Thank you very much for viewing. This is a watch strap, a fabric nylon NATO strap. It is manufactured using a different method than the typical NATO strap, and offers superior comfort and durability. The color is red spot. The buckle and metal fittings have a hairline finish and are made of stainless steel. Because it uses spring bars, it is also possible to replace the buckle with another. [Specifications] Thickness: 1.2mm, Length: 28cm Compatible brands: Seiko, Rolex, Omega, Hamilton, IWC, and others We will ship within 24 hours of purchase.
