The reference point here is the genuine Panthère de Cartier Large, in steel on the brick-link bracelet. I am judging it on five criteria: case proportions on the wrist, how the bracelet articulates, dial printing and hand finish, movement and serviceability, and what the watch holds if you ever sell it. This guide does not route you to replica sellers. It explains what the Large is, how it compares with the other sizes and metals, and where counterfeits give themselves away, so your money gets spent once.

What "Large" means in the Panthère line

Cartier introduced the Panthère in 1983 and brought it back as a core collection in 2017. The modern lineup runs small, medium and large, plus gem-set and skeleton variants that sit outside this comparison. The Large is the biggest of the three classic cases, roughly 37 mm lug to lug and around 27 mm across, which reads as a dress watch on a 6.5 inch wrist and as a subtle piece on a 7.5 inch wrist. Confirm current figures with an authorized dealer before you commit, since Cartier has adjusted dimensions on some references.

Shared traits across the range: a square case with rounded corners, a sapphire cabochon set into the crown, Roman numerals on a silvered dial, blued sword hands, sapphire crystal, water resistance rated for splashes rather than swimming, and a quartz movement. The bracelet is the design event. Flat brick links sit close to the skin and taper toward a hidden folding clasp, which is why the watch wears smaller than its dimensions suggest.

Option 1: Large in steel

The steel Large is the version most people picture when they hear the name, and it is the one I would start with.

  • Pros: lowest entry point in the line, the most versatile finish, pairs with a t-shirt or a suit, bracelet hides scratches better than polished gold, strong demand if you resell.
  • Cons: steel is the most counterfeited configuration, so buying secondhand demands paperwork and a service check.

Use case: a single watch worn several days a week. If you want one Panthère and no rotation, this is it.

Option 2: Large in yellow or rose gold

Gold changes the watch from jewelry-adjacent to outright jewelry.

  • Pros: warmer presence on the wrist, the cabochon and blued hands read better against gold, holds value well in yellow gold, feels special at formal events.
  • Cons: higher outlay, polished surfaces show hairline scratches quickly, softer metal means more careful handling.

Use case: an evening or occasion piece, or a gift marking something specific. Not the pick for daily wear if scratches bother you.

Option 3: Medium

The Medium is the size most wrists actually want, and it deserves a look before you default to Large.

  • Pros: proportions feel closer to the 1980s original, sits flatter under a cuff, same bracelet design and dial language, often easier to find in stock.
  • Cons: less wrist presence if you have a wider wrist, and some buyers find it reads as a small watch rather than a slim one.

Use case: wrists under about 6.5 inches, or anyone who wears a watch with a tightened shirt cuff. Try both sizes on the same day before deciding.

Option 4: A 1980s original

Vintage Panthères from the first run trade for less than current production and carry the era's lighter case.

  • Pros: genuine heritage, lower cost of entry, distinctive on the wrist.
  • Cons: quartz movements need service, bracelets stretch, parts availability is thinner, condition varies wildly.

Use case: a collector who will budget for a movement service and can inspect a bracelet in person.

Where replicas of the Large fall apart

A good counterfeit can photograph well. In the hand, the gap shows up in predictable places.

  • What can look close: overall silhouette, dial layout, the general shape of the link pattern.
  • What does not: bracelet articulation, which feels stiff and rattly instead of fluid; dial printing, which sits heavier and less crisp; the cabochon, often glass or dyed stone rather than a clean synthetic sapphire; hand finish, with flat blued paint instead of heat-treated steel; caseback engraving depth; and the clasp, which closes with a tinny click.
  • The larger problem: no service path, so a dead movement means a dead watch. Counterfeit trademarked goods are subject to seizure at the U.S. border, and resale value is effectively zero because no reputable dealer will touch it.

Authentication checklist

  1. Match the serial and reference numbers on the caseback to the paperwork, and confirm the paperwork came from an authorized dealer.
  2. Look at the cabochon under light. It should be a clean dome with a visible setting, not a glued bead.
  3. Run a finger along the bracelet edge. Genuine links are finished on every surface, including the inner faces.
  4. Check the dial text with a loupe. Spacing should be even and the paint should sit flush.
  5. Ask for a recent service invoice or have a watchmaker open the case before money changes hands.

Bottom line

Buy the steel Large if you want one watch that does everything, drop to the Medium if your wrist runs small, and go gold only if the piece is meant for occasions. Skip the replica tier: the bracelet and the serviceability are the two things that make this watch worth owning, and those are the two things a counterfeit cannot deliver.
