It's one of the smallest pocket watches ever made.
In fact, it's too small to be worn in pocket and more suitable to be attached as pendant. Diameter is less than 20mm, height without bow is 26mm, weight is 8,5 grams.
Very rare size.
The watch is based on LeCoultre movement, Calibre 5, also known as Revolver-Calibre. It was smallest LeCoultre movement and advertised as company achievement in it's brochures. This small 6 lines movement was produced only in "extra fine" quality.
Watch is decorated with tiny rubys and nice big diamond of old rose cut.
Diameter of the diamond is 5mm, weight is roughly 0.4 carats.
The dust cover signed by Bart in Besançon by French retailer and "1re qualité soignée" for "1st immaculate quality".
The case is Swiss made and bears 18k French import hallmark.
The watch appears to be in good condition.
The movement works, but I don't guarantee time keeping.
Dial seems to be free from defects.
Case has minor wear.
Later plastic crystal, original hands.
