Yema Watch: Senans Grande Lune CMM.22 Black

Yema Senans Grande Lune: the contrast of guilloché black and a Moon in relief, the first phase of the moon manufacture by Yema

The black Yema Senans Grande Lune inaugurates a new family of dress watches inspired by the Saline royale d’Arc-et-Senans, in Franche-Comté. On the black dial, the Moon in relief immediately catches the eye. The guilloché remains discreet from the front, then reveals itself when the light glides over the surface; the polished indices structure the perimeter without cluttering the display. This version is limited to 200 pieces, like each of the two other colors.

The 38.5 mm 316L steel case measures only 8.70 mm thick, with a 46 mm lug-to-lug. Its multi-level bezel, called a "step case", alternates light reflections above the case. The polish of the bezel contrasts with the vertically satin-finished sides; a anti-reflective treated double-dome sapphire opens the view of the black dial.

The automatic micro-rotor Manufacture CMM.22 caliber animates the two hands and the moon phase. A mechanical element in the shape of a bilobe gradually reveals and then hides the sculpted Moon, with quick correction by the crown. Made from a block of Super-LumiNova Grade X by Globolight technology, it becomes luminous in the dark, accompanied by the hands, the indices, and the concentric rings of the dial.

The watch is offered on grained leather or 316L steel Milanese mesh. The leather closes with a pin buckle; the integrated Milanese has curved end links, quick change, and a sliding clasp. The 50 m water resistance completes this construction, while the sapphire case back allows a view of the anthracite finish of the movement and its micro-rotor.

Why choose this watch?

The black Yema Senans Grande Lune places the moon phase at the center of its identity. The black dial accentuates the presence of the Moon and lets the guilloché gradually reveal itself. This version favors contrasts between surfaces rather than a bright color.

For a moon display that is looked at as much for its mechanics as for its design. The sculpted Moon at 7 o'clock changes appearance throughout the cycle, while the bilobe gradually hides it. The luminescence reveals another reading of the dial once the light is low.

To combine this complication with a case only 8.70 mm thick. The Yema manufacture micro-rotor contributes to this slimness and remains visible through the case back. The choice of leather or Milanese then allows you to favor the suppleness of grained leather or the continuity of metal.

About the Yema brand

Yema is a French house located in Morteau, in Franche-Comté. Its collections explore several horological universes, from sports watches to dress pieces, with an increasing place given to Manufacture calibers.

With Senans, the brand takes inspiration from the Saline royale d’Arc-et-Senans, designed in the 18th century by Claude-Nicolas Ledoux. The semi-circle plan of this architectural ensemble is found in the curve of the moon opening, linking the design of the watch to the heritage of its region.

The black Yema Senans Grande Lune opens this collection around the CMM.22, derived from the micro-rotor architecture of the CMM.20 and adapted to the Grande Lune. Find the other families in our selection of Yema watches and the Yema Manufacture collection.
