If you are shopping for a replica Rendez-Vous Moonphase 2208420, the moon aperture is the element to judge first. It is the focal point of the dial and the hardest thing for a factory to reproduce well. Check the moon disc before anything else: the moon face should be crisp and centered in the window, the star field should be printed sharply rather than smudged, and the disc should sit flush with the dial surface instead of floating above it or dropping below it. A build that gets the case and strap right but fumbles the moon window will never read correctly on the wrist, because the eye travels straight to that opening.

What to check on a replica Rendez-Vous Moonphase 2208420

The moon disc and aperture

  • Moon face detail: look for a defined profile with shading, not a flat yellow blob.
  • Star field: individual stars should be distinct; a hazy smear means low print resolution.
  • Aperture edge: the cut should be clean and even, with no burrs or uneven paint at the rim.
  • Alignment: at the current phase, the moon should be centered under the window rather than clipped by one side.
  • Advance check: confirm the disc moves forward when the phase is adjusted. A stuck disc is a common fault on budget builds.

Dial material and finishing

  • Mother-of-pearl should show genuine depth and shifting color. Printed imitation shell looks flat under raking light.
  • Guilloche or sunray patterns should radiate cleanly from the center, with no tool marks or visible stepping.
  • Applied numerals should sit level and cast a small shadow. Printed numerals are a step down on this reference.
  • Hands should be polished on the bevels and free of tool chatter at the tips.

Case, bezel, and crown

  • Case diameter and lug curve should suit a smaller wrist. This is a dress watch, so proportion matters more than presence.
  • Bezel finishing should be consistent all the way around. Uneven polish or a wavy bevel is a giveaway.
  • If the variant is diamond set, check that stones are the same size, sit at the same height, and show no glue residue.
  • The crown should turn with light resistance and seat flush against the case, with no gap.
  • Caseback engraving should have crisp, deep lettering and correct spelling.

Movement

  • An automatic movement is expected at this tier. A quartz movement driving a moonphase is the most common shortcut.
  • Ask how the moon phase is set. Most builds use a recessed pusher or a crown position, and both work if the mechanism is sound.
  • The rotor should spin freely without grinding. Shake the watch near your ear and listen for scraping.
  • Timekeeping should hold within roughly 10 to 20 seconds a day on a mid tier automatic.

Strap and clasp

  • Alligator grain leather should show a fine, irregular scale pattern rather than a repeating stamped print.
  • Stitching should be tight and even, with no loose thread at the lug ends.
  • A deployant clasp should open and close with a firm click and no rattle.

Parameter bands to compare against

  • Case diameter: 34 to 36 mm, consistent with a women's dress reference.
  • Case thickness: 9 to 11 mm, thin enough to slide under a cuff.
  • Lug width: 16 to 18 mm.
  • Crystal: sapphire with an anti reflective coating on the inner face. Mineral glass is a downgrade if it was advertised as sapphire.
  • Water resistance: rated 30 to 50 m. Treat any replica as splash resistant only, regardless of the number printed on the back.
  • Moon phase cycle: about 29.5 days per full rotation.
  • Power reserve: 38 to 70 hours on automatic versions.

Pitfalls that justify a return

  • The moon disc is offset in the aperture or does not advance when adjusted.
  • Mother-of-pearl is printed rather than cut from shell.
  • A quartz movement is sold as automatic.
  • Diamond bezel stones are crooked, uneven in size, or set with visible adhesive.
  • The crystal scratches with a light key test, which indicates mineral glass.
  • Lugs are overpolished to the point that edges feel rounded and soft.
  • The crown does not seat flush, leaving a visible gap against the case.
  • Engraving on the caseback is shallow or misspelled.

FAQ

Does the moon phase actually track on a replica?

On a proper automatic build, yes. The disc advances once per day and completes a cycle in roughly 29.5 days, matching the real synodic month. On quartz builds the display often works as well, but the mechanism feels lighter and the disc can drift out of alignment over months of use.

Is a quartz version a deal breaker?

For a moonphase dress watch, it is a meaningful downgrade. The moon display is a mechanical complication by nature, and the sweep of an automatic movement is part of the look. If the price gap is small, choose the automatic.

When can I safely set the moon phase?

Set it with the watch running and away from the date change window, typically late evening through early morning. Forcing the disc during that period can strip the teeth on the moon wheel. Move the phase forward only, never backward.

How do I confirm the movement is automatic?

Look for a sweeping seconds hand rather than a ticking one, check for a rotor through a display back, and listen for the weight shifting when you tilt the case. A printed rotor plate glued over a quartz module is rare but does exist.

Will a diamond bezel hold up to daily wear?

Stones set with proper prongs hold well. Glue set stones loosen over time, particularly if the watch is worn near water or heat. Inspect the bezel under a loupe before you commit.

Buy the build that gets the moon window and dial material right, and accept small compromises elsewhere. Those two elements carry the look of the reference, and nothing else on the watch compensates for them.
