Omega 2577-7 watch hands

Hi, I have an Omega Seamaster 2577-7 SC calibre 342 dating from the 1950’s. All is fine with the automatic movement and the face is original. Unfortunately the crystal cracked and hands lost at some point. The crystal has been replaced, but I now need to find either some original hands or sympathetic replacements to complete the watch. I should be grateful if anyone can recommend a supplier. Many thanks!
