At one stage, I had a lot of quality problems with these small cylindrical 32.768 kHz crystals for a project. The test below helped to identify possible suspect crystals. I applied a 1 Vp-p pulse train (at 1/2 the crystal frequency) as shown through a 1 pF capacitor over the crystal and monitored the response with a x100 scope probe. (...)
During testing give more dead time. So that u can ensure no shoot through. After rectifier did u put filter capacitor? That is mandatory. Check the pulse pattern. - - - Updated - - - post ur ckt. so that we can suggest u better.
