YEMA 2000 / YEMA 3000

IN-HOUSE CALIBERS

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.

YEMA2000/3000 CALIBER

PROGETTATO E ASSEMBLATO LOCALMENTE

I nostri calibri interni di seconda generazione YEMA2000 e YEMA3000 sono progettati e assemblati nei nostri laboratori di Morteau (Francia) dai nostri orologiai, mentre la produzione dei componenti è effettuata da partner asiatici e svizzeri. Questo approccio ci consente di offrire calibri interni di qualità standard progettati e assemblati dai nostri orologiai a prezzi competitivi e accessibili.

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.
