The cosmos holds a particular place within the coronary heart of Denis Flageollet, founder and grasp watchmaker of De Bethune. Watches impressed by starry night time skies with De Bethune’s signature blued titanium touches appear to have been cast in a far-away galaxy. The DB25 is the extra classical face of the model with extra compact dimensions and a reverence for conventional watchmaking, essentially the most notable model being the Starry Varius. The newest DB25 to emerge from the model’s manufacture in L’Auberson is the Starry Varius Aérolite, a surprising variation of the award-winning Chronomètre Tourbillon, now with a meteorite dial. Fitted with a no much less spectacular motion with a high-frequency tourbillon and deadbeat seconds, the mechanical fireworks are hidden on the reverse aspect of the case.
Solid in house
Flageollet is fascinated by meteorites and claims that “no different steel is as charged with pure vitality and emotion because the iron meteorites which have taken form within the furnace of the celebs”. This DB25 shouldn’t be the primary mannequin to flaunt a meteorite dial, and a number of other fashions, together with the dial of the DB28XP, have been given the house rock therapy. The meteorite used for this mannequin is named Muonionalusta, one of many oldest meteorites to strike our planet a couple of million years in the past, someplace between Finland and Sweden on the banks of the Muonio river. Composed primarily of iron and nickel, the meteorite is distinguished by the geometrical traces of its cross-hatched Widmanstätten sample.
Since Flageollet can be a grasp alchemist, reworking base metals into electrical blue hues, the meteorite has undergone thermal oxidation. The mysterious blue color is the results of a chemical response produced when heating the meteorite. Not solely has it been blued, however the meteorite is polished and embellished with a starry sky composed of tiny white gold pins pushed by hand into the dial and 24k gold leaf to symbolize the Milky Approach. However there’s extra, and house owners can customise the night time sky to their coronary heart’s want to replicate a specific date, time and place.
The blued meteorite disc sits low on the dial and is surrounded by a curved silver-coloured chapter ring with classical Roman numerals and a minutes monitor separated in 5-minute intervals. Breguet-style palms for the hours and minutes are accompanied by a slim third hand for the seconds. It’s price mentioning that De Bethune makes its personal palms in-house; the palms on this watch are constructed from metal and polished by hand, and the minutes and seconds palms are barely bent at their tricks to alight on the rounded chapter ring.
One in every of De Bethune’s most veteran fashions, the DB25 is available in a fantastically polished grade 5 titanium case with a restrained 42mm diameter and a thickness of 10.3mm. In contrast to different fashions just like the DB28XP with floating articulated lugs that encircle the case, the lugs are built-in, hollowed and tapered. Regardless of the deceptively simple capabilities on the dial, there may be much more happening than meets the attention.
Full of improvements and patents, the DB25 Starry Varius Aérolite is fitted with the identical manual-winding motion – calibre DB2109V4 – that received the chronometry prize on the GPHG in 2018. Designed, developed and produced at De Bethune’s workshops in L’Auberson, the view from the caseback is as fascinating because the dial with a mirror-polished, delta-shaped bridge dominating the surroundings. The bridge is positioned above the 2 self-regulating, hand-snailed barrels delivering a 4-day energy reserve. To reinforce the chronometric efficiency, Flageollet has integrated a high-frequency tourbillon motion, performing its 30-second rotations beneath the blued titanium delta bridge. Ticking at 36,000vph (5Hz), the titanium and silicon tourbillon is suspended in an ultra-light carriage weighing simply 0.18g (a 2008 De Bethune innovation and the lightest carriage within the trade).
The stability wheel can be manufactured from blued titanium with white gold inserts and optimised for temperature variations and air penetration (a 2016 De Bethune patent). The stability spring is confected in-house and has a flat terminal curve (2006 patent) to take care of an ideal centre of gravity, and the escape wheel is crafted in silicon. Final however not least, the central seconds hand jumps each second, due to De Bethune’s patented Useless Beat Seconds (2011).
