The DB28 steel-wheeled sapphire tourbillon watch is faithful to the vision of the founder of De Bethune and watchmaker Denis Flageolet. Its sleek and tight lines and movement are infused with the latest technological advances. In these developments, the iconic triangle-shaped bridge and the sapphire crystal tube cover (the blue of the bridge and the transparency of the tube cover) jointly produce reflections, magnifying the structure of the movement and making the eyes look at its heart.

The laser-cut sapphire glass component perfectly matches the shape, bulge, angle and teeth of the bridge and barrel cover; the outer ring of the lens barrel is surrounded by a polished titanium ring. For the first time, the brand uses triangular gemstones for sapphire-shaped bridges, bucket lids and laser-cut glass. The thickness of the sapphire crystal of the bridge is 1 mm, “to ensure functional rigidity”, while the thickness of the sapphire crystal of the barrel cover is 0.3 mm, which, according to the brand, “can resist small daily vibrations.”
The sapphire crystal triangle bridge, lens barrel cover and laser cut glass are the brand’s first products.
