Thank you for viewing. This is a genuine MoonSwatch rubber strap, as shown in the images. As expected from an official Swatch product, the quality is high and it looks great. I purchased it new, but I have multiple straps and won't be using this one for a while, so I'd like to sell it to someone who wants it. The size is XL. It's a web exclusive, so I confirmed the size with a sample at a Swatch store. Based on the size settings from slender women, I think L to XL would be suitable for most men. I chose this size to have a little extra room, and I think it will fit many men. I will ship it anonymously the day after your purchase. Thank you very much. Black rubber strap made of bioceramic, stylish with the Speedmaster logo. - Model: MoonSwatch Black/Black Rubber - Color: Black - Style: Rubber Strap - Material: Bioceramic - Size: Standard Size - Features: With Speedmaster logo Thank you for viewing.
