Constance 18: real vs fake
The Constance is the one iconic Hermès model where the logo IS the closure: the oversized “H” buckle on the flap. That’s exactly what replicas fail most often – in proportions, finish, and seating. The second signature trait is the long strap, worn doubled on the shoulder or at full length crossbody.
What to check on the Constance 18
Model-specific zones – on top of the brand-level signs.
The “H” clasp
The H buckle is oversized, dead-center on the flap, with polished edges and no burrs. It comes in plain metal or with an enamel inlay. Compare the bar proportions: replica H’s often run too thick or too narrow.
Flap seating on the H
The flap lands on the clasp evenly: the H cutout is symmetrical, gaps match on all sides, and the closure locks in cleanly with no skew. A flap that wanders around the clasp is a typical counterfeit defect.
Double-wear strap
The Constance’s long strap is worn crossbody or doubled over the shoulder. Check that the leather is uniform along its full length and that the attachment points to the body are cleanly finished.
Accordion gussets
The sides fold accordion-style and expand evenly, mirror-matched left to right. Crooked or unevenly creasing pleats give away a cheap cut.
Back exterior pocket
The flat pocket on the back panel should have a straight opening with no gaping or wavy edge. Replicas often simplify or skew its geometry.

FAQ
Is an enamel H clasp a fake sign?
No – Hermès makes the Constance with both plain metal and enamel-inlaid H clasps. Judge the quality: even fill with no bubbles, polished edges, and symmetrical letter proportions.
How do I tell a Constance 18 from a 24?
By the H’s scale against the flap and the overall size: the 18 is compact, roughly 18–19 cm wide, with the clasp taking up a hefty share of the front. The 24’s body is clearly wider, making the H look proportionally more modest.
The strap doesn’t detach – is that normal?
Yes. On the classic Constance the strap is fixed: it’s designed as a single double-wear loop – crossbody or doubled on the shoulder. A detachable strap should raise questions rather than settle them.
