The watch strap for Agnès b. is 9mm wide at the attachment point. Although the attachment width is 9mm, the shoulder part of the strap is 11mm. How about this for those looking for a replacement strap? There are minor scratches due to use. Although ultrasonic cleaning has been performed for the listing, please refrain from purchasing if you are looking for new quality. Thank you. - Brand: Agnès b. - Color: Silver - Width: Attachment width 9mm, the width of the strap itself is 11mm. Thank you for viewing. Please feel free to ask any questions.
