Hand saddle-stitched, blind-stamped and made one at a time — which is exactly what a factory cannot copy.

Hermès is the one maison where the decisive check is not a mark but a technique. Bags are saddle-stitched by hand, two needles passing through the same hole from opposite sides, which produces a stitch that leans, varies almost imperceptibly in length, and cannot unravel when cut. A machine cannot do it. Every counterfeit therefore fails at the seam, and no amount of investment in hardware or leather closes that gap.
Everything else supports that read: the blind stamp that dates the bag, the craftsman's mark beside it, the hardware plating, and the particular grain of the leathers the maison uses. But the stitch comes first, and on a Birkin or Kelly it is visible along the handle base and the piping without opening the bag.
The market around Hermès is also unusual. Because the maison rations its most wanted bags, a large trade exists in bags that were never for sale in the ordinary way, and with it a trade in convincing fakes and in genuine bags with replaced parts. Restored, re-dyed and re-hardwared bags are their own category and are not the same as counterfeits.
Hermès dates its bags with a single letter stamped without ink — a blind stamp — usually on a strap, under a flap or on the interior. What surrounds that letter identifies the era, and the shapes have changed three times.
From 1971 to 1996 the date letter sits inside a circle. From 1997 to 2014 it sits inside a square. From 2015 the surrounding shape was dropped and the letter stands alone. Before 1971 a letter was used without any surround as well, so a bare letter is either very old or quite recent and the rest of the bag has to decide which.
Beside the date letter is the craftsman's number — the mark of the artisan who made the bag. It is deliberately not a public register: you cannot look it up, and any service claiming to trace it is selling you something. Its value is physical. A genuine blind stamp is pressed into the leather cleanly, without ink, at a consistent depth, and it does not sit on top of the surface.
From around 2017 the stamp's position moved on several models, generally to a less visible spot. That relocation is worth knowing, because a seller insisting the stamp 'should' be on the front strap of a recent bag is working from an outdated guide.
| Period | Date stamp | Where to look |
|---|---|---|
| Before 1971 | Letter alone | Interior or under the strap |
| 1971 – 1996 | Letter in a circle | Front strap, under the flap |
| 1997 – 2014 | Letter in a square | Front strap, under the flap |
| 2015 onward | Letter alone | Position varies; often relocated inside |
The letter dates the bag. It says nothing about authenticity by itself, and counterfeit stamps are routinely correct in form and wrong in depth.
Ordered by how much each one settles. The decisive checks are the ones worth your first five minutes; the supporting ones only matter once those are clean.
Two needles, one thread, worked by hand from both sides of the leather. The result is a stitch that slants consistently in one direction on one face and the opposite on the other, with almost imperceptible variation in length — regular but not mechanical. A machine lockstitch is perfectly uniform and sits straight. This is the decisive check on any Hermès bag, and it is visible along the handle bases and the piping.
Pressed into the leather without ink, evenly, so it reads as a change in the surface rather than a mark on it. Run a thumbnail across it: a genuine stamp has real relief. A stamp that is inked, shallow, or crisp at the edges in the way printing is crisp, is a failure regardless of whether the letter is correct for the claimed year.
Hermès hardware is solid, plated in palladium or gold, and heavy for its size. The HERMÈS PARIS engraving on a Birkin or Kelly plate is deep, evenly spaced and correctly accented. Screws on the hardware are finished flush. Plating that has worn thin will dull and show base metal in a gradient; plating that flakes off in patches was never that thick.
Togo, Clemence, Epsom, Box and Chèvre each behave differently and are not interchangeable. Epsom is embossed, stiff and holds a sharp corner; Togo is a natural pebbled grain that softens; Box calf is smooth and shows every mark. A bag described as one leather that behaves like another is either mis-described or not what it says it is.
The touret and sangles on a Birkin engage with a firm, precise action and no play. The clochette — the small leather bell holding the keys — is stitched by the same hand and in the same thread as the bag, and its stitching should match. A clochette whose stitch is machine-regular while the bag's is not is a replaced part or a giveaway.
The base studs are set square, at even intervals, and screwed rather than pressed. They wear on their outer edges from being set down. Studs that sit proud unevenly, or whose bases have begun to pull at the leather, indicate either a hard life or hardware fitted after the fact.
Counterfeit Hermès occupies the top of the fake market, and money has been spent on it — correct hardware weight, correct leathers, correct stamps. It still cannot buy the hand stitch, because the whole economics of counterfeiting rest on machine speed and saddle stitching is slow, skilled handwork.
The larger practical risk with Hermès is not the outright fake but the altered genuine bag: a real Birkin with replaced hardware, a re-dyed body, a swapped strap, or restoration passed off as original condition. Those are legally genuine and commercially very different, and they are read by looking for stitching that changes character partway along a seam.
Each of these is checked differently. The ones with their own page have enough that is specific to them to be worth reading separately.
