This early 1970s IWC Automatic is in outstanding, all original condition, and features a one-piece stainless steel case with a solid case back. The movement drops in from the top. I think it is a very cool design and certainly very strong. It was used to improve water resistance. Omega made this style very famous in the 60s. 

The watch features the IWC’s Cal. 8541B movement with automatic winding. This beautifully finished movement was one of IWC’s best and is the same base movement in the Ingenieur watches (which have easily fetched $10,000+ at auction). Very high grade, easily a chronometer grade 

movement and like the case, it is built like a tank.

The signed stainless steel case measures 36.2 mm square without the crown. Great angles and finished is high polish with a sun-burst pattern on the bezel. The stainless steel crown is an original IWC “Fish” crown. A wonderful classic design that never goes out of style. The dial features a perfect silver background finish. It’s accented with applied two-tone black and stainless steel bar markers and matching two-tone, black, and steel hands. All are original, untouched in condition.

The watch comes fully serviced and is keeping very good time. Along with service, we ultrasonically cleaned after doing some light refinishing. Also during service, the watch also received a new mainspring and crystal. We paired the watch with a genuine crocodile strap in dark brown.
