AI Appraisal Estimate

This is a TAG Heuer Formula 1 Grande Date Chronograph, likely dating from the late 2000s or early 2010s. The watch features a robust 44mm brushed stainless steel case with a distinctive unidirectional rotating bezel engraved with oversized Arabic numeral hour markers. The dial is black with a 'Grande Date' oversized date window positioned at 6 o'clock. It features two sub-dials: a chronograph 30-minute counter at 9 o'clock and a continuous seconds sub-dial at 3 o'clock. The dial is punctuated by a large luminous '12' at the top, applied baton indices, and a 'TAG Heuer Formula 1' logo in white and red. The hands are polished and treated with luminous material for visibility in low light. It is powered by a precision Swiss quartz movement. The watch is presented on a matching brushed stainless steel three-row link bracelet with a folding clasp and safety latch. Notable condition issues include visible surface scratches and 'desk diving' marks across the bezel, case, and bracelet links, particularly on the 10 and 11 o'clock positions of the bezel. The crystal appears clear, though minor micro-abrasions may be present. This model represents a blend of TAG Heuer's racing heritage with practical sports utility, showcasing high-grade 316L stainless steel construction and a screw-down crown for water resistance.

Based on my visual inspection of this TAG Heuer Formula 1 Grande Date (Ref. CAH1010), the watch presents as a genuine example of the brand's entry-level sports chronograph from the transition era of the late 2000s. The 44mm case displays characteristic signs of heavy daily wear, particularly significant scuffing on the PVD-coated titanium carbide bezel and brushed steel bracelet links. These 'desk diving' marks and bezel abrasions at the 11 o'clock position slightly diminish the secondary market value compared to 'New Old Stock' examples. The dial alignment, logo printing, and the unique dual-wheel 'Grande Date' complication appear consistent with factory standards. This model remains popular due to its robust size and TAG Heuer's racing pedigree, though quartz movements generally hold less value than their mechanical counterparts. Current market comparables for Ref. CAH1010 in 'Good' condition fluctuate between $600 and $900. The lack of original boxes and papers prevents it from reaching the premium tier of $1,000+. Important: My assessment is based solely on high-resolution images. Final authentication is limited without physical inspection; I would need to open the case back to verify the Ronda or ETA quartz movement caliber and check for signs of moisture ingress. Furthermore, an in-person examination of the serial number against TAG Heuer's 'Warranty Activation System' would be required to confirm definitive provenance and guarantee that no aftermarket parts have been integrated during previous servicing.
