You need a better picture, I can only read parts of it.
In any case, what I can tell you is it's a series cut surface mount crystal. There is no internal oscillator circuitry, it is not a oscillator by it's self. The markings on the top are usually the running frequency, but in this case it does not look to be so.
Try getting a different angle for your picture. Try moving light around. Some times it helps to have two lights. Also more pictures of the rest of the circuit can help identify the running frequency, based of the intended design. IE, the IC that it's attached to most likely has a range of frequency at which it will run from. And some common devices almost always run from a specific frequency.
