Enthusiast Explains Escapement Geometry for 45 Minutes; Basil Keene Simply Checks His Own Watch and Leaves

A forty-five-minute explanation of escapement geometry was delivered on Tuesday evening to a room that lost eleven of its twenty-six attendees before the roller table was mentioned.

Ovid Cantrell had prepared slides. He had drawn the pallet stone at four times scale, annotated the lock at 1.2 degrees, the drop, the impulse face, the lift angle of 21 degrees on a movement he specified twice. He gave the group two rate figures to hold in mind: 28,800 vibrations per hour against 18,000, and what each does to the beat error when the stud is moved a fraction. He had measured the fraction.

"He brought a protractor," said one attendee who stayed, in the tone people use about a weapon.

Basil Keene, who runs the collecting group across town and shares roughly half this one's members, did not speak during the presentation. He sat at the back with his arms folded. At minute forty-five he raised his left wrist, held it there long enough for the gesture to be read by the entire front row, stood, and walked out. Four attendees checked their own watches within thirty seconds. Two of them left with him. They were due at his.

Inez Bellamy, who left this group in protest several years ago and has attended every meeting since, rated the lecture third-best she has heard, below the seminar on the Co-Axial escape and above the evening someone explained a Carbon Core Guard to people who had not asked. "Nobody disputed a single number," she said. "That was the problem. Disputing a number is how you get your turn."

A newcomer in his second meeting stayed through the exit and said he followed all of it. He had not. The first term he pretended to understand was draw, he nodded at draw, then at recoil, then at the safety action, and by the pallet stone he was nodding at everything, which is the beginner's equivalent of a power reserve reading empty. When Mr. Cantrell restarted from the escape wheel for the three people still seated, the newcomer stayed. Leaving would have required admitting the nod.

The diagram was photographed twice before the room emptied. One copy reached Silas Tilling's backchannel within the hour, where three separate corrections were posted to the lock angle, none of them matching, and a fourth member asked whether the whole argument would be settled by timing the watch face-down. Mr. Tilling has not commented. He rarely needs to.

Mr. Cantrell, asked afterward whether he had noticed Mr. Keene's departure, said he had, and that he had slowed down to accommodate it.

Mr. Keene's group meets the same hour, across town. He was not making a point; he was running late to his own meeting, where he has since begun a series on mainspring set. Nobody in this room found that comforting.

A watch group recognizes exactly two forms of argument: a rate chart, and someone getting up.
