A replica Villeret moon phase is a counterfeit Blancpain Villeret watch that copies the brand's lunar aperture at 6 o'clock, normally paired with a complete calendar. The better builds run a real 59-tooth moon disc on a 29.5-day gear ratio. Cheaper builds hide a 24-hour day and night wheel behind the same window, so the moon is wrong twice a day.
What is the Blancpain Villeret moon phase?
Villeret takes its name from the Swiss village where Blancpain was founded in 1735. Moon phase models in that line combine a small aperture at 6 o'clock with day, date, and month displays across the dial. The moon advances in small daily steps and completes a full cycle in about 29 days, 12 hours, and 44 minutes.
How does the moon phase mechanism work?
A correct moon phase runs from a 59-tooth wheel that advances one tooth per day, returning to its start after 59 days, or two lunar months. Blancpain's own calibers use a finer ratio than the simple 59-tooth version, which is why genuine examples stay accurate for decades. The test for any watch: the disc must creep forward each day, not flip between sun and moon.
How to spot a faked moon phase aperture
- Look at the window twice, 24 hours apart. A moving crescent is real; an identical disc is a day and night wheel.
- Check that the crescent grows and shrinks in a smooth arc rather than jumping from full to new.
- Inspect the aperture edge. Sharp, polished bevels suggest a machined dial; rough stamping and paint bleed suggest a low tier build.
- Confirm the calendar hands and the moon disc stay in sync. Skewed alignment points to a weak module.
Which movements appear in replica Villeret moon phase watches?
Most Chinese builds use a Seagull or Hangzhou automatic base with a bolt-on calendar module. Higher tiers use a cloned automatic with a dedicated moon phase gear train and a decorated rotor. The module is where quality drops: thin stamped plates, weak jumper springs, and date wheels that skip under light pressure.
What does a replica Villeret moon phase cost?
- Entry tier, roughly $60 to $120: quartz or basic automatic with a decorative day and night disc.
- Mid tier, roughly $150 to $300: automatic with a working 59-tooth moon disc and complete calendar.
- Top tier, $400 and up: cloned movement, sapphire crystal, closer case profile and dial printing.
What are the legal and practical risks?
Selling or importing counterfeit watches is illegal in the United States under the Trademark Counterfeiting Act of 1984, and customs seizures are routine. Resale value is zero and no manufacturer warranty applies. Authorized service centers will refuse the watch, so any repair falls to independent watchmakers using non-original parts.
Frequently asked questions
Does a replica Villeret moon phase track the real lunar cycle?
Only if it uses a true 59-tooth moon disc. Mid and top tier builds track within a day or two over a month; entry builds with a day and night wheel do not track the moon at all.
Are the complete calendar subdials functional?
On mid tier and up, day, date, and month pointers usually work, though month changes may need manual correction at short months. On entry builds, the pointers are often fixed or move with the crown.
Is the moon phase the hardest part to replicate?
Yes. The gear ratio, the jumper spring tension, and the dial aperture all have to line up, which is why the moon window is the first place a replica reveals itself under close inspection.
