One of the most unique watches in every sense of the word is the new De Bethune DB28xs Purple Rain ref. DB28xsPR. A purple watch in purple polished grade 5 titanium that is the result of thermal oxidation that De Bethune masters. This is the very first time that the brand has created a watch that has been purpled; however, De Bethune’s expertise goes to great lengths in mastering the art of bluing metals with the use of heat as the old watchmaking technique demands.
