路I'd need to check as it's late here but, I fitted a new Omega crown to mine last year and the notes I can see say 42057ST as the part number. Should be the same for yours but, like I say, I'd need to check. I know yours is an auto and mine is a manual wind but should make no difference in this case as the 552 (I suppose in yours) and 601 share much of their design. I can get them for about 拢25.
Looks great on the perlon馃憤
