Source durations remain fixed. NASA [S01] Record / Apollo Flight Journal [S02] Record
The Apollo 13 record is more interesting than a story about a miraculous fraction of a second. The ground calculated a fifteen-second firing and instructed the crew to shut down at fourteen. Ending early was deliberate: the mission report explains the desire to avoid an overburn that would require an undesirable correction.
NASA [S01] Record / Apollo Flight Journal [S02] Record
On a sixty-second chronograph dial, fourteen seconds occupy 84 degrees. The moving hand below illustrates that arithmetic. It is not footage of the actual watch, an estimate of its accuracy, or proof that a particular fraction of a second separated survival from disaster.

One kilometer gives km/h; one mile gives mph. No known distance means no speed estimate.
Calculated function. Lee Bailham / Eric M. Jones, Apollo Lunar Surface Journal [S16] Retrospective
Its external tachymeter made a familiar operation convenient: time one known distance, then convert the duration into an hourly rate. Thirty seconds over one kilometer gives 120 kilometers per hour. Time one mile instead and the same number means miles per hour. The measured distance supplies the unit.
Omega / Swatch Group [S10] Manufacturer / Lee Bailham / Eric M. Jones, Apollo Lunar Surface Journal [S16] Retrospective
This is a small lesson in what an instrument can and cannot know. A duration alone does not supply a distance. An engine burn lasting fourteen seconds therefore cannot be turned into spacecraft speed simply by reading a tachymeter.

Watchfid [S04] Retrospective
James Ragan's later account describes four proposals, one of them for a non-wristwatch. NASA acquired three watches from each of the three remaining suppliers, with different units used for evaluation, testing, and backup. Those roles do not form nine interchangeable observations in a controlled reliability experiment.
Time+Tide / James H. Ragan [S03] Firsthand account
Temperature, pressure, acceleration, vibration, humidity, oxygen, shock, and sound imposed different demands. The eleven cards preserve the units and exposure conditions in one retrospective protocol summary. They deliberately do not turn degrees, g-forces, and decibels into a common ranking.
Watchfid [S04] Retrospective
Only the Speedmaster qualified in this account. Qualification did not mean it emerged entirely unaffected: the reconstruction also reports changes in rate and luminous material. A tested instrument can be useful without being invulnerable.
Time+Tide / James H. Ragan [S03] Firsthand account / Watchfid [S04] Retrospective
The protocol itself has a source boundary. An archived 2009 Omega account gives 71 degrees Celsius rather than 70, a different humidity range, and a 333-second acceleration ramp without Watchfid's 16 g stage. We retain Watchfid's summary rather than manufacture a composite test. The original laboratory reports were not obtained to resolve these differences.

With primary guidance powered down, Haise controlled pitch and Lovell roll; the abort guidance system maintained yaw. Swigert called engine start and stop. The fourteen-second firing at ten percent thrust belonged to a larger sequence of alignment, ignition, assessment, and adjustment.
NASA [S01] Record / Apollo Flight Journal [S02] Record
After the main firing, the transcript records a 7.4 feet-per-second readback and an instruction to trim to 7.6. A display offset is discussed as well. These are operational readbacks, not a clean series of measured total velocity changes from which we can reconstruct an independent trajectory.
Apollo Flight Journal [S02] Record
Omega identifies Speedmasters as the timing instruments. The cited report paragraph does not identify a brand, reference, serial number, or wrist. Swigert calling the timing does not establish which particular watch was used. The defensible conclusion concerns a usable backup function within practiced coordination.

This is a visual study of the supplied exterior model, not a servicing sequence. Its 62 selectable units are geometric groups, not an authenticated bill of physical parts. It does not contain a verified mainspring, escapement, or complete calibre-specific movement. We do not add plausible gears to conceal that absence.
In the classic three-register layout, the long central hand belongs to the chronograph; ordinary running seconds have their own register. A stopped chronograph hand does not mean that the watch has stopped keeping time. A chronograph is a function. A chronometer qualification is a different claim.

Omega [S05] Manufacturer / Omega [S06] Manufacturer
Omega's recreation of the 321 drew on tomography of a Moon-flown movement associated with Gene Cernan's Apollo 17 watch. That reconstruction project and the development of the 3861 show two different approaches to continuity: recover a historical design, or preserve recognizable features while changing the engineering.
Omega / Swatch Group [S08] Manufacturer / Omega / Swatch Group [S12] Manufacturer
The 3861 appeared in anniversary models in 2019; the regular Moonwatch adopted it with Master Chronometer certification in 2021. The two current reference configurations compared here share a fifty-hour listed reserve and three-hertz nominal frequency, but their listed thickness and approximate bracelet weight differ.
Omega [S05] Manufacturer / Omega [S06] Manufacturer / Omega / Swatch Group [S09] Manufacturer
Their dimensions are attached to full reference numbers, not to the entire family or the model on this page. The sapphire configuration's listed thickness is 0.36 millimeters lower and its listed weight four grams higher. Those differences do not isolate the effect of the crystal alone.

These are conversions of modern specifications, not counted Apollo observations.

METAS describes finished-watch certification across positions, temperatures, states of wind, and magnetic exposure, as well as reserve and water resistance. Omega states zero to plus five seconds per day for these two products. The wider N001 framework permits category-dependent maxima of plus five, six, or seven seconds; five is not a universal ceiling for every METAS watch. These are mean-rate criteria, not a uniform rate during every second of ownership.
Omega [S05] Manufacturer / Omega [S06] Manufacturer / METAS [S07] Certification authority / METAS [S24] Certification authority
As a dimensional illustration only, five seconds gained uniformly over a day would accumulate to about 0.81 milliseconds in fourteen seconds. That calculation is not the Apollo watch's error. It leaves out button operation, reading, start-stop judgment, and changing rates. Precision in the arithmetic does not make the historical inference available.

What the measurements do not contain.
A specification can describe a rated reserve. A mission record can establish a firing duration. An announced edition can identify a production ceiling. Each becomes more useful when we keep its boundary close.
For this watch, another piece of provenance is personal. I bought it with part of my grandmother's inheritance; I did not inherit the watch itself. Its mechanism explains how an interval is measured. That connection belongs to a different kind of record.
If the pieces are still on the table, the Rebuild control returns them to their exact rest poses.

The historical visualization uses proportional calendar time. Bands preserve the supplied month, year, or range instead of pretending that an imprecise date was a precise January 1 observation. The watch-face chapter map encodes reading order, not historical time.
Tachymeter values, dial angles, nominal beat counts, unit conversions, and the uniform-rate example are calculated. They do not create new observations or improve the precision of their inputs.
The commercial section separates edition caps, allocation, uncapped supply policy, and reported sales. Annual production, price histories, and resale returns remain unestimated.
