Thullier - A.Geneve Argento - Earlier than 1850

Magnificent pocket watch from the prestigious Thuillier (A.Geneve) with a signed movement, a work of art dating from the late 18th century.
The watch does not work, but it seems complete to me and I recommend a restoration because it is really worth it.
Complete with its case back, also in silver.
Esthetic condition, I would say, good
Diameter 40 mm
