[Regarding the sale of wristwatches] We do not inspect the functions of the wristwatches we sell. We will not answer questions such as "How is the function of XX?" or provide operational instructions. Even if the watch is running at the time of listing, the hands may slow down or the battery may run out over time. In that case, please have the battery replaced by the buyer. Also, we are not responsible for any battery failure or other problems that may occur after arrival. There is no warranty. Please refrain from requesting partial refunds. If you are concerned, we recommend purchasing from a physical store. We do not accept belt length adjustments or battery replacements before purchase, as these can lead to problems. Please request these services at your nearest watch store. Basically, the items in the photos are all that are included. If the manual or extra links are not shown in the photos, they are generally not included. No photos of the watch being worn. Slight price reductions are possible, but only those who are serious about buying should request a price reduction from the comments and provide their desired price for negotiation. Template comments or those without a stated desired price will only receive a 100 yen discount. Also, unreasonable price offers will be blocked. #KuroNekoNig'sWristwatch
