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 a super clean silver sunburst dial, preserved excellently despite its age.

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.
