Old Line 1 vs New Line 1 vs Ligne 2: What’s Really Changed

When S.T. Dupont reintroduced the iconic Line 1, it immediately sparked curiosity among collectors and enthusiasts alike. For many, the Linge 1 represents a piece of history—an elegant lighter that defined an era of craftsmanship and precision.

So naturally, questions began to surface. How does the new version compare to the original Line 1 models? More importantly, how does it stand against the highly regarded Ligne 2, which has long been considered the benchmark for luxury soft flame lighters?

This guide takes a closer and more detailed look at the differences between the Old Line 1, the New Line 1, and the Ligne 2. From size and proportions to flame systems, usability, and overall design philosophy, we break down what has changed—and what these changes mean for both collectors and everyday users.

New Line 1 vs Old Line 1

Size and Proportions

One of the first things you’ll notice about the new Line 1 is its updated and refined form factor. It sits comfortably between the original Small and Large versions but introduces a noticeably more modern profile.

• Old Line 1 Small: approximately 1.85" x 1.37" x 0.55"
• Old Line 1 Large: approximately 2.28" x 1.37" x 0.55"
• New Line 1: approximately 2" x 1.46" x 0.47"
  
  
  

The most significant difference lies in the thickness. The new Line 1 is considerably slimmer than both earlier models, giving it a sleeker appearance and a more ergonomic feel in hand. While the overall footprint remains familiar, this reduction in thickness aligns perfectly with contemporary preferences for slimmer, more pocket-friendly designs.

In practical terms, this means the new Line 1 feels less bulky and more refined, making it easier to carry while still maintaining the recognizable silhouette that defines the Line 1 family.

Flame Mechanism

The flame system is where the new Line 1 introduces one of its most meaningful upgrades.

• Old Line 1: Single soft flame
  
  
• New Line 1: Dual soft flame system
  
  
  
  
  

Traditionally, Line 1 lighters featured a single soft flame, emphasizing elegance, simplicity, and controlled ignition. While this design worked well, it was somewhat limited in versatility.

The new version evolves this concept by incorporating a dual soft flame system. This upgrade not only improves ignition reliability but also provides a broader and more consistent flame, making it more adaptable to different lighting conditions. Whether indoors or outdoors, the dual flame adds a level of performance that was previously absent from the Line 1 series.

Flame Adjustment

Another important improvement lies in how the flame is adjusted.

• Old Line 1: Adjustment located under the lid
  
  
  
• New Line 1: Adjustment moved to the bottom
  
  
  

On older models, users had to open the lid to access the flame adjustment wheel. While functional, this design was not particularly convenient for frequent adjustments.

The new Line 1 relocates this control to the base of the lighter, making it far more accessible. This small but impactful change significantly improves the overall user experience, especially for those who value ease of use and efficiency.

Bottom Construction

This redesign naturally leads to a more functional bottom layout.

• Old Line 1: Refill valve only
• New Line 1: Refill valve + flame adjustment dial
  
  
  

By consolidating both the refill valve and the adjustment dial at the bottom, the new Line 1 offers a cleaner and more intuitive design. This approach reflects a broader trend in modern lighter engineering—prioritizing convenience without sacrificing aesthetics.

It also brings the Line 1 closer in line with other contemporary models within the Dupont range.

Overall Impression

The new Line 1 successfully preserves the identity and elegance of the original while modernizing its functionality. It is slimmer, more versatile, and better aligned with current expectations.

For long-time collectors, it feels like a respectful evolution rather than a radical redesign. For new users, it offers a refined entry point into the world of luxury lighters.

New Line 1 vs Ligne 2

Size and Feel

Comparing the new Line 1 to the Ligne 2 reveals a noticeable shift in positioning.

• Ligne 2: approximately 2.44" x 1.45" x 0.43"
  
  
  
• New Line 1: approximately 2" x 1.46" x 0.47"

While the new Line 1 is shorter in height, its thickness is very close to that of the Ligne 2. This gives it a more substantial and premium feel compared to earlier Line 1 models.

In hand, the difference is subtle but meaningful. The new Line 1 feels more solid than its predecessors, bridging the gap between compact design and premium weight.

Flame System

Both models remain firmly rooted in soft flame lighter design, a hallmark of S.T. Dupont craftsmanship.

• Ligne 2: Traditional soft flame (including dual flame variants)
  
  
  
• New Line 1: Dual soft flame system

The introduction of a dual flame in the new Line 1 allows it to compete more directly with the Ligne 2 in terms of performance. While Ligne 2 has long been praised for its consistency and smooth ignition, the new Line 1 now offers comparable functionality in a slightly more compact form.

Flame Adjustment

In this area, the two models are now fully aligned.

• Ligne 2: Bottom-mounted adjustment
• New Line 1: Bottom-mounted adjustment

This consistency creates a seamless user experience across both models. Users familiar with one will find the other immediately intuitive, which is particularly valuable for collectors who own multiple Dupont lighters.

Design and Presence

This is where personal preference becomes the deciding factor.

• Ligne 2: Larger, more prominent, flagship model
  
  
  
• New Line 1: Slimmer, more discreet, lower profile

The Ligne 2 is widely regarded as the flagship soft flame model, known for its iconic “ping” sound and commanding presence. It is often chosen by those who appreciate tradition and a more substantial feel.

In contrast, the new Line 1 offers a more understated alternative. Its slimmer design and reduced height make it ideal for users who prefer something elegant yet less visually imposing.

Conclusion

The reintroduction of the Line 1 fills an important gap in the S.T. Dupont lineup. It successfully bridges the space between classic heritage and modern functionality.

• Compared to the old Line 1, the new version is slimmer, more versatile, and significantly more practical
• Compared to the Ligne 2, it provides a more compact alternative while maintaining a similar level of usability

For collectors, the new Line 1 represents a meaningful addition to an already rich legacy. It respects the past while embracing the future.

For everyday users, it offers a balanced option—combining portability, performance, and refined design in a way that feels both modern and timeless.

Ultimately, the choice comes down to personal preference. Whether you value tradition, modern innovation, or the perfect blend of both, there is now a Line 1 or Ligne 2 that fits your style.
