Pendulum Clock Calibration?

Any ideas how to calibrate one of these? This one is gaining at least 10 minutes a day. 8.01 is too long ago for me to remember the relationship between the mass on a pendulum and its period, but that is something that is adjustable here.

(I'm also pondering ways to automate it; right now it needs winding about once a week. But I don't want to modify it significantly...)
