De Bethune’s DB25xs Sand Winds uses random guilloché and oxidative heat treatment to create a textured yellow titanium dial. The polished grade 5 titanium case measures 40 mm. Inside, the hand-wound DB2005 runs at 28,800 vibrations per hour, with the manufacturer specifying a six-day power reserve. The brand also identifies a titanium balance with white-gold inserts and its triple pare-chute shock system. The useful collector distinction is that the colour is part of the material treatment, not simply a conventional painted dial.
