The all stainless steelcase shows honest wear with no visible signs of oxidation. The outer edge of the case back is stamped "66071" with "FULL STEEL,""SWISS MADE,""BREV +,""587551,""SUPERWATERPROOF,""305,""AUTOMATIC" and "INCABLOC" stamped along the inner edge and "PHILIP WATCH" followed by "CARIBBEAN,""TRIPLE-SAFE" and "BREV DEM + 5292/68" stamped in the center.The crystal, which I believe to be original, shows crazing which can only be seen at certain angles and lighting conditions.
