The watch in your photo appears to be a Numa-Matic vintage automatic wristwatch, likely dating from the 1960s. Here are some observations: • Brand: Numa-Matic (a smaller Swiss private-label brand rather than a major manufacturer). • Movement: “Matic” indicates it is an automatic (self-winding) mechanical watch. • Case: Gold-tone, likely gold-plated rather than solid gold (solid gold cases are usually marked 14K, 18K, or 0.585/0.750 on the case). • Dial: Silver sunburst dial with applied baton hour markers and dauphine-style hands, typical of mid-1960s Swiss dress watches. • Crystal: Acrylic (plexiglass), showing scratches consistent with age. These can often be polished with products like Polywatch. • Strap: The leather strap appears to be a later replacement, not original to the watch. Estimated value Based on the visible condition: • Running and keeping good time: approximately US$175–200 • Recently serviced and in excellent condition: US$175–300 funcțional !
