The De Bethune DB Kind of Two Jumping GMT is a study in duality – two dials, two identities, and two time zones. And it’s all united by a single, exceptionally sophisticated movement. Launched during Dubai Watch Week 2025, this reversible timepiece exemplifies De Bethune’s fusion of freedom, function, and mechanical purity. While double-sided watches have existed for centuries, De Bethune’s interpretation elevates the idea with contemporary engineering and artistic refinement, turning duality itself into a creative principle.
At the heart of the watch is a technically intricate mechanism that keeps the hands moving clockwise no matter which side is facing up. One smooth swivel transforms the watch from contemporary to classical, from home time to travel time, allowing the wearer to select the display that suits their mood or destination. This seamless dual timekeeping is made possible by a complex assembly of gears and pinions, neatly hidden beneath the surface yet central to the watch’s intuitive GMT functionality.
The contemporary front dial puts De Bethune’s mechanical artistry on full display. Anchored by the balance wheel at 6 o’clock, it layers polished surfaces, domed forms, microlight textures, beveling, and snailing to create a deep, architectural landscape. Despite the compact space, De Bethune incorporates both a jumping seconds and GMT complication, highlighted by two central gold wheels and a sculptural deltoid-shaped titanium bridge. Blued steel hands with satin-brushed inlays ensure legibility while adding a subtle play of color and light.
Flipping the watch reveals a more classical expression. A domed anthracite dial with guilloché finish offers traditional charm, complemented by manually polished 5N gold hands and gilded markers. A polished titanium indicator tracks the mechanical seconds jump, echoing the precision found on the contemporary face but in a more understated tone.
The 43mm polished Grade 5 titanium case is as technical as it is elegant, featuring De Bethune’s iconic floating lugs and a 42-component swivel mechanism engineered to handle daily wear, temperature shifts, and moisture. Despite its sophistication, operation is straightforward: the crown sets home time on the contemporary side, while pulling it to the second position adjusts the GMT display on the classic side.
Ultimately, the DB Kind of Two Jumping GMT is another spectacular example of the brand’s ability to craft highly complicated timepieces with an ultra-modern edge.
