De Bethune presents the DB 25 World Traveller, an intelligent watch featuring a second time zone and world time expressed with a mysterious display. The exceptional ease of use and convenient systems for setting and display make this timepiece a world premiere.
The DB25 World Traveller is designed to become a loyal companion for the long-distance traveller. Although the invention of multiple time zones dates back to the 17th century, the readability and adjustment of the functions on a wristwatch have never been so simple and intuitive. The system is completely secure and each indication can be controlled independently. Once again, De Bethune stands out from the pack at inventing a timepiece that is simple in appearance but conceals a gem of technical intelligence.
Visually, the refinement of the DB25 World Traveller lies in the concentric arrangement of the functions. World times appear on a disc in the centre of the dial, encircled by a graduated channel in which a moving microsphere indicates the reference time - also known as the home time. This microsphere, a technical signature of De Bethune since their invention of the three-dimensional moon-phase, has two halves that allow it to also indicate day and night.
The DB25 World Traveller is equipped with mechanical calibre DB2547 with manual winding, the latest manufactured. The regulator is equipped with a new evolution, a titanium balance wheel with white gold inserts, developed particularly for optimal management of temperature variations.
Starting in the centre, the dial indicates world time, which is set using an almond-shaped push-piece positioned at 8 o'clock. This flexible and precise system moves the city display disc, which is decorated with concentric Microlight, by one-hour clockwise jumps. The first time zone, is displayed with 24-hour markers and indicated with a mysterious display by the position of the microsphere, which appears to float weightlessly in its channel. At 6 a.m. and 6 p.m., the microsphere pivots on itself to present a pink gold face for daytime, or a back side in blued steel for the night. Local time, is indicated by the blued leaf-shaped hands. The minutes hand remains naturally coordinated with the reference hour. The day indication is the last circle on this display, with a design that evokes the solar system. The day is coordinated with local time.
The DB25 World Traveller transforms the way that a second time zone can be displayed along with a world time indicator. True to the De Bethine approach that focuses first and foremost on the reason behind any watchmaking function, David Zanetta and Denis Flageollet have aimed to make the display correspond ideally to the traveller's needs. They focused their research on readability and comfort, both wearing the watch and in manipulating settings.
