The IWC Portugieser Squelette Mr. FA Jones, model number IW544206, is an exceptionally refined and artfully designed timepiece that pays homage to one of IWC's founding fathers, Florentine Ariosto Jones. This model is distinguished by its exquisite skeletonized finish, which reveals the intricate inner workings of the movement while maintaining the classic elegance of the Portugieser series. Design and aesthetics: Dial: The most striking feature of the watch is the fully skeletonized dial, which allows one to see the finely crafted movement in action. This type of design requires the utmost precision and craftsmanship to be not only functional but also aesthetically pleasing. The watch typically displays minimal additional detail so as not to distract attention from the movement, often using Roman numerals to mark the hours. Case: The case is made of 18-carat white gold or another precious metal and usually measures around 43 mm in diameter, which is typical for the Portugieser line. This generous case format provides ample space for the skeletonized dial and emphasizes the visual complexity of the movement. Technical features: Movement: At the heart of the watch is a manually wound IWC manufacture caliber, specially developed for this watch to offer both technical performance and aesthetic brilliance. Such calibers are often equipped with a power reserve of several days and demonstrate the high level of IWC's mechanical expertise. Water resistance: Due to their sophisticated and open design, skeleton watches are usually not highly waterproof. These models are usually only suitable for light everyday use and should be protected from water. Bracelet: The strap is typically made of high-quality leather, such as alligator leather, and features a pin buckle or a folding clasp made of the same noble material as the case. This adds to the luxurious and elegant character of the watch. A true masterpiece of watchmaking, the IWC Portugieser Squelette Mr. FA Jones IW544206 represents the marriage of artful engineering and historical tribute. It is ideal for collectors and watch enthusiasts who have a deep interest in the mechanics and history of watchmaking. We offer you a 1-year warranty.
