This IWC Automatic Ref. 109 is a truly exceptional example of 1960s Swiss watchmaking, crafted in solid 18K yellow gold (0.750) and powered by the legendary Caliber 8531 with Pellaton winding system. Manufactured in 1965, this piece exudes both refined elegance and technical excellence. The unblemished silver sunburst dial, sharply faceted gold indices, and baton hands capture IWC’s timeless design philosophy. The case retains beautiful definition and bold hallmarks, underscoring its near-mint condition—remarkably rare for a vintage IWC of this era. The robust movement, running strongly at 19–22 seconds per day with excellent amplitude, affirms IWC’s enduring reputation for precision engineering. Rarely do watches of this caliber, originality, and preservation surface for collectors—making this a centerpiece of any distinguished collection.

Dial and Hands  
The original silver sunburst dial is preserved in superb condition, showing clear IWC Schaffhausen signature and pristine printing throughout. Gold applied indices, sharply angled and mirror-polished, along with matching baton hands and a slim gold central seconds hand, accentuate the dial’s refined aesthetic. The framed date window at 3 o’clock sits crisp and unmarred.

Case and Crystal  
The solid 18K yellow gold case exhibits defined, unpolished lines and sharp lugs, with all hallmarks clear and prominent. The case profile remains true to factory form, with minimal wear and no significant blemishes. The domed acrylic crystal is clear, distortion-free, and free of notable scratches.

Inside beats the IWC Caliber 8531 automatic movement (movement serial 1701883), featuring the revered Pellaton winding system. The movement is running healthily, performing within 19–22 seconds per day with strong amplitude—hallmark traits of the Cal. 8531’s durability and reliability.
