If there are water oceans, must there be oxygen in the atmosphere?

I am trying to create a planet that either has no oxygen in the air, or it has very little; i.e. not enough to sustain humans without the use of a breathing apparatus. Large portions of the planet (approximately 50-60% of the surface, compared to Earth's ~70%) are covered with oceans, seas, lakes, and other bodies of water, much like those that are found on Earth. The planet has no native life forms, but in all other respects, assume that the planet is like Earth.

Is this scenario scientifically feasible? Or will the presence of large volumes of water inevitably result in some of the oxygen making its way into the atmosphere?
