Thank you very much for viewing this item on Mercari. This item is a silver pocket watch case remnant from the Meiji era, made by Orosti & Co., approximately 5.8 cm in diameter and 2 cm thick. It is over 100 years old. Orosti & Co. was a well-known trading company in the Meiji era that imported Swiss-made watches to Japan, and was prominent in the field of merchant watches. The pocket watch case is stamped with the Orosti & Co. name and the silver purity mark, giving it a distinct Meiji era feel. The case also has a celluloid transparent case, which has cracks. Therefore, it requires repair and modification. Please understand that this item is being sold either as is, to appreciate its historical atmosphere, or as a junk collection for parts. Also, please refrain from purchasing if you are particular about the weight of the silver, etc. For those who are interested in this rare, large merchant watch case junk collection from the Meiji era, and for overseas collectors who occasionally purchase such items, please consider the item as described. Please consider this as the shell of a pocket watch that has passed through more than 100 years.
