This is a super rare, IWC Ingenieur, reference 666. Diameter 36.5mm without crown. Steel. Automatic movement.
The Reference 666 Ingenieur was IWC’s first foray into producing a purpose-built anti-magnetic tool watch for scientific and industrial usage. Launched in 1955, the Ingenieur borrowed the soft iron inner case of the WWII-era Mark XI military watch and added a new in-house movement.
Offered originally in date and non-date format, the 666 is one of the most hard to find vintage IWC models on the market today. A combination of limited production and its unassuming looks (a large number of them were probably scrapped by people who didn’t know they were something special), not to mention the perils of time, make early examples such as this one a highly desirable “pre-Genta” Ingenieur.
Perhaps most interestingly, the Reference 666 Ingenieur featured anti-magnetic protection up to 80,000 amperes per meter.
The watch was produced in 1960 and it’s in an amazing condition given the age.
