Within the Arena collection, the steel used on the original models has since given way to innovative metals. The Arena Biretro and Arena Chrono Quattro Retro models, measuring an impressive 45 millimetres in diameter, have been showing up in a new outfit each year since 2005. Each version radiates its own inimitable aura of casual charm: an ultra-light titanium case, or a luxurious typical Gérald Genta mix of materials: gold for the case with its fluted middle, and tantalum for the bezel. This time, the white gold turns red, lending the watch a delightfully warm and eccentric charm. The accentuated contrast is reflected on the dials enlivened by the brand’s signature complications.
The Arena Biretro sends luminescent hours jumping past a window at 12 o’clock. In order to be charged with all the light they need, they appear three hours ahead of time beneath an orange-coloured sapphire crystal. The astonishing retrograde minute hand moves over the arc of a circle featuring applied gold numerals, while the identical date display counts off the days against an engine-turned background. All these indications are arranged within an asymmetrical design featuring a sophisticated play on shapes and colours.

The Arena Chrono Quattro Retro models, embodying the quintessence of the grand art of complications according to Gérald Genta, are the first watches to combine a jumping hour with four retrograde functions: minutes at 12 o’clock, bidirectional date display at 6 o’clock, 12-hour and 30-minute counters at 9 and 3 o’clock respectively. The functions all operate on a sophisticated multi-layered dial that appears in silvery grey, anthracite and black versions enhanced with red gold accents to match the case. The bright red hands stand out boldly against this understated background, reinforcing the unmistakably powerful character of the Gérald Genta brand!
