Undoubtedly one of the creators for some of the most beautiful and coveted vintage chronographs, Longines also has a lesser known history in dive watches of which the present watch is a smashing example.
To guarantee water resistance, Longines contacted case manufacturer Ervin Piquerez who had patented a so-called “super compressor” case, whereby the deeper the watch went, the tighter the back sealed against the gasket.
Instead of an outer bezel to time dives, Longines opted for a very elegant rotating inner bezel that can be controlled via the crown located at 2 o’clock. The appeal of the present watch features a rich black lacquer dial that has turned ‘tropical’ over time where part of the dial has turn into a lighter caramel tone, enhancing the desirability of this rare and beautiful example.
