Brand: IWC Serial Number: 1586152 Movement: Manual winding, Caliber 89 Dial: Creamy base with heavy stardust spotting, pervasive oxidation, and applied faceted indices Case Size: 35 mm Case Material: Stainless steel Production Year: 1960 Condition: Good vintage condition with prominent age-consistent dial patina Dial and Hands The dial features the classic "International Watch Co SCHAFFHAUSEN" signature printed in an elegant black serif script. It is adorned with applied, faceted baton hour markers, highlighted by a prominent double-baton index at the twelve o'clock position. The outer minute track is composed of precisely recessed dot markers. In terms of condition, the dial exhibits heavy, pervasive stardust spotting and oxidation across the entire surface. This extensive aging has transformed the original light finish into a highly textured, freckled canvas, providing a deeply patinated vintage character while remaining entirely legible. The faceted dauphine hands and the elegant center sweep seconds hand show matching oxidation and surface aging, aligning perfectly with the dial's honest, unpolished aesthetic. Case and Crystal The 35 mm stainless steel case is distinguished by its beautifully sweeping, subtly downturned lugs that retain excellent thickness and strong geometric profiles. A smooth, steeply angled polished bezel frames the domed acrylic crystal, contrasting nicely with the brushed finish on the case flanks. The watch features a simple, finely fluted pull-push crown. The snap-on caseback is clean and structurally sound, with the inner caseback correctly stamped with the prestigious Probus Scafusia seal, the IWC maker's mark, and Staybrite steel designations alongside the serial number 1586152. The case displays normal, honest handling marks and light surface wear consistent with its age, but remains exceptionally well-preserved overall without any deep gouges or signs of over-polishing. Movement Powering this timepiece is the legendary IWC Caliber 89, a manual-winding, center-seconds movement celebrated for its robust architecture and refined finishing. The rhodium-plated movement is beautifully decorated with Geneva stripes and features polished screw heads and gold chatons. It is clearly stamped "INTERNATIONAL WATCH Co SWISS" along with the movement serial number 1558812. Performing well within expected vintage tolerances; running strong and steady. Timegrapher results show an accuracy of -20 to -25 seconds per day. Strap The watch is fitted with a heavily textured exotic leather strap featuring a distinct scale pattern and contrasting thick white stitching. This bold strap adds a substantial visual presence to the wrist and is secured by a classic stainless steel pin buckle. Condition This timepiece is presented in good vintage condition. The stainless steel case remains sharp and well-defined, showing only expected light wear from normal use. The dial is the defining feature of this watch, presenting heavy, distinct spotting and widespread oxidation that offers a deeply aged, unique aesthetic without any structural damage or print loss. The hands display matching patina. The movement is remarkably clean and functions beautifully, offering a strong contrast to the aged exterior. Dimensions Case Size: 35 mm Remarks A captivating example of mid-century IWC craftsmanship powered by one of the most respected manual-wind calibers ever produced. The pervasive, heavy dial patina ensures this piece is entirely unique, appealing directly to collectors who value distinct, honest vintage character over a pristine, restored appearance. It is a highly wearable piece of horological history. History Founded in 1868 by American watchmaker Florentine Ariosto Jones, the International Watch Company was established to marry American engineering precision with traditional Swiss craftsmanship. The mid-twentieth century represented a defining era for IWC, largely driven by the introduction of the Caliber 89 in 1946. Developed by the legendary technical director Albert Pellaton, this movement became the backbone of IWC's post-war production, celebrated globally for its incredible durability, elegant design, and chronometer-level potential. Watches from this period remain highly coveted by purists for their timeless proportions and uncompromising mechanical excellence. / Second Vintage SKU: IWC-ISX-0005
