The first curved chronograph movement was made in 2016 by Bulova, an American brand that knows a lot about technical innovation, with its high-frequency quartz calibres devoted to the pursuit of maximum precision. Mention need only be made of Accutron, which in 1960 was the world's first fully electronic watch equipped with a tuning fork oscillating at a frequency of 360 Hertz, almost 150 times faster than the oscillations of a mechanical balance.
The expansion of the brand over the years and technological developments since its acquisition by the Citizen Group in 2007 have led to new developments in the quest for precision. In 2010, the launch of Precisionist represents another important step.
The goal was to solve the problems affecting the accuracy of a quartz watch, which was achieved thanks to an innovative three-tooth crystal, which produces a frequency of 262 kHz. This frequency is eight times higher than normal two-tooth quartz, whose crystal oscillates at around 32 kHz.
Curv was born precisely on the basis of a movement with Precisionist technology, which in the NR20 calibre translates into an accuracy of + 0 -5 seconds per month. What is curved is not only the case (44 mm x 10 thick) - unusually slim and aerodynamic for a chronograph - but the movement itself, with an optimal ergonomic result. The first Curv collection comprised 12 models, available in more classic or sporty designs. Prominent among them was the version with a titanium case, which showed the curved movement through the transparent back.
When an idea proves to be successful, it is only right to exploit its full potential, which is why Bulova wanted to develop the collection. In 2018, the visible case back is provided in all versions, skeleton variants are introduced and even a steel bracelet. The next stylistic evolution is dated 2021, when a tonneau version is also offered alongside the round shape of the case, which retains the curvature typical of this model.
In 2023, Bulova adds three new, more classic and refined fittings to the original model, with a redesigned case. This is accompanied by a new 5-link semi-integrated bracelet, which maintains the right fluidity on the wrist and is characterised by its polished and brushed finish.
New colours also for the dials: dark green, blue or silver, the latter partly skeletonised. The case, rounded and less angular to gain in elegance, extends outwards to better embrace the winding crown. Finally, the pushpieces take on an oval shape as opposed to the squarer ones of previous versions.
