This is a KNOT wristwatch. It is water-resistant, with sapphire glass and a stainless steel case. The model number is 316L-CS-36. There are some minor scratches from daily use, but it is generally in good condition. I have confirmed that it works, but I have removed the battery just in case, so please install one yourself. The components are as follows: ・Watch body ・Genuine leather strap ・Box Thank you.
