De Luca Mk 1 Bracelet Question

Hi All, asking any De Luca Mk 1 owners for your bracelet advise please! I just read this Mk 1 (on left) with small logo caseback so likely a 1988 watch. It was delivered on bracelet but the flanges on the clasp do not attach to the pin (2nd picture). The 3rd picture shows how the flanges should attach to the pin, but they are just resting on top and not attached. Can you please look at your Mk1 bracelet and advise how this connection should work? I am trying to learn if it’s missing a part or if the flanges were just welded to the pin. Sincere thank you! Russ in Dallas, Texas
