I'm working on a project where i try to make a normal clock.Everything is finished and ready except for the main signal coming from the oscillator.
I'm making a relaxation oscillator of course but i'v so many questions...

**FIRST :** About the RC oscillator in general:
i want the clock to be very precise and accurate so is the RC circuit will give me that precision...?
And how about the temperature stability,Will the RC be good in this condition as i know that the resistors are very bad at temp. stability...???
Finally what components should i use in the design,Should i use Op-Amps or MOSFETs or BJTs...? i'm asking here from the power consumption point of view...

**SECOND :** About the Crystal Oscillators
I know that the crystals are very accurate and maintain a very good temp. stability,However is it possible to generate a crystal quartz oscillator without the use of a microcontroller.And if so what is the best configuration that i should use in that design...
And how about the power consumption does the crystal takes more power than the normal RC circuit if they produce the same frequency...

**THIRD :**
Is it possible to make a clock with a good precision with the use of ONE AA battery and last for about 3 months min or i'm dreaming about this...?

I hope i didn't annoy you with that much questions and **Thanks in Advance** :-)
