The De Bethune DB28XS Sea Tourbillon distills the brand’s passion for precision and poetry into a striking, ocean-inspired timepiece. The blued titanium dial is the star of the show, decorated with a random guilloché pattern that plays with light like sunlight hitting moving water. It shifts, shimmers, and constantly changes depending on the angle. Despite this rich visual texture, the watch remains easy to read, thanks to clean white markers and polished hands that stand out clearly against the deep blue background.
Housed in a refined 39mm case, the DB28XS Sea Tourbillon is made entirely from mirror-polished titanium, offering both lightness and durability. Despite its technical complexity, it wears effortlessly thanks to De Bethune’s patented floating lugs, which adapt naturally to the wrist for superior comfort. The brand’s mastery of titanium is on full display here, an unforgiving material that demands exceptional skill to polish to a flawless, distortion-free finish. The result is a sleek, ergonomic case that feels almost weightless.
At its core beats the hand-wound DB2009V7 calibre, a movement engineered for performance and reliability. A twin-barrel system delivers over five days of power reserve, while advanced components such as a silicon escape wheel enhance resistance to shocks and magnetic fields. The highlight is the ultra-light, high-frequency tourbillon, operating at 36,000 vibrations per hour and completing a rotation every 30 seconds. Constructed from titanium and weighing just 0.18 grams, its exoskeleton design improves both efficiency and shock absorption.
