The S.T. Dupont Ligne 1 Small, gold-plated with Pointe de Diamant, is one of the most cherished lighters in the modern history of the Parisian house. This example dates from the 2000–2010 period and represents the Ligne 1 in its final production form: refined, timeless, and crafted using the same artisanal methods as the very first models from the 1950s. The characteristic “Cling” sound that rings out when opened is just as clear and precise as when it was first produced—direct proof of a mechanism in excellent condition.
The Small size (35 × 14 × 47 mm) is the most portable model in the Ligne 1 family. Compact enough to fit in a jacket pocket, yet substantial enough to feel unmistakably present in the hand. The entire exterior is plated in yellow gold and features the Pointe de Diamant pattern—a precise network of pyramid shapes that captures the light from every angle. This pattern also provides a natural, non-slip grip.
Handcrafted serial number — proof of authenticity
On the underside, this piece bears the complete manufacturer’s markings: the calligraphic signature “S.T. Dupont — PARIS — MADE IN FRANCE” and the hand-stamped serial number 1J4BN89. Every S.T. Dupont serial number is unique to each lighter and serves as the most reliable guarantee of authenticity that a vintage Dupont can bear.
Mechanical Condition
The gold-plated finish is in brilliant condition, with no structural wear, dents, or dings. Only very slight, superficial signs of careful use over the years are present. The mechanism functions perfectly: the flame adjustment slider operates smoothly, the lid opens and closes with absolute precision, and the lighter produces a reliable flame immediately.
Gas Refills and Maintenance
The Ligne 1 Small runs on butane gas and requires the yellow S.T. Dupont gas refill. In accordance with postal safety regulations, the lighter is shipped empty. For flints, use the black S.T. Dupont flints (REF 900601). The Ligne 1 is the lighter that marked S.T. Dupont’s transition from gasoline to gas in 1952. A specimen in this condition, from the final production run of this model (discontinued in 2013), is no longer available for reorder.
