De Bethune is heading the fleet of brands that go for radical options, dare to sail against the tide and thereby place new route markers on the ocean of watchmaking creativity. Following in the wake of the nine patents and eleven calibres developed by the Manufacture De Bethune in the space of a few years, the DB28T is equipped with Calibre DB 2009 featuring the world’s lightest titanium-silicon tourbillon: its 50 parts weigh between 0.0001 and 0.0276 grams and total 0.18 grams between them. Its frequency is an impressive 36,000 vibrations per hour, its carriage performs two rotations per minute, and its thermocompensated balance wheel is made from silicon and palladium. The De Bethune DNA is visible in the extreme level of technological and aesthetic osmosis expressed through the spherical moon-phase display, the delta-shaped polished steel mainplate with the De Bethune “stripes” motif, the patented “floating lugs” that adapt to the size of the wrist and its various movements, and a complex hunter-type shaped perfectly polished titanium case with a power-reserve indication on the back. The DB28 collection also comprises a one-of-a-kind model created as part of Only Watch 2011 (see our Unique Piece feature).
