I ran a watch on a basic timegrapher and got +6 s/d, 245 degrees amplitude and 0.8 ms beat error, dial up, about an hour after winding. Is this good, bad or normal? I don't want to send it for service on a single reading.
Reply scope: address the opening question, explain the supporting record or reasoning, and state the limit of the answer.
First identify the caliber, lift-angle setting, winding state and measurement position. Without those fields, the rate, amplitude and beat-error values lack enough context for a useful comparison.
Can the same settings and winding state be used for several positions? Record each position separately rather than combining measurements taken under different conditions.
Amplitude depends on the movement and measurement setup. Compare it with appropriate specifications and a qualified watchmaker’s assessment; a universal pass/fail threshold would be misleading.
The lift angle must match the movement specification for the amplitude reading to be meaningful. If it is unknown, label amplitude as provisional instead of accepting the instrument default.
A useful table has columns for date, position, winding state, lift angle, rate, amplitude and beat error. Keep the full recording so settings and stability can be checked.
The reported numbers alone do not establish damage or the need for service. Confirm the setup, collect comparable readings and ask a watchmaker to assess a concerning or changing pattern.
Clarification for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: the point beginning “First identify the caliber, lift-angle setting, winding…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.
Method note for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: use “First identify the caliber, lift-angle setting, winding…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Keep the stated question separate from any broader claim.
Limit of the answer in “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: “First identify the caliber, lift-angle setting, winding…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: scope. Keep the stated question separate from any broader claim.
Correction note for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: retain the wording beginning “First identify the caliber, lift-angle setting, winding…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.
Summary draft for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: the answer addresses “First identify the caliber, lift-angle setting, winding…”; the related point is “Without those fields, the rate, amplitude and beat-error values lack…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: scope. Keep the stated question separate from any broader claim.

Reader check for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: distinguish the discussion point “First identify the caliber, lift-angle setting, winding…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: scope. Keep the stated question separate from any broader claim.
