Omega Deville seamaster watch

[murray]

Hi everyone, just joined the forum scene and would like some help. I have just inherited an Omege automatic with seamaster stamped on the back casing and Seamaster Deville on the face. It's in good condition but I cannot find anything about it. Can anyone put a price on it? It has an antique looking 9ct gold bracelet which is not Omega. Where should I look for another bracelet like it, this one is too small for my wrist. Any information would be much appreciated.
