Top pick: a rose-gold 3940 super clone with an automatic micro-rotor movement and a correct three-subdial dial layout. That combination is the only one where the price stays defensible. Everything else about this reference is negotiable, but four things decide what a seller can charge: dial geometry, case profile and thickness, movement type, and how the perpetual calendar data is displayed. Price tracks those four factors and almost nothing else.

Why the 3940 Is Expensive to Copy Well
The original is a 36 mm perpetual calendar with a micro-rotor automatic caliber, three recessed subdials, and a moonphase at six o'clock. The reference carries day, date, month, leap year, 24-hour indication, and moonphase in a case that sits thin on the wrist. That layout leaves no room for sloppy alignment. A subdial shifted by half a millimeter is visible from arm's length, and a thick case is the first thing anyone notices on a 36 mm watch.

That is why the market splits so sharply. Cheap builds use a printed dial on a generic case and a quartz or basic automatic movement. Better builds use a stamped or engine-turned dial, a slimmer case, and a decorated automatic movement that at least looks the part through a display back.
Price Bands and What Each One Buys
Prices in this category are quoted in three broad bands. Treat any figure you see as a snapshot, because movement supply and gold plating costs move them.
Entry band (low three figures)
Expect a plated case, a printed dial, and a base automatic or quartz movement. Subdials often sit slightly off-center. The leap year and 24-hour indicators are usually decorative rather than functional. This is the band to avoid if you want the watch to read correctly across a room.
Mid band (mid three figures)
This is where most buyers should shop. You get a properly laid-out dial, a case with correct lugs and a thinner profile, and a decorated automatic movement. Gold plating is heavier and holds up longer. Moonphase and calendar discs usually move, though not always in correct sequence.
Upper band (high three figures and up)
Here you are paying for case finishing, dial printing quality, and a movement with a micro-rotor or a close visual stand-in. Expect correct pusher placement and a functional leap year indicator. Ask for photos before paying at this level.
Parameters That Decide the Price
Dial layout and subdial positions
Check that the subdials sit at three, six, and nine o'clock, that they are recessed rather than flat, and that the hand lengths reach the correct tracks. Printed text should be crisp, not fuzzy at the edges.
Case, lugs, and plating
Ask for the measured diameter and thickness. A 36 mm case with a slim profile is the goal. Lugs should curve and taper, not sit as flat blocks. Plating thickness determines whether the gold tone survives daily wear.
Movement
Ask directly what is inside. A decorated automatic with a rotor or micro-rotor is the standard for mid and upper builds. A quartz movement in this reference is a hard pass at any price above the entry band.
Calendar and moonphase function
Confirm which indicators actually work. On many budget builds the leap year aperture is fixed and the moonphase disc does not cycle. Ask the seller to send a short video of the pushers being used.
Pitfalls to Avoid
- Buying from photos only. Daylight, wrist, and macro shots show different things.
- Accepting a quoted price with no spec sheet. Diameter, thickness, movement type, and plating should be stated in writing.
- Assuming all sellers mean the same thing by "super clone." It is a marketing term, not a grade.
- Paying a deposit through an untraceable method with no order record.
- Ignoring service access. Ask whether the movement can be regulated or replaced later.
Which Build Fits Which Buyer
If you want a dress watch to wear a few times a month and you care about looks over mechanics, the mid band is the right spend. If you want the closest visual match and you will actually use the calendar functions, go upper band and insist on movement details and a functional leap year indicator before you pay. If the budget is fixed at the entry level, buy the best dial and case you can find and accept that the calendar is cosmetic. In every case, get the specification in writing and pay only after you have seen the exact watch, not a stock photo.
