1950s IWC Schaffhausen Ingenieur 666 AD “black granite”

The IWC Ingenieur 666 is a very underrated watch. Cousin of the Rolex Milgauss, for its magntic field protective case, it’s one of the first toolwatches produced, in the mid 50s. The AD version features a date indicator and dauphine hands.

This one is in excellent condition, its dial showing a nice granite patina, making it even more noticeable. An elegant choice, for true vintage lovers.
