Most people who use a crystal for clock work use a 32.768KHz one - they are ten-a-penny, and just as easy (easier - one less step) to divide down to 1Hz.
The thing with a crystal is it doesn't readily oscillate by itself. You use it with an oscillator to regulate and control the frequency. The crystal resonates at the specified frequency, and drags the oscillations of the existing oscillator in to line with it.
You have to have an existing oscillator that is working at roughly the right frequency already.
The simplest oscillators are made from one or more simple logic gates (NOT, or NAND), some resistors, and a capacitor or two.
