Morteau based French watch brand YEMA celebrates its 75th anniversary by launching the Yachtingraf Tourbillon Mareographe Limited Edition.
Entirely designed and manufactured in Morteau and the Franco- Swiss Jura valley, this high-complication wristwatch with high-end finishes available in steel and bronze editions and limited to 75 numbered copies each.
This new luxury tool-watch with tourbillon and tidal complication marks the 75th anniversary of YEMA and its gradual transition towards a vertically integrated watchmaking Manufacture.
Each YEMA Yachtingraf Tourbillon Mareographe watch houses an exceptional hand-wound tourbillon caliber designed by Olivier Mory, a renowned French Watchmaker Developer based in La Chaux-de-Fonds.
Named CMM.30 (Calibre Manufacture Morteau 30), the innovative mechanical high-complication movement features a 31mm diameter tourbillon at 6H with free-sprung balance wheel, LiGa anchor and escapement wheel, tidal cycle mechanism and 19 jewels.
Beating at 3Hz (21 600 A/h), this 130-part movement offers a power reserve of 105 hours (4 days approximate) with its large mainspring barrel. Enhanced with ALD (Atomic Layer Deposition) surface treatment, this anti-magnetic and shock resistant calibre also offers an accuracy of -3 / +7 seconds (adjusted in 6 positions).
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.
A true tool watch able to withstand the harshest conditions, the Yachtingraf Tourbillon Maréographe features a double dome sapphire crystal with 2.2mm thickness and a unidirectional count-up sapphire bezel with 0-60 graduation.
The black dial with sunray finish boasts the magnificent tourbillon complication at 6 o’clock. The Maréographe sub-dial at 12H features an elegant small hand that 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.
Available in stainless steel or bronze, the case measures 42.5mm in diameter. Its thickness is 12.3mm (14.5mm including the double-domed sapphire crystal) and lug/strap width is 20mm.
