Methinks its supposed to be one or the other. Me too - especially as it says "caps not pop with watch cry..." However, given that the 2 crystals differ so vastly in fequency, could it be possible that each would be effectively "invisible" when the oscillator was running at the other's frequency - so this could actually be a cunning way to have a "dual-speed" clock...? |
