The fake Grand Complication sold under the catalog code 720.025 is a Chinese-made replica of a multi-complication dress watch, and in most listings only part of the display works: the chronograph and moonphase run, while the perpetual-calendar and minute-repeater details are cosmetic. Expect a 40 to 42 mm case, a 7750-based automatic movement, sapphire or mineral glass, and a price between $250 and $600 depending on the tier.
What does the 720.025 code actually identify?
Replica catalogs use numeric codes such as 720.025 to track one build: case finish, dial color, and movement option. The same code can mean slightly different watches from one seller to the next. Treat the number as a listing ID, not a factory guarantee.
Which complications work on the 720.025?
A true grand complication combines at least three functions beyond basic timekeeping, usually a perpetual calendar, a chronograph, and a minute repeater. Replicas at this price point rarely deliver all three in working form.
- Chronograph: normally functional, driven by the base 7750 layout.
- Moonphase: usually a rotating disc on a 29.5-day or 24-hour gear, visible and moving.
- Perpetual calendar: typically a day, date, month, and leap-year display that needs resetting with pushers or a corrector tool; true leap-year logic is rare.
- Minute repeater: almost always decorative on 720.025 builds. Ask for a video with sound before you believe otherwise.
- Tourbillon: when listed, it is often an open-heart balance wheel rather than a real tourbillon cage.
How much should a 720.025 replica cost?
Pricing tracks the dial work and the movement, not the number of printed subdials. Three broad tiers show up in the market.
- Entry, $120 to $250: quartz or basic automatic, printed subdials, no working calendar.
- Mid, $250 to $450: 7750-based chronograph, working moonphase, cosmetic calendar.
- Top, $450 to $800: decorated movement, clean dial printing, functional date and month, better case finishing.
Anything above that range should come with movement photos and a video of every function running.
How do you check a 720.025 before paying?
- Request a video showing each pusher, subdial, and the moonphase disc in motion.
- Ask for a clear photo of the movement with the caseback removed.
- Confirm case diameter, thickness, and lug width against the original specification.
- Check the return window and whether water resistance is tested or just claimed.
- Pay with a method that allows a chargeback.
What movement is inside the 720.025?
Most builds use a Chinese clone of the Valjoux 7750, sometimes fitted with a calendar module. That module adds thickness and is the part that fails first. A watchmaker can service the base movement, but replacement modules are hard to source.
Is a 720.025 replica risky to buy?
Replicas ship without a manufacturer warranty, and customs in the US and EU can seize counterfeit goods. Water resistance claims are frequently untested. Plan for no service support and budget accordingly.
Quick answers
Does the minute repeater on a 720.025 chime?
Rarely. Working repeaters cost far more than this build, so treat any chime claim as unproven until you hear a recording.
Is the perpetual calendar real?
No in most cases. The display advances with the date, but it will not handle 30-day months or leap years on its own.
Can a local jeweler service it?
Some can service the base movement. Few will touch the calendar module or source parts for it.
