AI Appraisal Estimate

This is a vintage Wittnauer quartz wristwatch featuring a classic rectangular 'tank' style case with a gold-tone finish. The dial is characterized by a vertical linear texture (pinstripe guilloche pattern) and a single small round-cut diamond or high-clarity crystal set at the 12 o'clock position. The dial features the 'WITTNAUER' brand name and the 'Quartz' designation in cursive script. It is equipped with simple baton hour markers and slim gold-tone hands. The case shows significant signs of wear, including multiple surface scratches, pitting in the gold plating, and visible dirt or oxidation along the bezel edges. The crystal appears heavily scratched and potentially cracked, particularly across the upper left quadrant. The watch is fitted with an aftermarket or period-correct gold-tone expansion band featuring a textured brick-link design, which also shows accumulation of debris between the links. Based on the quartz movement and typography, this piece likely dates to the 1980s or 1990s. The overall condition is fair to poor, requiring professional cleaning and crystal replacement.

I have conducted a visual examination of the vintage Wittnauer Men’s Quartz Tank Watch. The piece exhibits the stylistic hallmarks of the 1980s quartz era, including the characteristic 'pinstripe' dial and minimalist diamond-dot index. While the brand carries heritage as a subsidiary of Longines, this specific model represents a mass-produced period for the company. The condition is significantly compromised; I note heavy surface abrasions on the crystal and pervasive pitting of the base-metal gold-tone plating, suggesting moisture exposure or heavy wear. The expansion band is non-original and shows signs of DNA/debris accumulation. High-end examples in 'New Old Stock' (NOS) condition typically fetch $100-$150 on the secondary market. However, due to the poor physical condition and the functional uncertainty of the quartz movement (which may have battery leakage damage), this item is valued primarily for parts or as a restoration project. Authenticity is likely authentic given the low value of counterfeiting this specific model, but I cannot confirm movement integrity or gold-plate thickness from images. For a definitive authentication, I would require an internal inspection of the movement for Longines-Wittnauer signatures and a test of the battery leads for corrosion. The current market for mid-century quartz is soft, preferring steel-cased watches with higher mechanical merit.
