Short answer
Vacheron Constantin does not list a watch called Pontes Duo Moon Phase in its 2025 catalog. The name appears on replica storefronts. Official Vacheron Constantin moon phase models in 2025 sit in the Patrimony and Traditionnelle lines. The Patrimony Moon Phase Retrograde Date uses calibre 2460 R31L. The Traditionnelle Complete Calendar uses calibre 2460 QCL. Case sizes run from 41 mm to 42.5 mm. A replica sold under the "Pontes Duo Moon Phase" name copies the dial layout, not the movement.
How Much Does a Replica Vacheron Constantin Pontes Duo Moon Phase Cost?
What the replica name points to
Listings for a "Pontes Duo Moon Phase" show two subdials: a moon disc at 6 o'clock and a date or second time zone at 3 or 9 o'clock. The moon disc shows two moons on a dark blue field with stars. Real Vacheron Constantin moon discs use a 135 tooth wheel and advance once per 29.53 days. Many replicas print one moon and rotate the disc once per 24 hours. That is a day and night indicator, not a moon phase. Ask the seller for a video of the disc across 48 hours. A real moon disc moves about 1.2 degrees per day.

Movement choices in the replica market
- Miyota 9015 with a bolt on moon module. 28,800 vph. 42 hour power reserve.
- Seagull ST21 or ST18 base with a date wheel and printed moon disc.
- Chinese 2813 with a 24 hour disc sold as moon phase. Lowest cost. Highest error.
- Claimed "clone 2460" builds. Few exist. Ask for a photo of the balance and the rotor engraving.
Points to check before you pay
- Moon disc period. 29.5 days is correct. 24 hours is wrong.
- Disc color. Dark blue with gold or silver moons. Flat white discs are wrong.
- Subdial spacing. Vacheron Constantin sets the moon aperture below center. Many replicas sit it too high.
- Date font. Serif numerals. Cheaper builds use block fonts.
- Case thickness. Real Patrimony Moon Phase is 9.7 mm thick. Replicas run 12 mm to 14 mm.
- Water resistance. Sellers list 30 m. ISO 22810 test data is absent.
- Crystal. Sapphire on top. Mineral on the caseback is a cost cut.
Price bands
Replica moon phase watches list from $120 to $900. Under $200 buys a 2813 with a 24 hour disc. $250 to $450 buys a Miyota 9015 with a 29.5 day module. Above $600 buys a custom case, anti reflective sapphire, and decorated bridges. No replica matches the finishing of a Vacheron Constantin calibre 2460. Gold content differs. A real case is 18k white gold or 18k 5N rose gold. Replica cases are 316L steel with plating.

Returns and service
Ask for a 7 day return window and a tracking number. Replica moon phase modules fail at the jumper spring. Parts are scarce. A local watchmaker may refuse the job. Budget $60 to $120 for a service if you find one who accepts it.
