Produced during the post-war resurgence, this model embodies the values that shaped IWC into one of the most respected manufacturers of its time. Its design is a masterclass in classic Calatrava aesthetics: a clean, understated dial framed by a slim bezel and graceful bombe-style lugs that curve effortlessly into the wrist. The silvered surface giving depth and character to the applied markers and dauphine hands that catch the light with subtle charm. Every detail feels considered, deliberate, and unmistakably IWC. Inside beats the renowned Caliber 852—an early iteration of the groundbreaking Pellaton winding system introduced in 1952. This movement marked a turning point for IWC: efficient, robust, beautifully finished, and engineered with a level of practicality that made it a standout in mid-century automatic watchmaking. Variants of the Pellaton system remain at the core of IWC’s modern lineup, underscoring its lasting significance. Housed in a beautifully preserved case, this piece retains its crisp lines and original IWC fish-logo crown—small but desirable details collectors always look for. At approximately 36mm, it wears with timeless elegance, offering the perfect balance between vintage proportions and modern versatility. This example remains in great condition for its age, showing little scratches and no dents. The dial is clean and crisp, the crystal is clear, though you can see some patina spots here and there. It has been recently serviced and is keeping great time at +/-5s a day. The watch comes fitted on custom leather straps. Watch comes with standard watch box (no papers). Price: $1250 + $60 flat shipping fee (via UPS/DHL with tariffs and duty fee covered). Payment via PayPal F&F or G&S (+4.6% fee paid by the buyer). Not accepting trades.
