Genuine deployant buckle for 20mm straps. Used once for about 2 hours, just doesn't work with my wrist. I'll also throw in a non-Omega strap in brown from Timepiece Republic (again, used just that once so in perfect condition) and a Hirsch Leonardo curved end deployant strap in blue (not pictured) I'm looking for $300 US including express, registered shipping worldwide. Payment by Paypal or wire transfer accepted. Happy to meet face to face for cash with people in Sydney.
