The Bomber Command Clasp is granted to the aircrew of Bomber Command who served for at least 60 days, or completed a tour of operations, on a Bomber Command operational unit and flew at least one operational sortie on a Bomber Command operational unit from the 3 September 1939 to the 8 May 1945 inclusive. This applies to servicemen after they have met the minimum qualification for the 1939-45 Star, which in many cases, though not exclusively, is 60 days.
