THE MOON TAKES CENTER STAGE

SENANS
GRANDE LUNE

Introducing the Senans Grande Lune, YEMA's first moonphase timepiece and the inaugural model of the new Senans collection.

A sculpted, luminous Big Moon takes a prominent place on an intricately textured dial, transforming a traditional complication into the defining feature of the watch. Distinctive in its design yet classical in its proportions, the Grande Lune brings a fresh perspective to the traditional dress watch.

Powered by our Manufacture micro-rotor movement, the Grande Lune combines an ambitious lunar complication with the refined proportions of a stainless steel case measuring just 8.70 mm thick.

Limited to 200 pieces per dial colour.

IN THE PRESS

“YEMA is producing some surprising watches that reach well beyond the brand’s signature repertoire of tool watches. The latest surprise is the launch of the new and dressier Senans collection, spearheaded by the brand’s first moon phase watch in a delectably slim case. (…) Quite a pleasant price considering the mechanical content…”

A GRAND PERSPECTIVE
ON THE MOON


Traditionally confined to a small aperture, the moonphase complication takes on an entirely different scale in the Senans Grande Lune, where a strikingly large lunar display becomes the defining feature of the dial.

Positioned asymmetrically at 7 o’clock, the prominent lunar display immediately draws the eye and defines the character of the dial. The surrounding guilloché textures, hour markers and open space counterbalance its unconventional placement, giving the dial a distinctive yet carefully balanced design.

The generous curve of the lunar aperture echoes the semicircular architecture of the Royal Saltworks of Arc-et-Senans, the landmark that inspired the Senans collection.

Unlike conventional flat moonphase discs, the Senans Grande Lune features a three-dimensional moon, giving the lunar display a sculptural presence.

A rotating mechanical bilobe gradually reveals and conceals the moon, recreating the succession of lunar phases. A familiar astronomical cycle unfolds on your wrist, inviting a closer look each day.

PATTERNS INSPIRED BY NATURE


The central dial features an intricate barleycorn guilloché pattern inspired by the Fibonacci sequence and the natural geometry of sunflowers and pine cones. Its repeating grain-shaped motifs form intersecting spirals that give the dial a sense of rotation and depth.

As light moves across the surface, changing reflections reveal the fine relief and geometry of the pattern, creating an impression of movement even when the watch is still.

Surrounding the central guilloché, a circular-brushed surface provides a smoother contrast, while a concentric Super-LumiNova ring defines the transition between the two textures.

From daylight
to moonlight


Crafted from a solid 3D block of Grade X Super-LumiNova using Globolight technology, the Moon forms a sculptural, three-dimensional luminous element.

Its subtly domed surface features finely detailed lunar markings, reproducing the characteristic craters and irregular textures of the moon’s surface. By day, these details give the display realism and depth. As darkness falls, the moon reveals a different character, emitting a soft, warm glow reminiscent of natural moonlight.

Concentric Super-LumiNova rings frame the central guilloché like luminous halos, extending the moon’s glow across the dial. The hands and applied hour markers are also treated with Grade X Super-LumiNova, ensuring clear timekeeping in low-light conditions.

CLASSICAL STEPPED CASE DESIGN


The Senans Grande Lune features a classical stepped case, distinguished by its layered construction, where the bezel rises in successive levels above the case middle. This traditional watchmaking design adds depth and definition to the case, with each step catching the light and drawing the eye towards the dial.

Measuring 38.5 mm in diameter, just 8.70 mm thick and 46 mm from lug to lug, the 316L stainless steel case combines classical proportions with a comfortable wrist presence.

The mirror-polished bezel and upper surfaces contrast with vertically brushed sides, emphasising the stepped architecture, while gently curved lugs follow the contours of the wrist. Its slim profile allows the watch to slip easily beneath a shirt cuff.

A double-domed sapphire crystal with anti-reflective coating completes the case, its gentle curvature recalling traditional watch crystals while providing a clear view of the intricate dial and sculpted lunar display.

THE ENGINEERING BEHIND THE BIG MOONPHASE


Integrating a large moonphase complication into an ultra-thin automatic movement presented a significant mechanical challenge.

The larger lunar mechanism introduced additional mass and inertia compared with conventional, smaller moonphase displays. This required careful refinement of component dimensions, gearing and the transmission of power through the mechanism.

YEMA’s movement engineers developed the mechanism through successive stages of design and prototyping, incorporating a complication measuring just 0.83 mm thick. A quick-adjustment system allows the wearer to set the lunar display conveniently, adding a further engineering challenge within the limited space available.

Building on YEMA’s 3.7 mm CMM.20 micro-rotor architecture, the team integrated the moonphase complication while adding less than 1 mm to the base movement’s thickness.

The resulting CMM.22 Manufacture caliber remains remarkably thin, allowing the Senans Grande Lune to combine its prominent lunar display with a slender 8.70 mm case profile.

MADE IN THE JURA

Over the last few years, YEMA has gradually brought the manufacture of its proprietary calibers in-house, investing in modern equipment and production lines. The watch’s habillage (cases, dials, hands and straps) come from partners in France and Switzerland, all within 72 km from YEMA’s workshops in Morteau, the cradle of French watchmaking. Together they belong to the Franco-Swiss Jura watchmaking community, which UNESCO recognised as Intangible Cultural Heritage in 2020.

THE CMM.22 REVEALED IN ANTHRACITE


Visible through the sapphire exhibition caseback, the CMM.22 Manufacture caliber is derived from YEMA’s CMM.20 micro-rotor architecture, adapted for the Big Moon complication and finished in deep anthracite.

A rich charcoal grey with subtle metallic undertones, anthracite offers a distinctive alternative to traditional silver-toned movement finishes. Its darker surfaces bring definition to the movement’s architecture, creating a striking contrast with the polished screw heads, jewel bearings and brushed micro-rotor.

This finish is achieved through an Anthradec electroplated surface treatment. Applied in an exceptionally thin layer, the coating combines high surface hardness with good chemical stability, preserving the fine detail of the underlying surfaces.

Against this dark background, metallic components catch the light and the micro-rotor turns with the movement of the watch. The view through the caseback reveals another side of the timepiece, pairing its classical exterior with a distinctly contemporary movement.

Leather or Milanese mesh

Grained leather strap


The leather strap’s pronounced pebbled grain echoes the irregular, mineral texture of the lunar surface, complementing the watch’s classical proportions. A smooth leather lining provides a soft feel against the wrist for comfortable daily wear.

A 316L stainless steel pin buckle features vertically brushed surfaces, polished chamfers, and an engraved YEMA signature.

INTEGRATED MESH BRACELET 


Engineered specifically for the Senans Grande Lune case, the 316L stainless steel mesh bracelet follows the contours of the wrist, bringing a supple feel and finely woven texture to the watch.

Curved, solid end-pieces integrate seamlessly with the case, while a quick-release system allows the bracelet to be easily removed and exchanged for a leather strap without the need for tools.

A satin-brushed sliding clasp, finished with a polished YEMA logo in relief, allows fine adjustment for a comfortable, precise fit.

Senans

INSPIRED BY FRENCH ARCHITECTURAL HERITAGE


The Grande Lune inaugurates a new family of YEMA timepieces inspired by the Royal Saltworks of Arc-et-Senans, an 18th-century architectural landmark in eastern France, not far from YEMA's workshops in Morteau. Designed by architect Claude-Nicolas Ledoux during the Age of Enlightenment and recognised as a UNESCO World Heritage Site, the Royal Saltworks is celebrated for its distinctive semicircular layout.

Built between 1775 and 1779, the Royal Saltworks represents an ambitious vision of architecture in which classical proportions, geometric precision and industrial purpose come together. Its buildings are arranged around a central space, creating a monumental composition defined by symmetry and sweeping curves.

Taking its name from Arc-et-Senans, the new Senans collection draws inspiration from this architectural heritage. The sweeping semicircular geometry of the Royal Saltworks finds an echo in the Grande Lune's lunar aperture, creating a visual connection between the historic monument and the watch's defining complication.
