Hello, mr. Rupert.
I use an external micropower oscillator LTC6906 of Linear. Please read its datasheet.
It uses an external resistor that determines an output frequency. If you use 217Kohm, 1% tolerance resistor (with Rset tied to ground) you get the frequency range of 458.72KHz - 462.96KHz. It's cheap and consume negligible current (about 40uA at 460.8KHz).
