Narrative:

How problem arose: inattn to the aircraft. Instead of watching to see if the aircraft turned the correct way, I was busy keeping track of time/fuel. The aircraft turned to an incorrect waypoint and turned north instead down J131 towards deven intersection. When I looked up to check, I was approximately 60 degrees heading to the right. Center called and asked us our routing at the same time. Stronger habit patterns would prevent a recurrence. Supplemental information from acn 238377: over pocket city VOR, aircraft turned 60 degrees right of course. Center called to confirm route. We corrected omega to join J131 to lit. I was busy checking route when this happened.
