IWC Automatic Date Pelaton Calibre 8531 18k Yellow Gold 1960s

IWC Automatic Date Calibre 8531 (18K Yellow Gold) – A Glorious Tribute to Mid-Century Horological Innovation

A triumph of precision engineering wrapped in timeless elegance, this IWC Automatic Date houses the legendary Calibre 8531—one of the most celebrated automatic movements of the 20th century. Hailing from an era when IWC (International Watch Company Schaffhausen) cemented its reputation for mechanical excellence and restrained sophistication, this piece exemplifies the brand’s enduring motto: Probus Scafusia—“Good, solid craftsmanship from Schaffhausen.”

Golden Weight & Craftsmanship – Solid 18K Case with Powerful Presence

Encased in remarkably heavy 18K yellow gold, this IWC is as much a tactile experience as a visual one. The solid gold case retains its original, unpolished contours, with sharp and deeply impressed hallmarks still proudly visible—a rare preservation of authenticity and material integrity. The case’s commanding presence is elegantly balanced by classic mid-century proportions, offering a perfect wrist feel for those who appreciate the weight and warmth of precious metal.

Its strong case lines and original finishing reflect IWC’s understated design language of the era: refined, purposeful, and beautifully proportioned. This is not merely a dress watch, but a statement of enduring value and horological gravitas.

A Movement to Marvel – The Ingenious Pellaton Calibre 8531

Powering this masterpiece is the IWC Calibre 8531, a self-winding marvel developed under the guidance of Albert Pellaton. This movement features IWC’s innovative Pellaton winding system, lauded for its efficiency, robustness, and technical elegance. It remains a cornerstone of IWC’s movement engineering legacy.

Fully serviced by our expert watchmaker, the calibre runs with excellent precision and is backed by a 1-year mechanical warranty, ensuring peace of mind for the next custodian of this horological treasure.

Elegant Original Dial & Luxurious Modern Strap

The stunning original dial has aged gracefully, with only minor natural marks adding to its vintage allure. Its classic silver tone and understated hour markers reflect the tasteful restraint of IWC’s golden-era design—nothing superfluous, just pure function and elegance.

Paired with a brand-new hand-made leather strap, crafted in Belgium from premium crocodile leather, this watch wears with both modern comfort and old-world dignity. The combination of vintage case and contemporary strap brings together the best of two worlds.
