I recently purchased an omega sea master deville automatic wristwatch. I am trying to find the the original signed omega crown . The case number is 166020. Can anyone help me find the part number ( with female stem) or at least the specs so I can hunt around the internet to see if I can locate one. Any help is greatly appreciated. Best. Ed
