Hi I looking into trying to checking the frequency of the oscillator in watches that use crystals around 32kHz without opening the case its the front end where I have a problem with any ideas.

Yes you correct its for digital watches in plastic cases one of my mates work with watches and want to check the frequency of the oscillator without opening the case. I said I think about it and I believe the problems are in 2 parts.
1 how pick up the oscillator frequency .
2 display results.
I know I can design a frequency counter and display the results in the required format using a micro eg. a pic but the front ends the problem.
Any ideas

No the watches have digital display its not going to easy but if can pick up the frequency the rest is no problem
