Selling due to replacement. ※ The screw in the bottom right of the first photo is missing! However, I ordered and installed an M2.5 stainless steel screw from Misumi. (Not original) It seems to work without any problems. Last photo: The button is a little difficult to respond to unless pressed firmly (when using the stopwatch function). ※ No instruction manual or other accessories included. ※ Price negotiation is possible (I will consider it a little). ※ Please understand that this is a used item before purchasing. ※ Returns are not accepted. Please understand and agree before purchasing.
