De Bethune presents a new exclusive model, the DB 28 ST, equipped with a tourbillon device. It is precisely this latter complication that is at the very heart of the watch: silicon and titanium are used in its construction, and it is also the fastest (remember that the DB 28 ST's balance runs at 36,000 vibrations per hour) and lightest tourbillon device available (only 0.18 grams). The DB 28 ST also features jumping seconds in the centre of the dial, which is very beautiful in its multi-layered composition, and which shows a large part of the movement used (calibre DB2119, mechanical with manual winding, 47 jewels, 4-day power reserve). The crystal protecting the dial is sapphire, and has undergone a double anti-reflective treatment. The titanium case has a diameter of 43 millimetres, while the bezel is made of platinum. The alligator strap is fitted with a pin buckle.
