DE BETHUNE - DB25 Starry Varius Chronomètre Tourbillon

Just as Abraham-Louis Breguet had invented the tourbillon to meet the technical constraints facing marine chronometers, De Bethune invented its own version to suit the new dynamic of wristwatches. Today, a wristworn timepiece endure considerably more intense ‘torture’ than were marine chronometer’s in Breguet’s day. Changes of position are swift and random and the brutal kinetic forces to which watch mechanisms are subjected deserves close attention.

All of which explains why the DB25 Starry Varius Tourbillon combines horological refinement with a technical feat. Its key characteristics include:

•    A mechanical in-house DB2109V4 movement equipped with De Bethune’s latest titanium balance wheel (featuring white gold inserts), entirely optimized for temperature changes and air penetration. Regulated via the De Bethune balance spring with its patented flat terminal curve maintaining a perfect centre of gravity;

•    An oscillator operating at a frequency of 36,000 vibrations/hour enabling the 63-part tourbillon to achieve astonishing accuracy on the wrist corresponding to +/-1 second per day. Weighing in at just 0.18 grams, it’s one of the fastest and lightest tourbillons in the entire watch industry.

•    Jumping seconds ensuring high-precision reading and consisting of two coaxially mounted seconds (fourth) wheels and a double pallet lever with four ruby pallets

•    An original 42mm case in polished titanium, with perfectly integrated lugs ensuring ideal comfort on the wrist;

•    A blued titanium and gold stamped dial personalised according to a given date or geographical location. Crafting using the traditional gold leaf guilding method enhanced by laser beam micro milling, a Milky Way pattern joins the De Bethune constellation.
