AI-assisted summary
Description from the seller
Beautiful and rare 'secret' cocktail watch (cuff/watch hidden) in solid 18-carat gold (750‰) from circa 1950–1960.
The clasp concealing the watch forms a magnificent figurative motif in the shape of a belt/band loop, entirely enhanced by genuine diamonds size eight-to-eight / brilliant on platine or white gold.
Characteristics & Materials:
Metal: Yellow gold 18 carats (750/1000).
Official hallmarks:
Official French Eagle Head assay mark guaranteeing 18k gold present on the back of the case and on the clasp.
Master jeweler/linkmaker hallmark (in a lozenge).
Stones: Pavé of genuine diamonds on the loop and on the secret clasp.
Bracelet: Wide flexible gold ribbon with chevron / braided mesh, secure click-clasp with eight safety.
Dial & Brand: Cream/silver dial signed COSMOS, applied gold-tone markers in relief, gold hands.
Gross total weight: ~45 grams (net 18k gold weight estimated to be over 41 g).
Condition and Function:
Miniature mechanical manually-wound movement functional: the balance ticks regularly, the watch winds up and sets the time without issue. (Routine servicing may be advisable given its age).
The secret-clasp spring operates perfectly and closes accurately.
Very good condition for a jewel of this era, with light wear marks consistent with age.
