Dubey & Schaldenbrand are releasing their new Grand Shar DBT Tourbillon(seen here at JCK), a model that beats at 21,600 vib/h. This tourbillon movement is housed in a lightweight case formed from titanium grade 5 and treated by a patented oxidation process that increases the hardness of the material and its mechanical resistance. The unique color of the titanium case is due to in house electroplasma treatment.
