AI Appraisal Estimate

This is a Must de Cartier 21 wristwatch, a classic timepiece known for its distinctive design elements. The watch features a round, stainless steel and gold-plated case typical of the 1980s or 1990s style period. A key characteristic is the fixed bezel, which displays engraved black Roman numerals representing the hours. The dial itself is a light, champagne or silver-toned center, appearing minimalist with simple blued-steel or dark-colored hands, including a central seconds hand. The Cartier logo is visible at the top of the inner dial. The crown is located at the 3 o'clock position and appears to features the signature Cartier synthetic blue spinel or sapphire cabochon. This specific model utilizes a unique t-bar lug system to connect the case to a black, pebbled-texture leather strap, which shows minor signs of creasing consistent with use. The overall condition appears fair to good; there is visible surface wear and fine scratching on the bezel and case consistent with an older, worn luxury watch. The plating shows slight fading in high-contact areas. This watch likely utilizes a quartz movement, a standard for the 'Must de Cartier' line which aimed to make the brand's luxury aesthetic more accessible.

I have completed a visual assessment of the Must de Cartier 21 wristwatch. This piece represents the quintessential 1980s-90s 'entry-level' luxury market. The Roman numeral bezel and synthetic spinel cabochon crown are correct for this reference. Based on the images, the case displays significant surface abrasions and some softening of the engraved numerals, suggesting a history of regular wear. The gold plating shows early signs of thinning on the t-bar lugs. The leather strap, while likely an aftermarket replacement given the wear patterns, remains functional. Current market demand for the 'Must' line is buoyed by the 'vintage Cartier' trend, though quartz models are valued lower than mechanical counterparts. Comparables for this model in 'Good' condition generally trade between $600 and $1,100 depending on the integrity of the gold plating and dial cleanliness. The value is capped here due to visible bezel wear. My authentication is limited to visual characteristics; a photograph cannot verify the quartz movement's functionality or internal markings. While the proportions and typography align with authentic production, a definitive appraisal requires a physical inspection to confirm the weight, the serial number's engraving depth, and the movement’s authenticity. I would also recommend checking for original box and papers, which can add a 15-20% premium. Without opening the case back, the risk of a high-quality period replica cannot be entirely excluded.
