A replica Drive 42mm blue is a cushion-shaped watch built to copy the Cartier Drive de Cartier: a 42mm wide case, a blue dial with Roman numerals and a railroad minute track, a fluted crown with a blue cabochon, and a leather strap on a folding clasp. The versions worth buying run a mechanical automatic movement, sapphire crystal, and a dial with applied markers. The versions to skip run quartz, mineral glass, and flat printed dial text.

Reference Points to Match

Measure or ask about these before you pay. Numbers that are off by more than half a millimeter show up on the wrist.

  • Case width: 42mm across the middle, cushion shape with softened corners.
  • Thickness: about 10mm to 12mm, depending on whether the build uses a chronograph caliber.
  • Lug to lug: measure it, because a cushion case wears wider than a round 42mm.
  • Crystal: sapphire, flat or domed, with no visible glue line at the edge.
  • Crown: fluted, set with a blue cabochon, aligned with the 3 o'clock position.
  • Dial: blue with a sunray or guilloche pattern, applied Roman numerals, and a printed minute track.

How to Inspect One

  1. Ask the seller for the case width, thickness, and lug to lug in millimeters, then compare them to the reference dimensions published by Cartier.
  2. Look at the dial under a loupe and check that the Roman numerals sit above the surface and that the minute track is sharp.
  3. Turn the watch over and read the caseback engraving, which should be crisp, centered, and cut rather than laser-etched and shallow.
  4. Hand wind the crown through 20 turns and feel for grit or a rough ratchet, then set the time and check that the hands move without jumping.
  5. Time the watch for 24 hours against a phone clock and note the daily rate before you decide.
  6. Flex the strap at the lugs and inspect the stitching and the clasp, which are the two parts that fail first on cheap builds.

Movement Options

Three calibers show up often. A Miyota 9015 is the safest automatic for a time-only build, since parts and service are easy to find. A Seagull ST19 or a similar column wheel copy drives most chronograph versions and looks right through a display back. Quartz builds are cheaper and thinner, but the second hand ticks instead of sweeping, which is the first thing anyone notices. Ask which one is inside before you buy.

Red Flags

  • Photos that avoid the crown side or the caseback.
  • Sapphire claims with no scratch test and no coating note.
  • Dial text that is flat, fuzzy, or spaced wrong.
  • No stated movement, no stated dimensions, and no return window.

A replica is not the original and carries no brand warranty, so treat every claim as unverified until the watch is in your hand. Buy from a seller who answers measurement questions in writing and takes returns.
