Louis Moinet, the Switzerland based manufacturer of highly exclusive wristwatches, equips its award winning Mecanograph timepiece with a dial made from 150-million-year-old fossilized dinosaur bone.
Mecanograph City watches from Ateliers Louis Moinet incorporate fragments of lunar meteorites and other rocks from the far-flung corners of the universe. Meanwhile, timepieces from the Treasures of the World collection boasts dials made from rare, fossilized stones of mineral or plant origin, including petrified exotic wood. Now, the two approaches have now been combined: the Jurassic Watch, derived from the Mecanograph family, is the first to feature a dial made from Jurassic-era dinosaur bone – between 145 and 200 million years old.
The mechanical heart of the Jurassic Watch is the certified Mecanograph chronometer. This proprietary movement has been exclusively developed by Ateliers Louis Moinet. It boasts not only extraordinary precision, but also a dial made from a genuine fossilized 150millionyear-old dinosaur bone. In another first, the caliber features a date window located at 3 o’clock. It also uses the exclusive Energie Plus process, unveiled by Louis Moinet at Baselworld. “Energie Plus” makes it possible to wind up the watch in both directions, with a minimum of excess travel. This optimizes each movement of the rotor, recovering its energy, and winding the movement more effectively. It comprises an automatic system, based on an automatic pawl winding system featuring an elegant spring with a ‘crab claw’ design. Completing the system, a miniature ceramic ball bearing is mounted on the dual-material rotor.
Specific craftsmanship is vital for the production of each dial. It begins with the choice of the right stone; this needs to be sufficiently dense to be worked on, taking into account its final size and texture. The ensuing handiwork takes over a week – and results in a dial thickness of just 0.65 mm.
The dinosaur bone, discovered in North America, has been authenticated by renowned geologist Dr Andreas Stucki in association with the Aathal Dinosaur Museum in Switzerland. The dinosaur bone is from the family of large herbivores, which also includes the Diplodocus. The Diplodocus is one of the most easily recognizable dinosaurs thanks to its highly distinctive shape, featuring both a long neck and a long tail. It was one of the longest dinosaurs, measuring up to 50 metres – and had an estimated weight of 50 tonnes.
