Fake drive 42mm refers to a replica of the Cartier Drive de Cartier in its largest case size, where 42 mm is the width of the cushion-shaped case measured across the dial with the crown left out. That number is the most useful filter in this search, because the Drive line has been offered in several sizes, and a 42 mm listing describes a very different watch on the wrist than the 40 mm three-hand models.
What the 42mm Measurement Covers
Case diameter is taken at the widest point of the case body, crown and pushers excluded. On a cushion case like the Drive, that width sits close to the case length, so the watch reads almost square from above rather than round.
- Diameter: the 42 mm figure. Measured across the case, not the crown.
- Length (lug to lug): often the number that decides whether a watch fits, since it drives how the strap sits over the curve of the wrist.
- Thickness: chronograph versions run deeper than time-only versions, which changes how the watch tucks under a cuff.
- Weight: a steel 42 mm case with a bracelet carries noticeably more heft than a 40 mm piece on leather.
Why the Cushion Case Is Hard to Copy
The Drive case is not a simple round puck with a strap. Its sides curve, its corners soften into a rounded rectangle, and the finishing alternates between brushed surfaces and polished edges. The dial typically carries a textured guilloché pattern, applied Roman numerals, and a rail-track style minute scale. The crown is set with a blue cabochon. Each of those elements is a place where a replica either matches the proportions or does not.
Brands publish official dimensions for their collections, and those published figures are the reference point worth checking before you trust any listing that says 42 mm.
Inspection Checklist for a 42mm Drive Replica
- Measure it yourself. Use calipers or a ruler across the case back if you can, and compare with the stated diameter.
- Check the dial printing. Look at spacing between numerals, alignment of the date window, and whether lettering sits centered under the 12.
- Look at the crown. Size, shape, and the cabochon color and setting are common giveaway points.
- Read the case back. Engraving depth, font, and reference numbers should be crisp and consistent.
- Ask about the movement. Note whether it is automatic or quartz, whether it hacks, and how the seconds hand sweeps.
- Feel the edges. Sharp transitions between polished and brushed areas usually mean rushed finishing.
42mm Versus 40mm on the Wrist
A common rule of thumb is to keep case diameter under roughly 70 percent of your wrist width, though taste and style override it constantly. If your wrist measures about 17 cm (roughly 6.7 inches) across the top, a 42 mm cushion case lands at the larger end of a comfortable fit and will look like a statement piece. The same case on a 15 cm wrist tends to overhang the wrist edges. Lug-to-lug length matters more than diameter here, so ask for that number too.
Legal and Practical Limits
Counterfeit watches are illegal to import or sell in many countries, and the practical downsides are just as real. A replica cannot be serviced by the brand, holds no resale value, and often uses a generic movement with no parts support. If your goal is the 42 mm Drive look, compare the official dimensions and finishes first, and treat any listing that avoids specific measurements as a warning sign.
Quick Answers
Is 42 mm too big for a daily watch?
Not necessarily. It depends on wrist width and lug-to-lug length. On average to larger wrists, 42 mm is a normal modern size.
Does 42 mm include the crown?
No. Stated case diameter excludes the crown and pushers. A 42 mm case measures around 45 mm or more once the crown is counted.
What should I verify first?
Diameter, lug-to-lug, and thickness. Get those three numbers and the rest of the comparison becomes much easier.
