This is a CASIO G-SHOCK Baby-G X-treme BGX-131. The battery has been replaced with a new one before listing. It has hardly been used, so the condition is very good, almost like new. The rubber logo on the strap has peeled off due to hydrolysis. There is a slight discoloration on the strap due to long-term storage, but it can be removed with detergent. It comes from a non-smoking and pet-free environment, so there is no concern about odors or stains.
