A seemingly simple concept is often the most difficult to bring to fruition, as De Bethune remarkably demonstrates with the DB25 World Traveller, which uses creative mechanical thinking to achieve exemplary functionality and legibility. The concentric dial layout allows world time to be read at a glance. The hour in a second time zone is shown on a central disc, circled by a microsphere that also indicates whether it is day or night-time. Local time, meanwhile, is displayed on the chapter ring, while the date is read from the outermost circle. A pleasure to behold, the classic aesthetic of the DB25 World Traveller's dial and 45-mm white gold case is the continuation of a carefully nurtured philosophy. Mechanical performance drives functionality by means of the manual-winding DB2547 calibre, the brand's twenty-fifth in-house movement.
