The dial features the "De Bethune blue" so inextricably linked to the brand. In the center of the DB28XS is that blued titanium, finished with a world's first "random guilloche." That pattern gives the wave-like texture, finished with white gold dots to mimic the reflection of light on water. The chapter ring is silver plated with transferred Arabic numerals and blue dots on the minute track, link with custom-made titanium hands.
