AI Appraisal Estimate

An antique silver pocket watch with a white dial, black Roman numerals, and a seconds sub-dial. The inside of the caseback shows hallmarks. It has a chain attachment loop.

Based on the visible hallmarks inside the case back, which appear to be British silver hallmarks, and the style of the pocket watch, it is likely a late 19th or early 20th century silver pocket watch. The condition appears good for its age, although functionality cannot be assessed from the image. Identifying the specific maker or origin from the obscured dial and marks is difficult without clearer images. The value would depend heavily on the maker, the movement's quality, and the actual silver purity and weight, as well as working condition and any complications. Without further information and a hands-on inspection, the estimated value is based on similar period silver pocket watches in potentially good condition.
