Professor Bell arrived at the same minute every evening. Former students described him as a man governed by the sky. His donated watch, however, ran eight minutes fast even after a fresh battery was fitted.
Apprentice Eda found a note in the case: leave it ahead; stairs take longer now. Bell had adjusted his routine as his mobility changed, using the wrong displayed time to reach the observatory at the right actual time. His punctuality depended on accommodation rather than on refusing to age.
Eda checked the workshop receipt to confirm that the watchmaker had been asked to preserve the setting. The receipt made an intentional choice distinguishable from a faulty mechanism. She wrote the exhibition label around that choice, with the family's permission.
Visitors still smiled at the watch, but some recognized their own small arrangements for managing difficult journeys. Eda stopped calling them tricks. Bell's note was an instruction to make a tool serve its owner, not a demand that the owner match the tool. His students had remembered the arrival and overlooked everything he did to make it possible.
