Charles Girardier is the sort of name that rewards a little context.
Revived in recent years by collector Patrick Ulm, the maison has built its identity around a thoughtful reading of Genevan decorative watchmaking rather than a simple exercise in nostalgia.
The new Plénitude collection, unveiled at Watches & Wonders 2026, pushes that idea forward with two variants, the PL1 and PL2, and a broader move toward in-house-developed watchmaking.

At a glance
- Charles Girardier has introduced the Plénitude collection in PL1 and PL2 variants.
- The line includes the Plénitude Volcano Power Reserve and the Plénitude Lunar Phase, with multiple dial colourways.
- The launch marks a step deeper into manufacture development from the brand’s atelier in Buchs.
A historic Genevan name with modern intent
Charles Girardier was born in Geneva in 1759, at a time when the city’s reputation for fine watchmaking was being shaped by a network of specialist artisans.
That ecosystem, often associated with the city’s famed workshop culture, allowed engravers, enamellers, guilloché specialists, miniature painters and movement makers to operate with remarkable independence while serving a common trade.
Girardier opened his own workshop at just 21 and signed his watches Girardier L’aîné, a detail that still gives the name an intriguing air of self-invention.

His surviving work shows a particular command of enamelling and automata, including complicated pocket watches with animated figures, repeating mechanisms and richly decorated cases.
The modern Charles Girardier was registered in 2018 by Patrick Ulm after his interest in a historic pocket watch led him deeper into the watchmaker’s life and craft.
That revival gained early credibility in 2020, when the Signature Mystérieuse Fleur de Sel won the Ladies’ Complication Watch Prize at the GPHG.

With its Grand Feu enamel dial, flying tourbillon and animated mysterious signature, the watch set the tone for the brand’s current philosophy.
It wasn’t trying to recreate the past, but to imagine how Girardier’s decorative and mechanical instincts might translate into contemporary wristwatches.
The Plénitude collection takes shape
The Plénitude arrives as a new family rather than a single watch, with PL1 and PL2 references and several dial treatments.

Two expressions define the collection’s early character, the Plénitude Volcano Power Reserve and the Plénitude Lunar Phase.
The Volcano Power Reserve is offered in White Pearl, Champagne and Majestic Purple.
The Champagne and Majestic Purple versions use a sunray finish, while the White Pearl dial is cleaner in treatment, allowing the colour and surface to carry the composition more quietly.

The Lunar Phase brings a different emotional register to the same collection, including a Blue Ocean version that leans into a more atmospheric reading of the complication.
For an independent brand of this scale, the importance of Plénitude sits less in one headline feature and more in what it suggests about direction.
Charles Girardier has already shown it can work with automata, enamel, tourbillon architecture and poetic display concepts.

Plénitude now gives the house a platform to express those instincts in a broader, more systematic collection.
Buchs and the manufacture ambition
The move to Buchs in the canton of Aargau is an important part of the Plénitude story.
Charles Girardier’s atelier now sits within a small but serious watchmaking environment that also includes Cyrano Devanthey and Dominique Büser of Oscillon.

It’s a notably Swiss arrangement, independent workshops pursuing their own ideas while remaining close enough to exchange specialist knowledge when the work demands it.
That matters because Plénitude is connected to the brand’s ambition to create a fully in-house-developed manufacture movement.
For collectors, that phrase carries weight only when it’s backed by coherence, finishing and a clear horological purpose.
In the case of Charles Girardier, the appeal is the combination of historical decorative language and a modern independent setup that’s still small enough to feel personal.
