AI Appraisal Estimate

This is a vintage Tissot PR 516 automatic wristwatch, likely dating from the 1970s. The watch features a tonneau-shaped case with a gold-toned plated finish and a distinct fluted or engine-turned bezel. The sunburst gold dial is accented with raised rectangular hour markers and a day-date complication at the 3 o'clock position, showing the day in Spanish (MIE for Miércoles). The dial is marked with the Tissot logo, 'TISSOT SWISS', and the model designation 'AUTOMATIC PR 516' in black and red text. The watch is fitted with a two-tone integrated jubilee-style bracelet with visible wear to the plating, particularly on the rounded center links. As for condition, the acrylic crystal shows significant surface scratches and scuffing throughout. The case also exhibits minor pitting, scratches, and some wear-through of the gold plating on the lugs and edges. This piece represents the 'Particularly Resistant' (PR) line from Tissot's racing-inspired era, showcasing typical 1970s Swiss craftsmanship with a robust mechanical movement.

I have conducted a visual examination of the Vintage Tissot PR 516 Automatic. The watch exhibits high aesthetic consistency with 1970s Swiss production, specifically the 'Particularly Resistant' line. The day-date complication in Spanish (MIE) suggests a variant intended for the Hispanic or Latin American market. My assessment indicates a watch in 'Fair' to 'Good' vintage condition. The movement appears authentic based on the dial layout, though the significant scuffing on the acrylic crystal and the visible plating wear on the integrated jubilee bracelet and case edges diminish its overall market value. Market demand for Tissot PR 516 models remains steady among entry-level vintage collectors due to their racing heritage, yet gold-plated examples generally command lower prices than stainless steel versions. Comparables for this specific tonneau-shaped reference in similar condition typically hammer between $250 and $400. The primary value drivers here are the original integrated bracelet and the mechanical automatic movement. Limitations of this appraisal include the inability to inspect the caliber (likely a Cal. 2571 or similar) for corrosion, service history, or timing accuracy. I cannot verify the integrity of the water resistance or the crown's threading from images alone. A full authentication would require a physical case-opening to verify the serial number against Tissot archives and a movement inspection to ensure all components are period-correct and original. Functional testing of the day-date quickset and power reserve is also necessary for a definitive valuation.
