AI Item Analysis

This item is a mechanical stopwatch featuring a silver-tone metal case and a white analog dial. The primary dial displays large Arabic numerals from 5 to 55 in black, with '60' highlighted in red at the twelve o'clock position. A smaller sub-dial located at the top center displays a 30-minute counter with black numerals and a red '30'. Centrally positioned on the lower half of the dial is a cursive script signature that appears to read 'Precista'. At the very bottom edge, the text 'SWISS MADE' is visible in a small typeface. The device features a large fluted crown at the top for winding and operation. The item appears to be in good cosmetic condition, with some minor surface wear and light scratches visible on the polished bezel. Stylistically, the piece is consistent with mid-to-late 20th-century timing instruments often used in sporting or industrial settings. While markings such as 'Swiss Made' and the brand signature are visible, they have not been physically verified for authenticity and are treated as evidence consistent with that attribution pending expert inspection. The hands are black and pointed, with the main second hand resting precisely at zero.

AI Appraisal Report

Based on my visual examination of the provided image, this mechanical stopwatch bears markings consistent with the Swiss-made Precista brand, likely dating to the mid-to-late 20th century. The piece features a classic 60-second dial with a 30-minute sub-dial and appears to be in well-maintained cosmetic condition, showing only light surface abrasions to the polished metal case. My valuation range of $125 to $225 is based on the assumption that the 'Precista' signature and 'Swiss Made' markings are accurate and that the mechanical movement remains in functional condition. This estimate reflects the general market for vintage timing instruments often used in sporting or industrial sectors. I cannot verify the internal movement, nor can I determine the metal purity or complete mechanical integrity from a photograph alone. For a confirmed identification, it would be necessary to have an in-person inspection of the movement for appropriate hallmarks and reference numbers. Furthermore, provenance or documentation regarding its service history would be required to support the higher end of the range. If the item were found to be a modern reproduction or if the signature cannot be verified as synonymous with the original manufacture, the value would likely decrease to a decorative range of $30 to $50. Demand for such pieces is currently steady among collectors of functional horology, though condition and the accuracy of the manual winding mechanism are the primary drivers of price in this category.
