Vintage Glycine Combat Diver Automatic Wristwatch

This is a vintage Glycine Combat diver's watch featuring a stainless steel case and a distinctive rotating bezel. The dial is a textured matte black, exhibiting a heavy patina consistent with age. It features round luminous hour markers, a triangular 12 o'clock marker, and a rectangular 6 o'clock index. A date window is present at the 3 o'clock position. The hands are a large 'sword' or 'plongeur' style with heavily aged tritium or radium luminous infill that has turned a cream-to-yellow hue. The 'Glycine' logo is displayed in a stylized hexagonal shield at the top center. Below the hands, the dial is marked 'AUTOMATIC' and '200m = 660ft' in red, though the red text has faded significantly over time. The external countdown bezel features large, cream-colored Arabic numerals at the 10-minute intervals. Condition-wise, the watch shows significant honest wear; the crystal has multiple scratches, the lume shows signs of degradation and discoloration, and the dial appears to have some tropicalization or moisture-vignetting around the edges. This piece likely dates to the late 1960s or early 1970s, representing a classic era of mechanical tool watch design known for rugged construction and functional legibility.
