EULIT Perlon strap, black, 20mm. (Looks gray depending on the light, but it's black) Rare NATO strap type. This item is 6499 yen on Rakuten's Chronoworld. (An example of it being attached to an Omega Speedmaster is shown) I only attached it to a watch once. It's in very good condition as shown in the photos. Because it's black, it's versatile and should match various wristwatches. Thank you. - Morellato - Hirsch - CASSIS - BAMBI - Rochet - Di-Modell - Fluco - Delugs - Barton Watch Bands - Hadley-Roma
