TOOL WATCH REVOLUTION:
LUXURY MEETS FUNCTIONALITY
CHRISTOPHER BÔLE
CEO & HEAD OF DESIGN
" The Yachtingraf Tourbillon Maréographe has been designed for purpose, a true tool watch able to withstand the harshest conditions. It features a double dome sapphire crystal, a unidirectional count-up sapphire bezel, 10 ATM water-resistance, high anti-magnetic resistance (2,000 Gauss) and shock-resistance (5,000G) as well as an innovative tide indication complication animated by an exceptional and precise tourbillon caliber offering over 4 days power reserve.
This unique set of features is uncommon since tourbillon watches are mostly designed as watchmaking art pieces that are delicate in their utilization. This is one of the rarest tourbillons built for daily use, a luxury timepiece that is as rugged and functional as it is beautiful and refined, a tool watch in the lineage of YEMA watches. "
DOUBLE DOME SAPPHIRE BEZEL & CRYSTAL
The unidirectional rotating bezel is characterized by its luxurious finishes. It is crafted from scratch-resistant, slightly domed sapphire, requiring a much more sophisticated and time-consuming manufacturing process. The bezel is completed by an insert with a minimalist 0-60 graduation and a luminescent marker at noon.
This collector's timepiece is also equipped with a high-quality double-domed sapphire crystal 2.20 mm high, offering better readability, increased resistance and a resolutely vintage appearance.
YACHTINGRAF ICONIC DIAL
The dial takes inspiration from the aesthetic codes of the 1970’s Yachtingraf iconic model. It features a sunray black finish with applied markers coated with Super-LumiNova and a colorful Maréographe register reminiscent of the regatta-style Yachtingraf vintage model completed with a tides indicator in the form of a small hand gracefully decorated with YEMA’s logo. The 60-second tourbillon boasts a mesmerizing kinetic spectacle for the wearer as it beats and turns against the partially open dial.
STEEL / BRONZE CASE
& SAPPHIRE DISPLAY CASEBACK
The case design combines both sportiness and elegance while ensuring a 10 BAR water resistance. Available in steel or bronze, it features different finishes with vertical brushing and polished beveled lugs and a circular brushed bezel. With a 42.5mm contained diameter and a 12.3mm thickness (14.5mm including the double-domed sapphire crystal), it offers balanced proportions for such a timepiece. The 20mm lug allows a wide choice of bracelets. The transparent exhibition caseback reveals the beating heart, it shows off the distinctive architecture of the CMM.30 tourbillon caliber creating a fascinating experience for the true enthusiast. The caseback outer ring is engraved with a unique Limited Edition number (XX/75) and a serial number (XXX-XXX).
FKM VITON® RUBBER BRACELET
Made from premium quality FKM Viton® rubber, providing utmost durability while remaining easily pliable, comfortable, dust repelling and highly resistant to tearing. The elegant 316L Stainless Steel folding clasp, available in brushed steel and IP bronze, adds style and comfort.
DISCOVER
TOURBILLON CALIBER
Invented by French horologist Abraham-Louis Breguet in 1795, the tourbillon is an advanced regulating organ present in certain high-end mechanical watches, intended to improve the precision of timepieces. It consists of a rotating cage containing the balance wheel and its hairspring, the escape wheel, the lever and the second wheel which drives it. The cage rotates 360 degrees every 60 seconds, which counteracts the effects of gravity and reduces any positional errors of accuracy. The tourbillon embodies watchmaking know-how, only a few Manufactures master the creation of this caliber masterpiece.
MARÉOGRAPHE COMPLICATION
The Maréographe consists of a tide complication placed in an elegant register. To make this magnificent phenomenon of nature visible, an elegant small hand indicates high and low tides by making gradual half-revolutions every 6h 12m 7.89s (change from high tide to low tide and vice versa) and a full revolution every 12h 25m 15.79s.

For Olivier Mory, astronomy is a family passion that spans several generations, so for him it was natural to work on a complication linked to the movement of the stars, in this case lunar time and terrestrial tides.
The Earth revolves around the Sun by rotating on its own axis. The duration of this rotation on itself is the average day (24 hours).
The Moon orbits the Earth in 29.54 days in the same direction as the Earth rotates. The Moon gets a little ahead of the Earth each day, the duration of the Lunar Day is 24 hours 50 minutes 31 seconds.
The tidal cycles are conditioned by the gravitational forces exerted by the Moon during its rotation around the Earth. By integrating the lunar time on a mechanical watch then by synchronizing the tides to local time, this makes possible to display local tides with rigorous accuracy.

Entirely designed and developed by Olivier Mory in La Chaux-de-Fonds, the regulating organs are manufactured in Switzerland while the bridges and mainplates are manufactured by YEMA in its Morteau workshops.
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 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 tourbillon movement components, including the watch case, dial, and hands, 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.
