The larger mass
The escapement: it sets the character
The escapement holds the train, releases one tooth at a time, and hands the oscillator an impulse. Which escapement a watch has decides how it feels, how it sounds, and how it wears. It does not decide the rate.
The smaller mass
Leave with the four cells filled
This bench's proposition, in one line: the escapement sets the character, the oscillator sets the rate. Time a watch properly — rate, amplitude and beat error at a stated lift angle — and the regulate-or-service decision follows from the card.

How these papers are kept
The clock here is an issue, not a feed. Issue 01 is dated and its proposition is stated above. Objects are definitions and carry no issue number, because a definition does not change. Notes carry the issue they appeared in and the date they were written, because a note is a judgement made on a day.
Every page carries the same four-cell card, and the fourth cell is the lift angle. It is not a reading; it is the disclosure that makes the other three usable. A rate, an amplitude and a beat error with no angle are three numbers about an unknown watch.
Set this page down when you can say which escapement you have and read the four cells off your own watch.
