The heart of the watch is the movement. Apparently, Bvlgari tried to emphasize this by naming the watch after the movement that beats inside its case – the Bvlgari Diagono Calibro 303. The movement of the timepiece has a particularly important function. Thanks to its small size, the Bvlgari Diagono Calibro 303 is the world’s thinnest self-winding watch.

Just 5.5 mm thick and 42mm wide, the round case of the timepiece is made from stainless steel. At first sight, it seems that the bezel of the Bvlgari Diagono Calibro 303 is also crafted from this material, but, after looking at it attentively, it becomes clear that it is made from white gold. The bezel has the distinctive “Bvlgari” signature engraved across it.

The inside of the case contains the Calibro 303, composed of 303 elements and set with 37 jewels. The movement of the watch is aesthetically pleasing as well as functional – it provides a power reserve of 45 hours and beats 21,600 times per hour, ensuring an immaculate performance of the timepiece. As usual, the movement can be admired through a transparent case back.

But what is truly worth admiring is the dial of the Bvlgari Diagono Calibro 303. It has a three-layer structure with various kinds of finishing. The first layer is a metal base decorated with a sunburst pattern. Then comes the anthracite layer with vertical treatment, and the upper layer is represented by three sub-dials and faceted hand-applied markers.

The hands of the watch, as well as the hour and minute counters at 3 and 9 o’clock are rose-gold toned, while the seconds sub-dial at 6 o’clock comes in different colors, depending on the color pattern of the dial.
