A rare and beautiful unpolished solid stainless steel chronograph by Croton of Switzerland in an “clamshell” style early waterproof case with stunning original dial and Venus caliber 210 movement freshly serviced within and keeping excellent time.  To achieve a waterproof case design was an enormous accomplishment back in the 1940 and this sandwich style design was the first truly successful model on the market.  Used by many of the top manufactures at the time such as Gallet and Cyma/Tavannes the seal is created by housing the movement and dial in a deep sealed case back with gasket protected pump pushers and crown. The bezel is tightened over a special flanged crystal and corresponding gasket to sandwich the back to the front using 4 screws on the back of each lug.  This example is in truly superb cosmetic and mechanical condition proving that the design not only worked by stood the test of time.  It is possible this particular case was produced by the famous house of Spillman as the sharp, faceted lug design is typical of other well known Spillman model case designs. An exceptional all original timepiece in unpolished lightly warn condition with near mint original factory dial from the famous house of Croton, Switzerland!
