The Jaeger-LeCoultre Master Ultra Thin Moon is an automatic moon-phase watch with a date display. Jaeger-LeCoultre’s US product pages currently identify three stainless-steel versions: blue-dial Q1368480, black-dial Q1368471 and copper-dial Q1368460. The published specifications show the same 39 mm case, 9.3 mm thickness, Calibre 925 and 70-hour power reserve across these references; the clearest distinctions are dial finish and included strap details.
What is the Jaeger-LeCoultre Master Ultra Thin Moon?
It is a watch in Jaeger-LeCoultre’s Master Ultra Thin line, combining hours and minutes with a date and moon-phase display. The US manufacturer pages for the three references below describe automatic watches powered by Jaeger-LeCoultre Calibre 925. Specifications here are manufacturer-listed details, not independent measurements or accuracy tests.

These are the three references surfaced on Jaeger-LeCoultre’s US product pages. Each page lists a 39 mm stainless-steel case, 9.3 mm thickness, automatic Calibre 925, a 70-hour power reserve and 5 bar water resistance.

How should you choose between Q1368480, Q1368471 and Q1368460?
Start with the dial
Q1368480 has a blue sunray-brushed dial; Q1368471 uses black sunray brushing; Q1368460 has a copper grained dial. Choose by color and finish rather than assuming a difference in the core case or movement: the cited pages list the same case dimensions and Calibre 925 with a 70-hour reserve for all three.
Check the exact strap and buckle
The listed straps differ: black alligator for Q1368480 and Q1368471, brown alligator for Q1368460. The Q1368471 and Q1368460 pages explicitly list a double-folding steel buckle; the Q1368480 page does not state that buckle detail. For replacement straps, treat 21 mm as a listed lug width—not proof that every 21 mm strap will fit. Confirm the reference and attachment geometry before ordering.

Verify availability and included accessories
The pages identify US-market product references, but that alone does not establish current production, stock, availability in another country or the accessories included in a particular sale. Check the relevant official product page or a Jaeger-LeCoultre boutique for current details.
What do the dimensions and water-resistance rating mean?
For Q1368480, Q1368471 and Q1368460, Jaeger-LeCoultre lists a 39 mm case diameter and 9.3 mm thickness. Each cited page also lists 5 bar water resistance. That rating is a manufacturer specification, not a blanket assurance that the watch is suitable for every water activity; follow Jaeger-LeCoultre’s guidance for the specific reference.
