Introducing the Audemars Piguet Royal Oak Concept Split-Seconds Chronograph GMT

It’s worth mentioning that the cal. 4407 now includes an overcoil hairspring, which the original cal. 4401 lacked. Although it’s a minor upgrade compared to the complications, the overcoil hairspring demonstrates the watchmaker’s attention to detail and commitment to precision timekeeping.

At the same time, the newest Concept watch features a reimagined case that emphasises geometrical facets and highlights its angular profile. The octagonal bezel remains similar, but the case middle and lugs have stronger lines and more nuanced finishing, giving the watch an upscale look while enhancing its avant-garde feel.

To complement the upgraded case, the dial has been opened up to showcase the mechanics within, with a design reminiscent of a movement bridge. The dial is crafted from a single piece of German silver, cut in a geometric shape, and finished with a black PVD coating and polished bevels.

Over two decades after the Concept line’s debut, Audemars Piguet continues to push the boundaries and occasionally delivers surprises. The latest Concept watch is the most noteworthy since the Laptimer Michael Schumacher, which was an incredibly complicated watch with three column wheels to facilitate different operations for measuring lap times. Despite not being as complex, the most recent Concept watch stands out for its pure, classic appeal in its execution of the chronograph complication, which embodies both split-seconds and flyback functions.
