To devise the new dual-dial watch , De Bethune had to re-design its famed floating lug case to allow the flip-over case to pivot easily , rotate on its central axis and then to click into place securely . This operation is a simple one because the brand equipped each side of the case with a clever rotating mechanism made up of twenty-eight steel and titanium components .
Equally important is the case ’ s middle section , which swivels naturally and frames the case and the crown , which lands gracefully at either 6 o ’ clock or 12 o ’ clock , depending on which side of the DB Kind of Two Tourbillon the wearer chooses to view .
Inside the watch De Bethune ’ s Caliber DB2579 features patented technical flourishes well known to De Bethune devotees . These include a titanium balance with white gold inserts ( optimized for temperature differences and air penetration ) and a self-regulating twin barrel . For the tourbillon , De Bethune utilizes the ultra-light , 30-second titanium design it first debuted in 2008 . Price : $ 250,000 .
