Miniature spheric golden (18k gold) pendant watch, so-called "Boule de Geneve".
The watch is miniature, diameter is only 17mm.
To achieve such miniature size, the movement has quite complicated construction.
The winding mechanism is unusual - movement is winding by rotating the bezel.
The movement layout is divided by two layers, the barrel is located below the going train and escapement.
According information provided by Cortrie Auctionhouse from Stuttgart, Germany, this type of winding was patented by LeCoultre.
It's very well may be, as quality and finishing of the movement is on par with LeCoultre period watches.
This watch is unsigned, but very similar watches were retailed by grand companies as Patek Philippe, Vacheron Constantin and others.
The watch appears to be in good condition.
The movement is in running condition.
Cosmetic condition is also ok, please see photos.
Watch comes with 18k gold chain.
Total weight is 17.5 grams.
