The Louis Moinet Moon Tech (reference LM-111.20.01) is an 11-piece limited edition with an unusual moon display: two lunar meteorites sit on a domed central disc, while a piece of Apollo 11-flown Kapton serves as the phase indicator, according to the maker. The brand lists an automatic movement, a 40.7 mm Grade 5 titanium case and 30 m water resistance. Louis Moinet currently marks the model sold out; a retailer listing offers enquiry or backorder details, so present availability is unclear.

What is the Louis Moinet Moon Tech?

Moon Tech is Louis Moinet reference LM-111.20.01, a watch the brand says was produced in a limited edition of 11. Its defining feature is a moon-phase display built around unusual materials rather than a conventional printed or cutout moon disc. The specifications and material descriptions below are the manufacturer’s published claims; they have not been independently authenticated or tested here.

How does its moon display work?

Louis Moinet describes a domed disc at the centre of the dial carrying two lunar meteorites from separate rocks. The stones represent the full and new moon. An index at 3 o’clock indicates the phase, and the manufacturer says that index is made from a fragment of Kapton flown on Apollo 11.

The company says the Kapton fragment travelled from Earth to the Moon and back aboard Apollo 11. That is a provenance claim by the maker, not an independently verified finding. The available product information does not explain the mechanism’s exact cycle or how the display advances, so the one-day-in-122-years figure should be understood as a manufacturer-stated performance claim, not a demonstrated result.

What materials are used in the dial and case?

Louis Moinet describes the dial as a silicon wafer engraved with microelectronic circuits. The case is listed as Grade 5 titanium. Together with the two lunar meteorites and the stated Apollo 11 Kapton, these materials give the watch its distinctive technical and space-related story. The product description establishes what the brand says the materials are; it does not provide independent authentication or provenance documentation.

Is the Moon Tech still available?

Louis Moinet’s official product page marks the watch sold out. A Jura Watches listing shows enquiry or backorder details and a displayed price of £30,500; that information is retailer-reported and may change. Neither page establishes current dealer inventory, a confirmed authorized resale offer or a current market-clearing price. Treat any availability or price as something to verify directly before making a decision.

What should you check before buying or replacing the strap?

Because the edition is limited and the maker says it is sold out, ask for current availability and clear documentation for the specific watch being offered. For the meteorites and Kapton in particular, distinguish the brand’s published material story from documentation that accompanies an individual sale.

Louis Moinet lists a 20 mm strap width, which can help when searching for a replacement. Width alone does not establish that an aftermarket strap’s end shape or clasp will fit the case. Confirm fit and clasp compatibility before ordering.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
