Hi there! I have an unusual, never worn, OEM Omega strap for Dynamic. I believe that it is OEM, anyway! It came with a watch I bought, but I prefer to wear mine on a steel bracelet. Hoping to find this one a nice home! The color is sort of a buff, the material seems like leather, but could be Corfam. PRICE: $79 USD - net to me, PayPal friends/family, bank transfer or old-timey check - includes domestic, insured shipping; international at cost - no returns
