The watch looks very good to me. The case and movement are clean don't appear over polished. The price as you say , is very fair for a 564 in excellent condition. Generally speaking these watches were sold on a band with the buyer picking a band of Omega or after market of their choice.
Here is one of mine on both a crocodile and its original after market band that the watch came with from the dealer.
Remember this model takes
19mm band (kind of nice) and the crown is
supposed to be only semi-hidden on 168.010.
