De Bethune bills its new DB25 GMT Starry Varius as the smaller (42mm) alternative to the 45mm DB25 World Traveller, which debuted in 2016. For the most part, that’s true, though you won’t find a series of city names positioned around the dial on this new dual-time model to quickly display global times.
The new watch, however, adds a GMT function to the displays, which smartly retains the original model’s multi-level, concentric spheres and its unusual miniature gold and blued-steel orb, dubbed the ‘microsphere.’
In its smaller guise (42mm by 11.8mm), the new watch also retains other characteristics De Bethune builds into its entire DB25 Starry Varius collection. These include a polished grade-5 titanium case, a starry sky accompanied by its Milky Way and De Bethune’s characteristic integrated, open-worked lugs.
Reading the dial
With the date visible in the central disc visa a jumping hand, the two time zones can be discerned with a check of the blued central hands (local time) and the mysteriously circling dual-metal orb (second ‘home’ time). You’ll even know whether it’s daytime or nighttime at home thanks to the orb’s two halves: one blue (evening) and the other pink gold (daytime). For added realistic affect, the slow-rotating microsphere very gradually reveals both sunrise and sunset.
To add an even more poetic display to the dial, De Bethune places a polished pink gold sun in the dial’s center, just across from the beautifully blued and polished titanium miniature night sky dotted with white gold ‘star’ pins.
De Bethune powers its new DB25 GMT Starry Varius with its hand-wound Caliber DB2507, the independent watchmaker’s twenty-ninth movement.
Visible through the watch’s sapphire caseback, the movement operates by drawing on an extensive list of advanced features, all of which again underscore De Bethune’s well-earned reputation for technical mastery.
Just a partial list of these features includes: A titanium balance with white gold inlays, a balance spring with a De Bethune flat terminal curve, an escape-wheel made of silicon and a regulator held in place by a triple pare-chute system which combines a titanium bridge held in place by a leaf-spring system. The movement’s two barrels, which are partially visible from the caseback, boast an impressive five-day power reserve. Price: $110,000.
An additional slice of the chosen stone will also be inserted into the movement itself. All watches will be set with the Bulgari manual-wind caliber BVL206 with flying tourbillon.
