The case is 40mm pink gold.
It runs the 899/1, an automatic movement.
Catalogued dial colour: grey.
Sourced from scratch 2026-08-24 -- no live jaeger-lecoultre.com page found (absent from the current sitemap). WatchBase and Hourstriker's watch database independently agree: Pink Gold, 40.00mm round case, self-winding Calibre 899/1, slate-grey sunburst dial, a 'Boutique Edition' of the 40mm Date sub-line (sibling to Q1282510). Introduced 2015 per WatchBase. Hourstriker's own page mislabels the model 'Master Grande Ultra Thin' in its title, inconsistent with WatchBase and with this reference's own modelFamily elsewhere in this catalog; treated as a Hourstriker naming slip, not recorded as a fact.

How do I check a Jaeger-LeCoultre Q128255J with Watch Safe?
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
