I am using TXC 7B 16.0 mghz crystal for my design. I just received photo proofs from my PCB assembly house and it appears they soldered this crystal 180.0 degrees reversed.

No, the polarity does not matter.

Crystals do not have a polarity.

Watch out with Crystal oscillators in a similar housing though (also 4 pins) as their polarity does matter.

But since this is a crystal only (no oscillator) polarity does not matter. It will work mounted either way. I speak from experience with similar crystals from the same manufacturer.
