IWC Da Vinci Perpetual Calendar Ref. IW3750: A Horological Masterpiece in Yellow Gold

IWC Schaffhausen is renowned for its precision engineering and timeless designs, creating luxury timepieces that blend technical mastery with functional beauty. Established in 1868, the brand has become a leader in crafting complications such as perpetual calendars, chronographs, and moon phase displays. IWC’s commitment to innovation and craftsmanship is evident in its iconic Da Vinci collection, which showcases the brand’s expertise in advanced horology.

The Da Vinci Perpetual Calendar Ref. IW3750 is a landmark model in the collection, introduced in the 1980s as one of the first perpetual calendars powered by an automatic movement with a full four-digit year display. Designed by legendary watchmaker Kurt Klaus, it features a highly intuitive calendar system that adjusts for leap years and requires no manual correction until 2100. Encased in yellow gold and paired with a white tritium dial, this reference is a stunning example of IWC’s ability to combine technical innovation with classic design, making it a prized piece among collectors and enthusiasts alike.

Key Details To Consider

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 unpolished 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 serviced several years ago and has seen minimal use since. It performs reliably, running within -4/+4 seconds per day with an amplitude of approximately 230. 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.
