From the photo, this appears to be a Certina Bristol 195 dress watch from the late 1960s to early 1970s. Here are some observations: • Brand: Certina (Swiss) • Model: Bristol 195 (printed on the dial) • Movement: Most Bristol 195 models were manual-wind, although some automatic versions exist. A photo of the case back or movement would confirm. • Case: Gold-tone, likely gold-plated rather than solid gold (solid gold cases are usually hallmarked on the case back). • Dial: Silver sunburst with applied gold baton indices and a date window at 3 o’clock. • Crystal: Acrylic, showing scratches consistent with age (these can often be polished out with Polywatch). • Strap: Appears to be a modern replacement leather strap rather than the original. Condition Overall I’d estimate it as good vintage condition: • Dial appears clean with only light aging. • Hands and markers have some patina. • Case has visible wear to the plating, especially around the bezel and lugs. • Crystal has scratches. • Replacement strap. Estimated value Assuming it is running well: • Needs service / not running: approximately US150-200 • Running and keeping reasonable time: US$300-450 • Freshly serviced with excellent cosmetics: US$300–550 Knowing it contains the original Cal. 25-661 increases confidence in the valuation.
