De Bethune DB25GMT Starry Varius

De Bethune presents DB25GMT Starry Varius, a slim and elegant traveller’s watch that combines traditional expertise with cutting-edge technology.

The new DB25GMT Starry Varius watch incorporates all the inherent codes of the DB25 Starry Varius collection, namely a polished grade 5 titanium case with a 42 mm diameter, a starry sky accompanied by its Milky Way, perfectly integrated open-worked lugs, and a screw-down sapphire caseback providing a glimpse of the movement.

Starting from the centre, the dial indicates the date on the first disc with the help of its jumping date hand, which can be adjusted via a corrector at 6 o’clock. The hours of the first 24-hour time zone (home or reference time) are marked by the microsphere in a mysterious manner, as it appears to be floating weightless in its corridor.

This function can be set in both directions (clockwise/counter-clockwise) via the crown. Local time, i.e. the second time zone, is indicated by the blued hands whose curvature follows the relief of the dial. The minutes hand naturally remains coordinated with the reference time, while the hours hand indicates the local time thanks to the second time zone. Local time can also be set by the crown, in both directions.

Despite its complex construction, the mechanical GMT movement is very simple to use, with concentrically arranged functions. First of all, the owner uses the crown to set his reference time, known as home time, which is indicated by the microsphere on the 24-hour dial.

Representing De Bethune’s technical signature since its development of the three dimensional moon-phase display, this microsphere indicates day and night thanks to its two halves: one blue and the other pink. It gradually turns at 6am and 6pm, thereby imitating sunrise and sunset. Secondly, the wearer sets his second time zone by means of the hours hand which is controlled via the crown pulled out to the second position.

In the centre of the curved dial, you can view a poetic vision of the sky by day and by night. A polished pink gold sun in the centre of a microlight shines over half the disc, while the celestial vault is delicately outlined on the blued polished titanium section. The vision provided is of a miniature night sky, dotted with a multitude of small white gold pins delicately and individually driven into a blued titanium dial. The Milky Way is then hand-crafted using micro laser strokes and 24-carat gold leaf.

Visible through the sapphire caseback, the reverse side of the movement reveals the latest titanium balance with white gold inlays. This organ has the ability to neutralise the effects of temperature variations thanks to its interaction with the balance spring featuring the “De Bethune” flat terminal curve. Its aerodynamics has also been worked on so as to ensure minimal air resistance. The escape-wheel is made of silicon both for the lightness of the material and to increase the power of the calibre.

The regulator is held in place by a triple pare-chute system which combines a titanium bridge integrating two jewels held in place by a leaf-spring system pressing on the jewels. The two barrels, which are partially visible, have a five-day power reserve thanks to a self-regulating energy mechanism.

This timepiece is equipped with the latest hand-wound Calibre DB2507. This is the 29th movement from De Bethune, which once again demonstrates bold technical mastery and expertise by fitting a GMT movement into a Starry Varius case and reproducing a miniature starry sky. The complication and its display have been entirely redesigned with a view to optimising legibility and operating convenience, thereby ideally meeting travellers’ expectations.
