AI Appraisal Estimate

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.

I have virtually examined this vintage Glycine Combat Diver, a highly sought-after reference from the late 1960s. The 'gloss-to-matte' transition dial with the stylized hexagonal shield logo is characteristic of the period. The heavy cream patina on the tritium markers and sword hands is excellent, though the visible degradation on the 'Automatic' and depth rating text suggests historical moisture exposure. The countdown bezel remains largely intact, which is critical for this model's value. Market demand for 1960s technical divers remains robust, with Glycine's Combat and Airman lines seeing significant appreciation among 'tool watch' collectors. While the scratches on the crystal and case wear are 'honest,' the moisture-vignetting at the dial's edge may indicate internal movement corrosion. Historically, these pieces outperform comparable divers due to their unique aesthetics. However, a conclusive appraisal requires physical inspection. Authenticity cannot be confirmed via image alone; I would need to verify the caliber 1700/01 movement, check the serial numbers between the lugs, and ensure the crown is original. A full mechanical service history or original 'providence' documentation would further solidify the upper range of this estimate. Without opening the case back, the state of the movement and its timekeeping accuracy remain unknown variables that could impact the final valuation by several hundred dollars.
