It is adorned with applied baton hour markers and the applied "IWC" logo, along with the "International Watch Co. Schaffhausen" script which remains crisp and legible. The original baton-style hands are in very good condition, showing only minimal signs of aging consistent with the watch's vintage nature. The dial is clean and sophisticated, embodying the minimalist dress watch design language of the early 1970s. Case and Crystal The stainless steel case measures 34mm in diameter, a classic size for vintage dress watches that wears slightly larger due to the thin bezel and dial-forward design. The case remains in excellent condition with defined lugs and clean surfaces. The acrylic crystal is clear and free from distracting marks, ensuring excellent visibility of the dial. Movement Powering this timepiece is the highly regarded IWC Caliber 403, a manual-wind movement known for its durability and precision.

This watch is not just a timekeeper but a piece of history from one of Switzerland's most prestigious manufacturers, ready to be worn and admired. History Founded in 1868 by American watchmaker Florentine Ariosto Jones, the International Watch Company (IWC) set out to combine modern American production methods with Swiss craftsmanship. Located in Schaffhausen, away from the watchmaking hubs of western Switzerland, IWC developed a reputation for solid, high-precision engineering. The company is celebrated for its technical innovations and timeless designs, particularly in the realm of pilot's watches and elegant dress watches like the one offered here. / Second Vintage SKU: IWC-IXX-0003
