Hands-On: De Bethune DB28 Yellow Tones
Even amongst avant-garde watchmakers, De Bethune stands out for its substance – aesthetic and material innovation matched by technical ingenuity. At its core, the brand has reimagined the most fundamental aspects of mechanical timekeeping, from the barrel to the hairspring, while pushing the boundaries of traditional complications, be it the moon phase, tourbillon or chronograph. But arguably its most distinctive innovation is an aesthetic one, which has come to define the brand no less – heat-blued titanium. The brand has used the alloy for more than 15 years across various parts of the watch, even making almost a whole watch out of it. But now De Bethune has a twist on the theme, resulting in the DB28 Yellow Tones in brilliant golden titanium.

In fact, it looks more like fresh brass than gold. The colour was achieved through thermal oxidisation of the surface, essentially the same process as that used for blued titanium (and also the same for blued steel). The yellow surface, just like the blue, is the result of an oxide that forms on the surface of titanium when it is heated to a certain temperature. But amber yellow tone in this case was created by heating it at a lower temperature than used for blued titanium. Titanium undergoes different stages of oxidation when heated, and yellow is o...
