A counterfeit tumbaga de Cartier is a watch that copies the warm gold-copper case tone of Cartier's vintage tumbaga pieces without using the real alloy or the maison's finishing. This guide explains what tumbaga is, how counterfeits are built, and what to inspect before you buy one.
What Is a Counterfeit Tumbaga de Cartier?
Tumbaga is a gold-and-copper alloy that Cartier used on a number of mid-century cases, valued for a soft rose-gold glow that ages differently from solid gold. A counterfeit tumbaga de Cartier reproduces that look — the color, case shape, and engraved markings — while substituting brass, plated base metal, or a lower-carat blend underneath. It can photograph identically to the original and still feel, weigh, and wear nothing like it.

Materials and Specifications
Metal is where these pieces live or die. Real tumbaga is an alloy through and through, so its color survives polishing and shows a consistent grain under magnification. Counterfeits are usually brass or zinc alloy carrying a thin electroplated layer, often 2 to 10 microns, that thins first at the lugs and crown where the wrist rubs. Weigh the case in the hand: a genuine gold-copper alloy has real heft for its size, while plated base metal feels light and rings hollow when tapped. Inspect hallmarks with a loupe — crisp, uniform stamps are a good sign, shallow or crooked markings are not.
Shipping and Returns
Orders ship in discreet packaging with tracking, usually within one to two business days, and delivery timelines are confirmed at checkout. If a piece arrives not matching its listing — wrong case size, plating flaws, or movement issues — returns and exchanges are accepted within the stated window as long as the watch comes back unworn with its tags. Contact support first and return instructions will be issued.
How Do You Tell a Counterfeit Tumbaga de Cartier From a Real One?
Start with weight and wear points. Genuine tumbaga keeps its color at the lugs and caseback, while plated fakes show grey or yellow metal bleeding through. Then compare hallmarks, dial printing, and crown proportions against documented reference photos of that exact model.
Is Tumbaga the Same as Solid Gold?
No. Tumbaga is a gold-and-copper alloy with a lower precious-metal content than solid gold, which is why it develops such a distinct patina over decades. That aged tone is precisely what counterfeiters try to fake with plating.
