The IWC Da Vinci Perpetual Calendar Ref. IW3750 in yellow gold is a remarkable example of sophisticated watchmaking. Recently acquired from its original owner, who cherished the piece for over two decades, this watch has been rarely worn and remains in outstanding, all-original condition. The yellow gold case exhibits visible but minimal signs of wear, a testament to its careful preservation. The original plexiglass crystal has been lightly polished, maintaining its clarity and character. The white tritium dial is in excellent condition, with all tritium plots intact and evenly aged to a warm yellow hue, perfectly matched by the original hands. What sets this piece apart is its completeness. Accompanied by all original boxes, papers, and documents, it includes the rare IWC watch winder. While the winder is currently non-functional, it is believed that replacing the adapter could restore its operation. According to the original owner, the winder was fully operational in the past. The movement was fully serviced early August 2025, all date functions synced, and running perfectly. The watch comes fitted with a newly crafted brown alligator strap and retains its original IWC yellow gold pin buckle. Dated to 2000, this full set IW3750 is an extraordinary find, blending mechanical complexity with a rich history, all while maintaining its original charm. A true collector’s piece, ready to enhance any distinguished collection. **Reference:** IW3750 **Size:** 39mm **Year:** 2000 📜 Includes: Original box, papers, IWC watch winder 💵 Price: $10,470 + FREE overnight shipping with FedEx fully insured.
