AI Appraisal Estimate

This is a vintage mechanical open-face stopwatch, likely of Swiss origin, featuring a decimal recording dial. The case appears to be constructed of polished nickel-silver or chrome-plated brass, showing a minor circular bow and a crown at the twelve o'clock position for winding and start/stop functions. A secondary pusher or reset mechanism is visible near the shoulder. The dial is white enamel or painted metal, featuring bold black Arabic numerals tracking a 0-100 decimal scale (specifically measuring 1/100ths of a minute). A smaller sub-dial is located at the top center for recording elapsed minutes. The brand name 'MEYLAN' is visible below the center point. The center-mounted blued steel sweep hand is present. The crystal appears to be acrylic and shows some minor surface scratches and localized glare in the provided image. The overall condition suggests a mid-20th-century manufacture date, potentially for industrial or laboratory timing purposes. There is visible oxidation and light patina on the metal casing, consistent with regular use and age. The hands appear original, and the dial remains remarkably legible with minimal yellowing.

I have completed a visual examination of this vintage Meylan decimal stopwatch. The piece is a classic mid-20th-century tool designed for industrial time-study and laboratory use, utilizing a 1/100th of a minute scale rather than standard seconds. The white dial remains remarkably crisp with legible Arabic numerals and original blued steel hands, which significantly helps the valuation as replacements would diminish historical integrity. The chrome or nickel plating shows expected surface oxidation and minor micro-scratching on the acrylic crystal, consistent with an authentic 'industrial-use' provenance. Meylan is a respected name in Swiss horology, often associated with high-quality movements from Lemania or Minerva. Currently, the market for mechanical stopwatches is stable but niche, primarily driven by tool-watch collectors and enthusiasts of vintage scientific instruments. Comparables for decimal-dial Meylan units typically range from $200 for worn examples to over $500 for those with original boxes or military markings. The value of this specific item is hampered slightly by the lack of visible movement photos to verify jewel count and caliber condition. Limitations: This appraisal is based solely on high-resolution imagery. A physical inspection is required to test the mechanical oscillation, power reserve, and the 'crispness' of the reset-to-zero function. To fully authenticate the piece and potentially increase this valuation, I would need to open the case to verify the movement's serial number and signs of previous servicing. Full provenance documentation or a surviving original case would provide further value premiums.
