That sounds like normal crystal aging. See

Subject: [time-nuts] An interesting behavior with my Sulzer 2.5A...
Being the season of thunderstorms and protracted power outages; As my UPS
quit before the power restored, I am reminded of a behavior that I have
always found curious:
When the power fails on my Sulzer 2.5A, for more than a few minutes, the
frequency takes a quick hop lower a few parts in E9. I then get to spend a
couple of days bringing it back on frequency, and find that for the next
several month it begins a very slow climb up in frequency back to where it
was after the short interruption in power.
Any ideas on what is happening?
