Hi Ivan, I've just replaced the 32kHz crystal on my CB2 but it's still losing about 2 secs / minute. Could be a problem with the trim caps but my eyesight isn't quite up to playing with them at the moment.
My CR2032 battery (installed new about a week ago) has dropped to 2.8V already so it looks like there is an excessive drain into the AXP209. This could be a problem with my soldering a lead to pin 30 of the AXP. I'll persevere with this for a bit but the idea of fitting a DS1307 module sure is looking attractive. You are right about the 32kHz crystal which doesn't show up on the schematic. I expect that the replacement crystals I bought should be a lot more accurate than appears here. Changing bit 0 of the osc_ctrl_reg (internal/external oscillator) doesn't appears to make any difference.
