FRANCO-SWISS ACCURACY
With its Swiss regulating part, the CMM.30 tourbillon is a high-precision movement ensuring high performance. The free-sprung balance wheel regulates isochronism for lasting precision and stability. In the absence of a regulator, the durability of the hairspring is increased, as is long-term precision. Adjusted in 6 positions, the CMM.30 ensures an accuracy of –3 and +7 seconds per day.
105 HOURS OF POWER RESERVE THANKS TO A LARGE BARREL
The CMM.30 has a single large barrel optimized to ensure a power reserve of 105 hours. Specifically manufactured for the CMM.30 by Générale Ressorts, this large barrel is off-centered in order to make enough room for the gears and the balance wheel so as to preserve a contained thickness.

OPTIMIZED ESCAPEMENT
Interface between the gear train and the regulating organ, the escapement is the place where energy and chronometry intersect in a complex interaction. The escapement is an energy-demanding system, it alone consumes more than half of the barrels’ energy. It is the friction of the anchor pallets on the anchor which, despite their lubrication, dissipates a good part of this energy.
The CMM.30 tourbillon escapement presents notable improvements which reduce this friction thanks to an innovating and particularly sophisticated manufacturing process (LiGA technology). This advanced escapement ensures optimization of the entire mechanics, precision and longevity of the caliber components.
ANTI-MAGNETIC
& SHOCK-RESISTANT
Designed for everyday life, the CMM.30 presents robust technical characteristics for a tourbillon caliber. Equipped with non-magnetic components, such as a Swiss-made non-metallic alloy hairspring, a Glucydur balance wheel with an adjustment mass made in gold and micro-components manufactured with LiGA technology materials, the CMM.30 is capable of withstanding exposures to electromagnetic fields up to 2,000 Gauss, a real feat for a tourbillon caliber.
The architecture of the tourbillon cage bridge with its free-sprung balance wheel and the shock absorbers manufactured by Kif make the CMM.30 impervious to shocks, vibrations, and acceleration up to 5,000 Gs in all directions.

The architecture of the tourbillon cage bridge with its free-sprung balance wheel and the shock absorbers manufactured by Kif make the CMM.30 impervious to shocks, vibrations, and acceleration up to 5 Gs in all directions.
ATOMIC LAYER DEPOSITION (ALD) DECORATION
Instead of the traditional “guilloché” decoration, the curved shape of the slightly skeletonized bridges, reminiscent of rising tide waves, privilege a minimalist, uniform and high-quality decoration in order to accentuate the contemporary aspect of our Manufacture tourbillon caliber.
The exceptional satin-finishing and micro-blasting treatment of the mainplate and bridges is carried out in black color using the latest ALD (Atomic Layer Deposition) technology by a renowned Swiss specialist in nanometric decorative coatings.
This revolutionary gas deposition process guarantees a uniform coating with a precision of approximately one nanometer, which preserves the decorative satin finish of the surface.

LOCAL PRODUCTION
Over the past two years, YEMA has made significant investments aimed at insourcing a good part of its production and constantly improving the quality of its manufacturing processes by using new equipment as well as expanding and modernising its workshops and production lines
In addition, the Franco-Swiss Jura region being increasingly integrated, YEMA now works with new local partners to secure a more responsible and higher quality production.
All Manufacture movement components are manufactured in France and Switzerland within a range of 72km from Morteau by recognized craftsman in fine watchmaking. The caliber bridges and mainplates are manufactured in YEMA’s workshops in Morteau where final assembly of all components takes place.

A DYNAMIC REGIONAL WATCHMAKING ECOSYSTEM
YEMA workshops are based in Morteau, the cradle of French watchmaking, a few steps from the Swiss watchmaking region. This cross-border watchmaking community concentrated along the Jura mountains has gradually transformed into a true regional ecosystem recognized as Intangible Cultural Heritage by the UNESCO in 2020.
