The new Royal KonTiki houses the first movement with chronograph function from the Manufacture Eterna. Developed on the basis of hand-wound Caliber 39, it now not only incorporates a chronograph but also flyback, dual-time and date functions as well as automatic winding, and of course a patented Spherodrive device improving energy transmission and ensuring greater longevity. For its launch, Caliber 3928A drives a watch from the famous KonTiki collection, named after the raft built from balsa wood logs by Thor Heyerdahl for his Pacific crossing expedition in 1947. The ocean is evoked by a blue dial adorned with a central wave motif. The resolutely virile and sporting character of this model is accentuated by red, black and white contrasts, Superluminova, ceramic inserts on the bezel, as well as rubber clothing the pushers and strap.
