Pre Ingenieur IWC automatic, ref. 648A, from 1963

The IWC ref. 648a cal. 8531 Pre-Ingenieur is a very rare and sought-after model from the 1960s, considered the model that launched IWC’s top-tier Ingenieur line and established its core design language. The watch stands out with its large 36.5mm jumbo case without a crown, featuring a narrow bezel that makes the dial appear larger. At the heart of the watch beats the legendary cal. 8531 automatic movement.

This movement is considered one of the best in history, renowned for its reliability and precision. The silver-colored dial with a sunburst finish is complemented by beautiful polished prism-style hour markers and meticulously crafted hands.
