IWC 1818 C.89

The IWC reference 1818 stands as a testament to the brand’s dedication to crafting high-quality, elegant timepieces during the 1970s. Powered by the iconic Caliber 89 movement, this model reflects IWC’s reputation for precision and durability. The reference 1818 features a stainless steel case measuring approximately 35mm in diameter, a size that was popular in its era and remains versatile for modern collectors. While some sources indicate this reference may feature a silver sunburst dial with Roman numerals, this variant showcases a champagne tone dial with non-numeral indexes, suggesting possible dial variations within the model. The understated yet sophisticated design, combined with the robust Caliber 89, makes the reference 1818 a sought-after piece among vintage watch enthusiasts, embodying a perfect balance of form and function.

The IWC Caliber 89 is a legendary movement, widely regarded as one of the finest manual wind calibers of the 20th century. Introduced in 1946 by Albert Pellaton, IWC’s technical director, it was designed to meet stringent military and civilian standards. This 17-jewel movement operates at 18,000 beats per hour and offers a power reserve of approximately 44 hours. Featuring a central seconds hand and, in some versions, a hacking seconds function for precise time setting, the Caliber 89 powered a diverse range of IWC watches, from the Mark XI pilot’s watch to elegant dress models like the reference 1818. Its production spanned over three decades until 1979, with later versions possibly incorporating 19 jewels for enhanced shock protection. The movement’s robust construction, meticulous finishing, and enduring reliability have earned it high praise from watchmakers and collectors, cementing its status as a horological icon.
