Short Answer
The phrase "fake rendez-vous back of the moon" comes from Apollo landing conspiracy talk, not from watchmaking. The lunar module and the command module did dock behind the Moon, out of radio contact with Earth, and that gap in the radio record is what the staged-landing claim leans on. If you found this page while shopping for a moon-phase or dark-side chronograph, the space debate is a distraction. Authentication runs on reference numbers, measurements, and movement inspection.
Prerequisites
- The full reference number from the seller, in writing.
- A gram scale and a pair of digital calipers.
- A 10x jeweler's loupe.
- Photos of the caseback, clasp, and movement.
How to Vet a Moon-Theme Watch
- Ask the seller for the full reference number and the production year, and keep the written reply.
- Measure the case diameter and thickness with calipers and compare both figures to the published spec.
- Weigh the watch on a gram scale and compare the total to the known weight for that reference.
- Study the caseback engraving with the loupe and check that the lettering has crisp edges and even depth.
- Check the date window position against the subdials and confirm the spacing matches the original layout.
- Start the chronograph and time the sweep hand against a reference clock for a full 60 seconds.
- Press the reset pusher and confirm the hand returns to zero in one motion with no drift.
- Inspect the clasp stamping and the end-link fit against the case.
- Photograph the balance wheel and the rotor through the display back.
- Request the service record or the movement serial number.
- Compare the asking price to the current secondary market range for that reference.
- Walk away if the seller refuses an in-person inspection.
Red Flags
- A price far below the market range for a complete watch.
- Stock photos used in place of images of the actual piece.
- A seller who will not give a reference number before payment.
- Subdials that sit at the wrong height or crowd the date window.
- Caseback text with rounded edges, shallow cuts, or spelling errors.
- A chronograph hand that creeps or bounces on reset.
Why the Rendezvous Story Does Not Help You
A spaceflight claim tells you nothing about the object in your hand. Counterfeit listings borrow dramatic language, moon imagery, and limited-edition wording to create urgency. Ignore the narrative and work through the checks. Reference numbers, caliper readings, gram weights, and movement photos are the only evidence that holds up. If a seller leans on the far-side docking as proof of authenticity or rarity, treat that as a signal to slow down.
