ORIENT's Bambino 38 series, a solar-powered quartz wristwatch. Product number is RN-WK0004L. Black dial version. With a case diameter of 38.4mm, it's very easy to wear and suitable for both formal occasions and everyday wear. I wore it four times to the office, but I'm selling it because I've switched to a mechanical watch. I purchased it on Amazon, so I don't have a warranty, but it works perfectly and is in near-new condition. Please feel free to ask if you have any questions.
