How a machine reads this record

Documentation of the published retrieval path.

Reference documentation · not a request log

Entity → canonical URL → record.json → field → provenance

These are the paths and properties this record actually publishes. Nothing on this panel ran, and no query or answer is depicted.

A consumer that finds value: null receives null. MeasuredWatch does not fill it.

  1. 01Entity

    The record is identified by brand, model and reference, and carries a stable record ID.

    brand.name   "Jaeger-LeCoultre"
    model        "Reverso Tribute Duoface Small Seconds"
    mpn          "Q3988481"
    recordId     "MWR-000338"
  2. 02Canonical

    The canonical page embeds the same document in a <script type="application/ld+json"> tag, server-rendered.

    https://www.measuredwatch.com/watches/jaeger-lecoultre/reverso-tribute-duoface-small-seconds-q3988481
  3. 03Endpoint

    The same document is served standalone. Response headers set by the route:

    GET https://www.measuredwatch.com/watches/jaeger-lecoultre/reverso-tribute-duoface-small-seconds-q3988481/record.json
    Content-Type: application/ld+json; charset=utf-8
    Access-Control-Allow-Origin: *
    Link: <https://www.measuredwatch.com/watches/jaeger-lecoultre/reverso-tribute-duoface-small-seconds-q3988481>; rel="canonical"
  4. 04Field

    Each tracked field is one PropertyValue in additionalProperty, keyed by propertyID. Values are published as the source text; no unit conversion is applied.

    propertyID  "case_material"
    value       "Stainless steel"
  5. 05Provenance

    Provenance travels with the field, not the page.

    measuredwatch:provenance  "published"
    measuredwatch:sourceType  "manufacturer"
    measuredwatch:sourceUrl   "https://www.jaeger-lecoultre.com/us-en/watches/reverso/reverso-tribute/reverso-tribute-duoface-small-seconds-q3988481"
    measuredwatch:checkedAt   "2026-09-15T17:57:21.434+00:00"
  6. 06Unknown

    A field with no supported value is still published, explicitly, so absence is machine-readable.

    propertyID            "diameter"
    value                 null
    measuredwatch:status  "unknown"
