CHENXI is definitely not a "Swiss watch brand" and I am very skeptical about their "water resistance". Splash guard I guess. Waterproof, questionable. I assume it's a Japanese quartz watch. Especially since there were 368 yen price tags in the box. Make them for about $3.40 each at current exchange rates. Although the $30 price tag is a bit steep, they're probably still cheaper than buying them in bulk from AliExpress. "Throw away” watches when traveling if they are stolen.
