The De Bethune DB28XS Sea Tourbillon presents a reduced version of the brand’s tourbillon architecture within a slimmer 38.7mm titanium case. Polished surfaces contrast with the openworked dial, where a blued titanium bridge carries a random guilloché pattern that mimics ocean currents. The floating lug system extends from the case, allowing the watch to sit securely while adapting to wrist movement.
The manually wound calibre DB2009V7 operates with a five-day power reserve delivered through twin self-regulating barrels. A 30-second tourbillon is positioned at six o’clock, constructed from lightweight titanium components and rotating at high frequency. Structural elements of the movement remain exposed on the dial side, while hand-finished details and heat-blued components define the watch’s mechanical layout.
