Hi, Flotul
The best and easier way is to buy quality crystals ... ( from Farnell i.e...).
The second way is to use External DIP oscillators ...
The Third way is to buy a good Freq meter ....
I also think you can get precise 10 Mhz by radio ... ( see Radio ham ...)
You can also correct time every minute with a DCF module !!!
What I usually do is to play with the timer preload value ... fits most of time !!!
One of the electronician's main headache has always been to have home good references ... ( Volt, freq, temp,pressure ...humidity ( LOL ! ) )

IF there is the word "Problem" in your question ...
