Vintage Must de Cartier Square Watch with Mesh Bracelet

This is a vintage ladies' wrist watch featuring a square case with a distinctive gold-tone finish. The watch is marked with the 'must de Cartier' signature on the upper portion of the dial and the interlocking 'CC' logo at the 6 o'clock position. The dial is a dark, oxblood or chocolate brown color, characteristic of the Must de Cartier line from the late 1970s and 1980s. The bezel is embellished with a hobnail or 'Clous de Paris' textured pattern, which adds a sophisticated geometric detail. It is paired with an integrated mesh or milanese-style flexible bracelet in a matching gold tone. The crystal appears to be mineral glass and shows significant surface scratching and abrasions centrally. The case and bracelet exhibit signs of age-related wear, including minor tarnish (patina) and light scuffing, particularly around the edges of the bezel. The hands are gold-toned, though only the hour hand is clearly visible in the provided image. This piece represents the luxury accessible movement of the Cartier brand during the late 20th century, likely featuring a vermeil (gold over silver) case construction typical of this specific collection.

I have conducted a visual examination of the Must de Cartier Square Vermeil watch. The dial features the era-appropriate oxblood lacquer and 'double C' logo, while the Clous de Paris bezel and integrated mesh bracelet suggest a production date from the late 1970s to early 1980s. The aesthetic remains highly desirable due to the current market trend favoring vintage 'tank-style' and mesh-bracelet geometries. Condition is a significant factor here. I observe heavy scratching on the crystal and visible oxidation/tarnish on the vermeil finish. If the gold plating has worn through to the 925 silver base (brassing), the value sits at the lower end of the range. Conversely, if the patina is superficial, the value improves. The 'Must' line was Cartier's entry into accessible luxury; while not as rare as solid gold pieces, the specific combination of the square case and mesh bracelet is less common than the standard leather-strap Tank. Authenticity cannot be fully certified from images alone. A physical inspection is required to verify the '925' hallmarking on the case back, the movement's caliber (likely a manual wind or early quartz), and the presence of the hidden Cartier signature in the Roman numerals (if applicable to this dial variant). I would also need to verify the integrity of the bracelet's clasp and ensure the dial hasn't suffered from 'spidering' or cracking beneath the scratched crystal. Full authentication would involve opening the case back to inspect the movement and checking any available original papers or box.
