Hello Gary,
nice to hear, that your clock is running.
I also try different crystals, but none off them are working.
The traces between pin 2/3 of the DS12885 and the crystal are very critical, so i solder mine direct to the socket pins on the botton of the PCB.
Here you have also some guidelines from Maxim: http://www.maximintegrated.com/en/app-notes/index.mvp/id/58
