Thank you for looking. This is a Calme stainless steel mesh belt. I had planned to attach it to an IWC watch, but I ended up not using it. It is unused. Only the main unit is included; spring bars are not included. This is a wire mesh belt made of high-quality stainless steel. It features a single-action D-buckle with a side button for easy attachment and detachment. It is a stylish stainless steel bracelet that is easy to match with various outfits. Brand: Calme Model Number: SWC-38 Clasp Type: D-clasp Band Material Type: Stainless Steel Band Width: 20 millimeters Band Color: Silver
