De Bethune has used SIHH this week to lift the lid on its new DB25 World Traveller timepiece, which features a second time zone and world time expressed with what it calls a “mysterious display”.
Aimed as a loyal companion for the long-distance traveller, the multi-zone system is completely secure and each indication can be controlled independently.
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 ‘home time’.
This microsphere, a technical signature of De Bethune since its invention of the three-dimensional moon-phase, has two halves that allow it to also indicate day and night.
One half is blue, the other pink, and they reverse positions when they pass 6 am and 6pm. Local time is displayed on the hour circle, and the day on the last exterior circle.
The DB25 World Traveller is equipped with the mechanical calibre DB2547 with manual winding while, for the first time, the central delta bridge is embellished with a ‘Côtes De Bethune’ decoration in the centre, produced using the Microlight micrometric engraving technique developed by De Bethune.
De Bethune is an independent brand that was founded in 2002 by curator David Zanetta and expert master watchmaker Denis Flageollet. It designs and manufactures all of its timepieces in house.
