Delbana mechanical wristwatch (not authenticated)

This is a vintage mechanical wristwatch featuring a circular silver-toned case, a light-colored patinated dial, and an expandable metallic link bracelet. The dial displays prominent Arabic numerals at the 12, 3, 6, and 9 positions, interspersed with arrow-style hour markers. The text visible on the dial includes the script brand name reading 'Delbana' below the 12 o'clock position, along with secondary text reading 'ANTIMAGNETIC' and 'SHOCK RESISTED', and 'MADE IN FRANCE' near the bottom margin. The hands are slender with a contrasting central sweep second hand. The case shows noticeable pitting, tarnish, and surface wear consistent with age and prior use. The crystal displays minor scratches. The identification is based on the legible brand text on the dial, but the item remains unauthenticated and its internal components have not been inspected. The style suggests a mid-20th-century manufacture, likely dating from the 1950s to 1960s. The attachment is a flexible stainless steel expansion band showing typical wear.

Based on what I can see in the photograph, this vintage mechanical wristwatch bears script text on the dial reading 'Delbana', alongside 'ANTIMAGNETIC', 'SHOCK RESISTED', and 'MADE IN FRANCE'. The piece features a circular silver-toned case, a patinated dial with prominent Arabic numerals, and an expandable metallic link bracelet. I can't verify from a photo whether the internal components are functional, nor can I evaluate the quality of the movement. Physical inspection would be needed to confirm the internal condition and the materials used. The case exhibits noticeable pitting, tarnish, and surface wear, while the crystal shows minor scratches. The estimated value range of $100-250 assumes the working hypothesis that the watch is a period-correct piece associated with the Delbana brand. General market demand for mid-20th-century mechanical wristwatches of this tier tends to be modest unless they are from highly sought-after luxury lines or in pristine condition. Because this item remains unauthenticated, its market value depends entirely on professional verification; an unauthenticated or replica piece of this type would typically sell for significantly less, closer to $30-50 as a decorative or parts watch. To fully confirm the nature and authenticity of the watch, an in-person examination by a horological expert, movement inspection, and potential component verification would be required.
