Box compartmentalized wooden

Charming wooden box with a small golden clasp and a marking with the name of incarex painted on it. Inside, 3 compartments each with small numbered notches. It is, according to my research, a case that contained elements related to watchmaking (incarex besançon, springs for watchmaking). It still has a technical sheet glued to the inside. I think it's from the 60s. It is in good structural condition but does not hide its age: scratches and marks on the wood, varnish faded in places, the clasp has partly lost its gilding. It measures 25.5 cm by 16.5 cm for a thickness of 6 cm. It weighs about 500g. I offer other small boxes in my shop, you can find them by clicking on "see other products from this seller".
