How to Identify your S.T. Dupont Lighter - Le Grand

Identifying the S.T. Dupont Le Grand & New Le Grand Lighters

The S.T. Dupont Le Grand is one of the brand’s most technically innovative lighters, known for its dual ignition system—offering both a soft flame and a torch flame in a single body. Over time, it’s undergone a few design changes, so here’s how to tell if you have the original Le Grand or the updated New Le Grand.

First Generation Le Grand

-Typical Size: Approx. 66mm x 39mm x 14mm

-Flame Type: Dual ignition (soft flame + torch flame)

-Bottom Access Panel: Hinged metal flap conceals both the refill valve and flame adjustment screw

-Flint Access: A button under the lid unlocks the flint compartment, which swings open

-Sound: Typically does not have the signature "ping"

-Flame Control: Roll the ignition roller for soft flame, push up once ignited for torch flame

-Other Notes: Bottom flap must be opened to refill butane or adjust flame height

New Le Grand

-Size:  Approx. 66mm x 39mm x 14mm

-Flame Type: Still dual ignition, but more refined ignition system

-Bottom Design: Mimics the Ligne 2 bottom—no flap; refill valve and adjustment screw are exposed under a recessed cover

-Flint Access: Still under the lid but now requires the use of a screwdriver (included with the lighter) to remove the flint plate

-Sound: Most metal models are engineered to produce the signature “ping”

-Visual Differences: Bottom markings are more in line with current Ligne 2 and D-influenced styling
