This is the J-AXIS quartz wristwatch DL800-BR. It is 10 ATM water resistant (excluding the strap). Although the product website listed it as a men's watch, I purchased it for my daughter's commute for about 4,000 yen. The case (face) size is 31mm in diameter and 8.5mm thick. It's a size and design that can be used by both men and women. It's been 5-6 years since I bought it, and it's still working fine. The synthetic leather strap is badly worn, so the strap needs to be replaced. #J・AXIS #J-AXIS #wristwatch #quartzwatch #analog #10atmwaterresistant #brown #DL800-BR #DL800 #menswatch #ladieswatch #commute #school Strap color...Brown Operation...Good
