IWC Calatrava No-Date C.853 34.0mm 1962

Coming from the archives back before IWC began to use reference numbers. This sleek and pristine IWC Calatrava comes with a sleek no date combination perfect for collectors who value simplicity. Matched with its perfect combination of super clean patina, one of the best unique patterns formed naturally with the years gone past. Ageing perfectly like fine wine.

In addition, this timepiece comes freshly serviced with all parts laid out by our professional watchmaker for all to see in the images above. Little to no other dealers do this and it’s a testament to full transparency here at Montre D’or. With the Caliber C.853 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
