March LA.B Mansart Small Seconds: Bold Elegance for the Modern Formal Watch
Redefining Dress Watch Convention: The March LA.B Mansart Small Seconds
In a market dominated by round dress watches, the March LA.B Mansart Small Seconds makes a compelling case for angular elegance. This French-designed, Swiss-made timepiece proves that formal watches don't need to be boring — and at $1,722 for stainless steel models, it offers accessible distinction for collectors seeking something different.
The Mansart collection has always been March LA.B's most refined offering, and the Small Seconds variant distills the concept to its essence. By removing the date display and focusing on time-only simplicity, the Mansart Small Seconds achieves the kind of focused elegance that defines great dress watch design.
The Art of Angular Design
The Mansart Small Seconds' octagonal case shape immediately sets it apart from conventional dress watches. Rather than relying on precious materials or complex dials for visual impact, March LA.B uses geometry to create interest. The angular silhouette, combined with the crown positioned at 4 o'clock, creates an instantly recognizable design language.
Measuring 35mm in diameter by 11.1mm thick, with a compact 39mm lug-to-lug presence, the Mansart maintains dress watch proportions while offering surprising wrist presence. The octagonal profile provides more visual surface area than a round watch of similar dimensions, allowing it to hold its own alongside larger sports watches.
The Golden Hour Edition: Luxury Meets Distinction
The premium "Golden Hour" variant elevates the Mansart concept with 18k yellow gold plating (three microns thick) and a matching gold dial. What makes this version particularly interesting is the inclusion of an alternate green dial, allowing owners to customize their watch's appearance — though dial changes require a watchmaker's intervention.
The gold-plated exterior transforms the Mansart from a smart daily wearer to a genuine statement piece. The octagonal crown, also gold-plated, becomes a design feature rather than an afterthought, reinforcing the watch's geometric design language.

The La Joux-Perret G121: A Movement Worth Noting
Powering the Mansart Small Seconds is the La Joux-Perret Caliber G121, an automatic movement based on the popular G100 platform. La Joux-Perret, primarily owned by Citizen (with LVMH recently acquiring a minority stake), produces movements that share architecture with Miyota's Caliber 9000 series but feature upgraded components and improved specifications.
The G121 offers 68 hours of power reserve — significantly more than many competitors in this price range — and operates at 28,800 vph (4Hz) for smooth seconds hand movement. The sub-dial placement at the lower left creates visual balance against the 4 o'clock crown, demonstrating thoughtful design integration.
The Caseback Secret
One of the Mansart's most charming details is hidden from view: a vibrant green-tinted display window on the caseback. This modern, unexpected touch contrasts with the watch's formal exterior, providing a private delight for the wearer. It's the kind of thoughtful detail that elevates a good watch to a great one.
Who Should Choose the Mansart Small Seconds?
This watch appeals to collectors who appreciate:
- Distinctive design — The octagonal case stands out without being ostentatious
- Quality Swiss movement — The La Joux-Perret G121 offers excellent performance
- Versatility — Equally at home with suits or smart casual attire
- Brand heritage — March LA.B's French design sensibility with Swiss manufacturing
- Value proposition — Exceptional quality at under $3,000
Styling Considerations
The Mansart's octagonal shape pairs best with structured clothing. It complements tailored suits, structured blazers, and clean-lined dress shirts. The 4 o'clock crown position means the watch sits comfortably on the wrist without protruding into the hand — a practical consideration for those who spend hours at a keyboard.
For formal occasions, the black alligator strap provides appropriate formality. For daily wear, the stainless steel models with leather straps offer greater versatility.
Frequently Asked Questions
Q: Is the 4 o'clock crown position uncomfortable?
A: Not at all. The crown's position actually improves comfort, as it doesn't dig into the wrist during movement. Many wearers find it more natural than traditional 3 o'clock placement.
Q: Can the gold plating withstand daily wear?
A: Three microns of 18k gold provides reasonable durability, but like all gold-plated watches, it will show wear over time. For maximum longevity, consider the stainless steel models for daily wear and reserve the Golden Hour for special occasions.
Q: How does the power reserve compare to competitors?
A: At 68 hours, the Mansart offers significantly more power reserve than many watches in its price range. This means you can set it down Friday evening and find it still running Monday morning.
