YEMA 2000 / YEMA 3000
HAIRSPRING REGULATOR
The regulator mechanism has been modified in order to better adjust the hairspring and balance wheel in all positions. The new mechanism is far more reliable, which results in more accurate regulations while avoiding accidental unregulation due to shocks when the watch is worn in the most extreme conditions.
REVERSING WHEELS
In order to counter-effect an excessive rotational effect in one and the same direction of the oscillating weight, the reversing wheels have been modified for an improved winding of the mechanism in both directions.
OSCILATING WEIGHT FINISHING
The oscillating weight has been decorated with the mentions, YEMA 1948, Maison Horlogère Française, Caliber YEMA2000.
CALENDAR DRIVING WHEEL
These components allow the date to jump every 24 hours. The new version facilitate a smoother and more precise jump.
DATE COMPLICATION
Our new calibers have the advantage of being able to be assembled without their date complication to avoid the "ghost-date effect" on no-date dial models without a date function. The disc wheels typography and colors have also been improved.
GMT COMPLICATION
Complication allowing the display of a second time zone via an independent hand.
SECOND-GENERATION IN-HOUSE CALIBERS
YEMA's In-house Calibers YEMA2000 and YEMA3000 are an evolution of our first caliber MBP1000 released in 2011. Several components have been improved in order to achieve fundamental gains in terms of precision and durability. Designed, developed and assembled by our watchmakers in our Morteau (France) workshops, our Standard Grade In-house Calibers combine manufacturing simplicity and efficiency offering great precision and reliability at a competitive price point.

CHRONOMETRIC TESTS
Our second-generation In-house Calibers have undergone numerous control tests including a final one carried out by the Centre Technique Horloger Français, a French independent institution founded in 1945 responsible of testing watch calibers made in France.
Precision has been improved to +/-10 s/d accuracy and +/-25 s/d tolerance.
TALENTED FRENCH WATCHMAKER
Nicolas Bailly
Technical Watchmaker
15+ years experience at Cartier, Pro Horlogerie, YEMA
Many French watchmakers decide to return to the French side of the valley after a few years in Switzerland, so as to join French watchmaking brands such as YEMA. This is the case of many of our watchmakers including Nicolas Bailly, our new Quality Assurance and Technical Manager who recently joined us after a previous working experience in Switzerland.
YEMA also works with Morteau’s town hall on projects aiming at further developing the watchmaking activity in the region, including a watchmaking start-ups incubator that is in the works.
LOCAL PRODUCTION
Over the past few 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 implementing latest equipment as well as expanding and modernising its workshops and production lines.
In addition, YEMA now works with new local partners in France and Switzerland within a range of 72km of its workshops, to secure a more responsible and higher quality production.
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.
