Released in 1991, this is the first Swatch with a stopwatch function. I understand that the total number released was quite small, making it a rare item with high collectibility. Functionality has been confirmed, but please replace the battery before use. The strap is also clean and I think it can be used as is. This is a used item, so I would like to sell it to someone who understands this. Please refrain from purchasing if you are overly concerned about details. The included items are all shown in the images.
