    The DB28T, a technical development of the DB28, adopts the same case in polished titanium held by double floating lugs for maximum comfort. Its mechanical caliber with hand winding is equipped with a high frequency, ultra fast tourbillon, signed De Bethune. The lightest in the world with its minuscule 0.20 grams for 63 parts, it beats at one-tenth of a second and makes a complete rotation in 30 seconds for superior chronometry. Its silicon balance wheel, just as its escape wheel, is encircled with a white gold ring. A self-regulating twin barrel developed in-house ensures constant torque in the movement. Entirely visible, the movement presents a curved delta motion work bridge in polished titanium decorated with applied microsphere stars in white gold.
