Here is an extremely rare IWC Aquatimer, which dates to 1968. This is from the second series of Aquatimers and most likely produced in quite small quantities. The first Aquatimer was launched by IWC the previous year in 1967, so this is still an early Aquatimer. This is not an easy watch to find and especially this version. You can see this example has a small, multi-faceted, screw-on bezel to pressure fit the glass crystal. This system apparently did not work well underwater and was in production for a short time. In fact owners of this watch had them sent back to IWC who sent them a new watch with a redesigned system that did not feature any bezel and these were in production into the 1980's. The IWC museum has this watch in their collection, but the version without the screw-on bezel. This is an early dial with the old style "International Watch Company" script and no IWC above. While the case is worn, I elected not to have it redone, originally it would have had a brushed sun burst finish, but the dial is excellent. The watch features an in-house IWC 8541 Pellaton movement (unlike the modern counterparts that use ETA's). The watch has been serviced by Shane Ede and it keeping time to -7 seconds a day. Nice slower beat movement and it's hacking. The top crown is original, the bottom crown is unsigned. 40mm excluding crown, large size compressor. Yes in terms of vintage divers from the 1960's, everyone is on the Tudor, Rolex bandwagon. But this a really much more interesting piece, from the dial, to the compressor case to the movement and much rarer. Reduced US$3495 OBO, includes paypal and shipping Canada/US.
