This stainless steel self-winding automatic date model, manufactured by IWC in the 1960s, embodies a "Calatrava" design, a quintessential look from that era, that pairs exceptionally well with a tailored suit. The watch is in remarkable condition, showcasing several distinctive features that make it truly exceptional.

At the heart of the watch is the Caliber 8531, a groundbreaking automatic movement featuring the revolutionary Pellaton winding system. Introduced in 1950 and first mass-produced in 1952, this mechanism is renowned for its exceptional winding efficiency. The movement operates at 19,800 vibrations per hour, delivering impressive precision.

The watch's design is a study in refined details: a classic Calatrava-style dial adorned with elegant long dauphine hands, topped with an inner cyclops lens beneath the crystal. Unlike many vintage IWC watches that have been refinished, this timepiece boasts an original dial with a captivating "tropical" patina—a subtle transformation that collectors prize for its unique character and testament to the watch's authentic aging process.

The stainless steel case maintains its original integrity, featuring sharp, unpolished edges that preserve the watch's authentic character. A clean case back complements the case's crisp geometry. The drilled lugs are a particularly desirable feature, offering practical versatility by allowing easy strap changes, enabling the wearer to effortlessly adapt the watch's aesthetic to various styles and occasions.

Key Features:

  1. 35mm, sharp and unpolished case retaining the original shape and design
  2. Double indices at 12 hours with long, sharp dauphine hands
  3. Original Plexiglass with and cyclops lens
  4. Original unsigned crown
