looking for any information

I recently picked up an Omega at auction. everything about it says authentic(maybe a redial). It has a full auto 19 Jewel 471 Cal Movement, and the case looks right, but has a ref (527702) that doesn't show up in any research I have done. And though the movement seems most commonly found in Seamasters, this watch is labeled only 'Automatic'. I can't find anything like this anywhere so any help getting more details on this would be greatly appreciated.

I will get a better picture of the dial. It's not damaged, it is Mother of Pearl - another weird thing.
