1962 IWC Auto Cal. 8531 'Calatrava' Silver Dial 36.5mm R 647A
Here we have a curvaceous 1962 IWC Auto Cal. 8531 'Calatrava' Silver Dial R 647A featuring a rare ‘Jumbo’ 36.5mm brushed and polished stainless steel round case that sits comfortably on your wrist, thanks to the curved drilled lugs. The brushed flanks lead to a lug-to-lug length of 43mm and a case thickness of 10.5mm, and on the right side is a push/pull crown with a coin edge for grip. A thin, smooth polished bezel holds a domed crystal above a striking sunburst silver ‘Calatrava’ dial, an outer ring of pips mark the minutes surrounding applied polished facet baton indexes marking the hours; they magically play with the light as you rotate your wrist, elegant slim Dauphine hands are complemented by a tapered second hand, at 3 o’clock we have a framed date window with cyclops magnification, at noon you find the original International Watch Company motif in its distinctive swirling script and at 6 o’clock “Automatic” completes this incredibly sophisticated dress watch. On the reverse, a polished and brushed case back, inside an automatic IWC Cal. 8531, 21 jewels, based on the IWC-exclusive Pellaton automatic winding system, developed by Albert Pellaton in 1950, this new self-winding mechanism was deemed groundbreaking for its era. It revolutionised the traditional approach by enabling the transfer of energy from the bidirectional rotor to the mainspring. This innovative solution proved to be considerably more efficient compared to other self-winding movements of the time. It comes paired with its well-suited aftermarket 18mm leather strap and pin buckle.
