This is an item for sale to organize my collection. It is in working order. I think it's in relatively good condition because it hasn't been used much. The case width is 40mm (excluding the crown). Please understand that this is a used item. Even if it is confirmed to be working at this stage, it may stop working upon arrival. Please be aware that due to the nature of used items that have not been maintained, repairs may be necessary. Also, please understand that we have not checked for daily variations, etc., before purchasing. Thank you very much!
