What is the split between your Verbal and Quant scores? Is one stronger than the other? What was your college GPA? The answers to those questions will actually play an important role in your decision.
If you're asking for me to draw a line in the sand based on all I know, I would say do not submit the score. By the nature of your question alone, you too are admitting that the GMAT is not going to be a strength in your application and could potentially be a slight weakness or question mark in your application. A 690 is still a great score but given the sheer level of competitiveness this year and likely the one expected near year, you may be best not leaving that to chance.
Would you consider retaking the exam? What have you got to lose?
