Vintage Omega 111.0107

Hello all,

I am new to vintage watches, and recently came across this piece. The seller said it was a ref 111.0107, and may I ask if there is anything not right with this watch? Such as redial or a frankenwatch? I haven’t seen a lot of blue dials on this model online.

Thanks for the help!
