product is described as “TPU film.” The material characteristics and cutting accuracy are equally important.
A film that is too thick can become more noticeable after installation, while inaccurate cutting can lead to uneven edges, lifting or poor alignment with the watch’s geometry. For this reason, a model-specific cut is generally more appropriate than a universal-size protective film.
A protection solution designed for the IW389410 can use approximately 0.16 mm thickness, 0.01 mm cutting precision and 92.5% light transmission. A relatively thin film can reduce its visual presence, while precise cutting helps it follow the contours of the case, lugs and other detailed areas.
This is particularly relevant to the Glass area. The IW389410 uses a convex sapphire crystal with anti-reflective treatment on both sides. Therefore, when film is applied to the crystal, transparency and conformity to the curved surface should be considered alongside the overall coverage.

Will Protection Film Change the Original Appearance of the IW389410?
This is another practical concern, especially with a white ceramic watch.
The IW389410 combines a white ceramic case, deep blue sunray-finished dial and white rubber strap to create its distinctive visual identity. IWC itself highlights the contrast between the white ceramic and deep blue dial as an important part of the special edition’s design.
Ideally, protective film should provide protection without making the watch look as though an additional layer has been added. This is why film thickness, transparency and cutting accuracy need to be considered together.
For the case, the focus is on clean and natural edges. For the Glass, transparency and surface conformity are especially important. For areas such as Lug4, Lug - Back4 and Endlink, accurate cutting becomes even more important because of their more complex shapes and connections.
In other words, a well-designed watch protection film should not dominate the appearance of the watch. At normal viewing distance, the original material, proportions and overall design should remain as natural as possible.

The Most Important Factor in IW389410 Protection Film Is Precise Fit
The IW389410 is a highly integrated Pilot’s Watch that combines a white zirconium oxide ceramic case, deep blue gradient sunray dial, titanium caseback engraving and IWC’s calibre 69381 column-wheel chronograph movement.
For this reason, choosing protection film should be less about simply asking whether a film is available and more about considering three specific points.
First, is the film specifically cut for the IW389410?
Second, is the design based on individual areas such as Glass, Case - Side, Case - Back, Lug4, Lug - Back4 and Endlink?
Third, is the film thin and transparent enough, with sufficient cutting accuracy to follow the original geometry of the watch?
For a white ceramic Le Petit Prince edition, protection is ultimately not about changing the watch. It is about helping preserve the original design as the watch accumulates years of wear. The most useful protection is therefore based on precise fit, low visual presence and coverage designed around the actual wearing areas of the watch.
