Useful Mnemonic

One of the things we are expected to memorize in watchmaking school are the 8 factors that affect the isochronism of a watch. With the help of a 'scrabble cheat' program on the internet, I came up with a very helpful mnemonic to remember these factors. Just remember to 'preempt friction'

P - Poise of hairspring
R - Regulating pins
E - Escapement
E - External Influence
M - Magnetism
P - Poise of balance
T - Temperature
