Overview A vintage Minerva mechanical stopwatch (pocket-watch style). The white dial features a clear multi-scale layout: an outer 0–100 “decimal/percentage” scale (often used for industrial or sports timing conversions) and an inner 0–60 seconds track, plus a 30-minute counter at 12 o’clock. The overall design is highly legible, with a strong tool-watch character typical of early mechanical timers and appealing for collectors. The watch is currently in working order and runs (no long-term accuracy test performed).
