Escapement Papers — notes and re-checked jobs https://escapement.top/ Dated judgements, checks and disagreements about mechanical watch escapements. Objects are not syndicated: a definition does not change. en 2026-09-16 09:00:00 +0000 How to regulate a watch in six positions, in order https://escapement.top/jobs/regulate-in-six-positions/ https://escapement.top/jobs/regulate-in-six-positions/ 2026-09-16 09:00:00 +0000 Regulating a watch means correcting positions in a fixed order, because each correction moves the others. Here is the order, the target bands, and when to stop. Does my watch need a service, or just a regulation? https://escapement.top/jobs/tell-a-service-from-a-regulation/ https://escapement.top/jobs/tell-a-service-from-a-regulation/ 2026-09-16 09:00:00 +0000 A watch that keeps poor time may need a regulation, a demagnetisation, or a service. The four-cell card decides which, and the amplitude is the deciding cell. How to store a mechanical watch so it still runs well https://escapement.top/jobs/store-a-watch/ https://escapement.top/jobs/store-a-watch/ 2026-09-16 09:00:00 +0000 Storing a mechanical watch is mostly about magnetism, humidity and whether to keep it running. Each has a specific failure it causes and a specific fix. Two timing machines, two default lift angles, one watch https://escapement.top/notes/2026-09-10-lift-angle-disclosure/ https://escapement.top/notes/2026-09-10-lift-angle-disclosure/ 2026-09-10 09:00:00 +0000 Two timing machines with different default lift angles report amplitudes 30 degrees apart on the same watch. Neither is broken. The angle was never set. What in-house means, and the two definitions in use https://escapement.top/notes/2026-09-03-in-house-argument/ https://escapement.top/notes/2026-09-03-in-house-argument/ 2026-09-03 09:00:00 +0000 In-house can mean that a brand made the movement, or that it made most of it and finished the rest. Two definitions are in use and they give different answers. The amplitude trap: a wrong lift angle hides a tired movement https://escapement.top/notes/2026-08-26-amplitude-trap/ https://escapement.top/notes/2026-08-26-amplitude-trap/ 2026-08-26 09:00:00 +0000 A wrong lift angle does not just change the amplitude. It can turn a movement that needs a service into one that looks healthy, which is the costly direction. How to tell whether a hairspring is magnetised, in a minute https://escapement.top/notes/2026-08-15-magnetised-hairspring/ https://escapement.top/notes/2026-08-15-magnetised-hairspring/ 2026-08-15 09:00:00 +0000 A magnetised hairspring makes a watch run fast, sometimes very fast, and it looks completely normal. Here is the check that needs no tools and no case opening. A verge escapement is not an early lever escapement https://escapement.top/notes/2026-08-04-verge-is-not-a-lever/ https://escapement.top/notes/2026-08-04-verge-is-not-a-lever/ 2026-08-04 09:00:00 +0000 Verge and lever escapements are often described as early and late versions of one idea. They are different mechanisms, and the difference matters when dating. What recoil costs in seconds per day, per beat and per year https://escapement.top/notes/2026-07-24-deadbeat-vs-recoil/ https://escapement.top/notes/2026-07-24-deadbeat-vs-recoil/ 2026-07-24 09:00:00 +0000 Recoil in an escapement costs time on every beat. Worked per beat, per day and per year, the cost of a small recoil turns out to be a large number of minutes.
