David!
I was just taking a look at your Nixie watch diagram, what is the function
on the resistor R11 = 510K on the Crystal circuit of the pic.
For getting better readings on the output oscillator?
Thanks a lot.

Hello Bill,
Thanks a lot for your answer and your knoledge,
I will do a chart with different capacitors values and I will see how the time
The DS3232 has an internal crystal, with periodic temperature compensation
(every 100 seconds). There are also non-volatile trim registers that allow
you to fine-tune the trimming even further, though I have not needed to do
that.
You wont be able to use a scope to fine-tune the crystal oscilla
Hello David!
that's awesome, I really like the idea, I just bought an oscilloscope but a
really cheap one, the only one I could affort.
I will try make some change's on the watch to catch a Via to connect the
oscilloscope to it and take a good look to the frecuencia to try to get
that 32.768

My Nixie watches have a variable 5-3
My Nixie watches have a variable 5-30pF capacitor on the crystal so that I
can adjust the oscillator to exactly 32768 Hz. You could use a different
value depending on your crystal characteristics. I use an old Hewlett
Packard universal frequency counter, running in time period averaging mode,
